The invention relates to a method of designing a layout of holes for sinking mine workings. For a set of holes that must be drilled in the mine workings arrangement of holes defines at least location and guides the corners of the holes in the coordinate system of the layout of the holes. In this way the designer is the layout of boreholes using CAD software. The purpose of the invention is described in more detail in the introductory part of the first independent claim.

The invention also relates to a program product in accordance with the second independent claim, the execution of which on designing computer or the like performs the operations needed to design the layout of the holes.

Tunnels, underground storage and other mining construction laid using sets of holes. In the mine workings are drilling deeper, in which lay the charges and blow up after drilling. One explosion separates the stone material from the rocks for one set of holes. For sinking mine first, create the plan, constitute theoretical profile of penetration and, for example, define the data type of rock. In General, the client also sets different requirements as regards R is rabatyvaemy production. For each set of holes on the design Board also design the layout of the holes, which put on a drilling rig for drilling holes in the rock, so that will be generated the desired set of holes. When the locations of the holes formed, it can be implemented on a rig. The excavation of mountain structures of complex shape, it is impossible to use the same layout holes for drilling the subsequent sets of holes, each set of holes may require a separate arrangement of holes or in the alternative arrangement of the holes may require modification for each set of holes.

Publication Fl 105942 B describes a solution in which the length in the existing layout of the holes can always be changed to match the length of the set of holes that must be drilled at any particular time. The initial position of the downhole during drilling moves in the direction of drilling or in the opposite direction. The location of the end points of the holes remain, but instead define a new starting point for the holes in the new home slaughter or change the directional angle of the holes. In publishing solution form drill kit bore-holes remain the same and regulate only the length of the scheme they are situated the holes.

Mining, however, may include a curved surface or the bottom set of holes that must be drilled, can be tilted horizontally or vertically. In addition, the excavation can be strongly curved when observing in the operating direction, resulting in a deviation of the layout of the holes will not provide the desired curve of small radius. In this case, an abrupt change in the length in the arrangement of the holes, as described in the above publication is insufficient. So, currently, the complex shape of the bottom sets of holes have to design manually, making multiple two-dimensional projections to determine lengths, locations and directions of the holes for the layout of the holes. However, it is slow and difficult. In addition, since the design is done using several different projections, for the designer, it will be difficult to perceive the whole and to detect errors in the layout of the holes, if present.

BRIEF description of the INVENTION

The purpose of the invention is to provide a new and improved method of designing a layout of holes for drilling bottom hole in the set of holes of complex shape. An additional objective is to provide a new and improved software is a lot of product for designing the layout of the holes.

The method of the invention differs in that it provides a design program with the profile of the face, representing the shape of the face in the set of holes that must be drilled; and place the end point of the holes that must be drilled in the locations of the boreholes, in location, in accordance with the profile of the face in the coordinate system of the layout of the holes through the design of computer, resulting in holes of different lengths in the layout of the holes define the shape of a predetermined profile of a face.

Software product of the invention is characterized by the fact that the implementation of engineering programs are designed to accommodate the locations of the end points of the holes that must be drilled in the locations of the boreholes in response to the load profile of the face, representing the shape of the face in the set of holes that must be drilled, resulting in holes of different lengths in the layout of the holes define the shape of a predetermined profile of a face.

The basic idea of the invention is that the design layout of holes applies engineering program, which provided data on the shape of the face in the set of holes, i.e. the profile of the face. Thus, based on the data provided design the program allocates to the final point of the bore-holes, included in the scheme, in the location corresponding to the profile of the face on the bottom set of holes, which results in the desired shape of the face. In this case, the holes of different lengths in the layout of the holes define the shape of a predetermined profile of the face on the bottom of the face.

The invention provides the advantage of allowing you to quickly and easily design the layout of holes for a set of boreholes containing even complex surfaces and shapes of the face, because the design program correctly locates the location of the soles of the holes, thus achieving the desired shape of the face. In addition, design the computer performs the necessary calculations required, for example, to determine the coordinates of the end points of the holes and to calculate the lengths of the boreholes. In addition, the configuration of the invention reduces the number of errors, because you no longer need in various non-automated computational stages and manual design, which must be fulfilled in different projections.

The main idea of one possible implementation is that the design of the program provide a predetermined three-dimensional model of the profile of excavation, which must be drilled. Model profile can be composed, for example, with the help of software programs which foster CAD and the like, the party ordering the construction of mining facilities. An implementation option also sets the design of the program the location of the set of holes in said model profile, resulting in a design program will be able to set the profile of the bottom sole of the set of holes that must be drilled through the location of the set of holes and a three-dimensional profile model. The profile of the face may include at least one curved portion which defines a curved contour mining, which must be formed, and at least one essentially flat portion of the sole of the set of holes. Finally, at the profile of the face will be posted endpoint holes. Almost the shape of the face may resemble the shape of a bowl, but for the sake of clarity in this application it is referred to as "essentially flat part.

The main idea of one possible implementation includes designing the layout of holes for mining, which includes a curve of small radius. In this case, the profile of the bottom set of holes, when browsing in the direction of set of holes, contains a portion of the side profile and essentially flat part on the bottom set of holes.

The main idea of one possible implementation includes designing the layout of holes for the nuclear biological chemical (NBC production, includes curvilinear profile of the roof. In this case, the profile of the bottom set of holes, when browsing in the direction of the bore-holes, contains part of the profile of the roof and essentially flat part on the bottom set of holes.

The main idea of one possible implementation contains a supply engineering program the pre-defined three-dimensional model of the profile of excavation, which must be drilled, and specifying the location of the set of holes in the model profile through the coordinate labels. Coordinate label set as a distance from a predetermined reference point, for example, starting from the initial point of excavation.

The main idea of one possible implementation contains the target point of the first holes in the plane on the bottom set of holes. After that, the holes that go beyond a pre-determined set of holes, shorten, while the endpoints of these recesses is placed in the intersection of the bore-holes and profile of the face.

The main idea of one possible implementation contains the target point of the first holes in the plane on the bottom set of holes. After that, the layout of boreholes modify, transferring endpoint of holes in predefined profile of the face with saving the coordinates of the initial point and the end point of the holes in EmOC is the making of the navigation plane, that is, the x and z coordinates of the end points are left unchanged. Instead, y coordinates of the end points are changed. Similarly guides the corners of the holes change.

The main idea of one possible implementation contains the target point of the first holes in the plane on the bottom set of holes. After that, the layout of boreholes modify, transferring endpoint of holes in predefined profile of the face with the original directions of the holes and save the coordinates of the end points in the direction of the navigation plane. In other words, the coordinates x and z endpoints are left unchanged, but the y coordinates are changed. Similarly, the starting point of the holes on the navigation plane change.

The main idea of one possible implementation is that the designer manually sets the display design of the computer or control unit rig the shape of the sole set of holes. After the shape of the sole of the set of holes was designed, relevant data, i.e. the profile of the face, is introduced into the design of the computer to design the layout of the holes. The display may present a set of holes in the desired projections, such as xz projection in the direction of drilling, and in the top view, that is, xy-projection. The project is iravozna the program may also contain a tool section, through which the designer can cut a set of holes in the planes of the section. After this, the designer can specify separately for each plane of the section profile of the face, using straight lines and round arches. Using these straight lines, circular arcs or lines similar to the shape specified by the user, the desired shape is cut out for a set of holes in different section planes, and when the data plane of the section will unite on the design computer, you will receive a three-dimensional profile of the face. This application can be used, for example, when there is only a technical drawing on paper, and no three-dimensional electronic model for mining, which must be performed.

The main idea of one possible implementation is that the existing arrangement of holes can be modified through the provision of engineering program a new profile slaughter or provide new theoretical profile of excavation excavation and location of set holes. In this case, the design program may determine the new locations of the end points of the holes and to update other data on the locations of the holes.

The main idea of one possible implementation includes designing the layout of the holes on proektirovok the second computer, located away from the mine workings and layout of the holes on the control unit drilling rig for drilling.

The main idea of one possible implementation includes designing the layout of boreholes or its modification in the control unit of the drilling rig.

The main idea of one possible implementation includes designing the layout of holes for the so-called inclined face first in the navigation plane, and then modify the schema so that the endpoints of the boreholes will be located on the desired profile of the face, which is at an angle to the navigation plane. The designer can enter the profile shape of the face in designing a computer, for example, in the form of angular data between the navigation surface and a sloped bottom or in the form of distances. In alternative, you can appreciate the previous form of an inclined face with a laser, for example, to transmit measurement data to design the computer and to modify the layout of the holes in the navigation plane so that the inclination of the face in a new set of holes will remain essentially the same as in the previous set of holes. The inclined face may be used, at least after the first sinking of the so-called rail tunnels, which extend with the help of a set Spyro is, which must be laid outside of the guide tunnel. In this case, the bottom set of holes that need to be routed outside of the guide shafts, can be tilted so that it is most profound on the boundary wall of the guide tunnel. Due to this more easily rock collapses toward the guide tunnel. In addition, in order to increase the strength of the excavation may require the use of an inclined face.

The main idea of one possible implementation is that the design of the computer modifies the layout of the holes, designed in the navigation plane, simulating the inclination of the sole set of holes. Modeling can be realized by means of the auxiliary plane, which design the computer sets the location and direction of which simulates the difference in directions between the navigation surface and the bottom of excavation.

The main idea of one possible implementation is that when the locations of the boreholes modified to the inclined face, bore-holes, designed in the navigation plane, is transferred in the direction of the desired profile of the face with maintaining the guides of the corners of the holes, and x and z coordinate of the end point. Thus y coordinates of the endpoints of change is fast, when they will be posted in the profile of the face. The y coordinate of the starting points of the holes also change accordingly. After migration, the boreholes included in the layout of the holes, continue, however, from their starting points to the navigation plane in the direction of the bore-holes. In this case, the starting point of each hole is shifted back to the navigation plane, but in a new location, keeping the new coordinates.

The main idea of one possible implementation is that for the design layout of boreholes program product is loaded into designing a computer drive or storage media such as pen drive, floppy disk, hard disk, network server, etc. while executing the software product in CPU design computer etc. performs the operations described in this application is intended for the design and modification of the layout of the holes.

DETAILED DESCRIPTION of SOME embodiments of the INVENTION

Figure 1 shows a drilling rig 1, which contains the movable chassis 2, one or more drilling shafts 3 and drilling units 4 located at the drilling shafts 3. Drilling block 4 contains the boot device 5, whereby it may be moved a mountain Boer 6. Boot device 5 may include guides and loading mechanism to move the mountain Boer 6. The drilling unit 4 further comprises a tool 7, through which the shock pulse generated by the percussion device of mining borax, is passed to the breed, which must be drilled. Drilling rig 1 also contains at least one control unit 8, which is arranged to control the actuators included in the drilling rig 1. The control unit 8 may be a computer the ROM or the like and may contain a user interface with displays and controls for the delivery of commands and data to the control unit 8.

As a rule, for drilling of each set of holes design scheme 9 blast-hole, such as, for example, the diagram shown in figure 2, which specifies, at a minimum, the location and guides the corners of the holes that must be drilled, in the coordinate system of the layout of the holes. In addition, scheme 9 blast-hole can determine the length of the holes that must be drilled, or the length can be determined through source locations and endpoints holes. The location of the holes can be defined by the coordinates of its starting point and end point or in the alternative on the basis of the initial location, the guide angle and length. The locations of the holes can be designed remotely, for example, in the office 10, where it can be stored on a medium such as a flash drive or disk, or it can be transmitted directly over the connection 11 of the transmission data to the control unit 8 of the rig and stored on storage media such as hard disk or floppy. In the alternative design and editing diagrams 9 blast-hole can be realized by the control unit 8, for example, in the cab 12 of the drilling rig 1. In addition, the existing layout of the holes can be edited on the rig floor and the outside of the site. Designing and editing diagrams 9 blast-hole are computerized procedures, and are usually repeated many times. Designing a program is executed on a design computer 13, the control unit 8 and the like, while the designer's works in cooperation with the design program and enters the required data, making the choices and controls the process of design. During the design of the existing part of the scheme can repeatedly be edited to achieve the best end result.

After the layout of the holes is designed, it can be loaded into the control unit 8 of the rig and then executed. Designed boreholes drilled at the rock 15, lay charges and produce erosion. From rocks 15 is separated rock material in an amount corresponding to the desired set of holes, then the rock is transported from the site. After that are drilling new holes for the next set of holes according to the new scheme 9 blast-hole.

Figure 2 shows a scheme 9 blast-hole, which can contain many holes 16 located in many of the nesting rows 17-19. External number of the recesses is the final profile 17, which defines the outer contour of the set of holes that must be drilled. In addition to the rows 17-19 I hate the ditch, scheme 9 blast-hole can contain a group of recesses 20 located in part between the inner row 19 holes and undercut 21. The undercut 21 is arranged to generate the initial space when blasting, which can be uncovered other parts kit bore-holes during the blasting. When designing the layout of boreholes to consider the technical details relating to explosives, for example, when determining the interval between the holes and the distance between rows of holes.

Figure 3 illustrates a schematic top view of the positioning of the set of holes 22 relative to mining 23. Excavation 23 may contain a predetermined axial line 24 and theoretical external circuits 25 and 26, shown later in figure 4 and 5. Excavation 23 may further comprise a point 27 located on the centerline 24 with mutual intervals. Customers ordering the mining and production of 23, can pre-define the outer contour of the excavation, a theoretical profile of the excavation, the location of the centerline 24, and the coordinates of the points 27. Each point 27 has a specific coordinate label 28, which indicates the depth of excavation 23 in this location from a reference point. Coordinate label 28 can be given, for example, in meters from the starting point of excavation. Coordinate label moget be used in the conduct of the drilling rig to the drilling site. On the basis of the coordinate of the label 28 can determine the location of the navigation plane N in the xz direction, after which the scheme 9 blast-hole is placed on the navigation plane N. in Addition, the coordinate of the label 28 can be used when designing the layout of the holes. Namely, by means of coordinate labels 28 can provide design program data relative to the location of the set of holes 22, which must be designed in the mine workings 23 thanks also ask the profile of the face of the above-mentioned set of holes.

Figure 4 illustrates the profile of the part 23a between the coordinate labels 180 and 195 in the mine workings 23 figure 3, which shows that the excavation has a curved outer contour, in this case, the circuit 25 of the roof. In addition, excavation may contain a side profile that includes a curved portion, or they may be formed in some other way. Excavation may thus have a three-dimensional shape, that is, it may be a so-called three-dimensional space. Location coordinate labels 180, 185, 188, 192 and 195 is indicated by the dashed lines. The navigation plane N scheme 9 blast-hole may be located in the set of holes 22, at the point specified coordinate label 188. Starting at point 29, the hole is in can be located in the navigation plane N. Some of the endpoints 30 of bore-holes can be located in the plane on the coordinate label 192, and some of the endpoints 30 will be placed on a curved contour 25 of the roof. Therefore, the profile 35 of the bottom set of holes has a flat part 31a and a curved portion 31b. After entering the coordinate labels 28 and the outer contour 25 mining 23 design program design program allows you to automatically set the profile 31 of the bottom set of holes 22 and to place the end point 30 on the profile of the face.

As a rule, the starting point 29 and the end point of 30 boreholes are located in the plane. It is also possible to design the program to place all the initial point of the first 30 in the flat part on the bottom set of holes 22, in this case, the coordinate label 192, and only then cut the part of the bore-holes, extending beyond the curved contour 25 of the roof, at the point of intersection of the contour 25 of the roof and holes. You can then move the end point 30 of the borehole outside of the profile 31 of the face, to the starting point 29 in the direction of the hole, resulting in the depth of the borehole is reduced compared to the original length. Transfer is illustrated by the arrow 32 in figure 4.

Figure 5 illustrates a curve of small radius portion 23b between the coordinate labels 195 and 198 in the mine workings 23 figure 3. Mountain in the development of 23 can be delimited by lateral profiles 26a and 26b on both sides of the centerline 24. The side profiles 26, the circuit 25 of the roof and the corresponding theoretical outer contours can specify the three-dimensional shape of the excavation, however, they can be designed in advance by the customer or designer excavation, for example, using CAD software. The external contours of the excavation can be loaded into a design program for designing a layout of holes. In the situation of figure 5 the starting point 29 of the holes can be located in the navigation plane N in the coordinate label 195, and some of the endpoints 30 holes can be located in the plane on the coordinate label 198. In addition, some of the endpoints 30 is placed on the side profile 26a at the outer edge of the curve. Profile 31 of the bottom set of holes, thus, may include a flat portion 31a and a curved portion 31b. Also in this case, the design program may first be placed all endpoints 30 in the flat part, and then cut the holes at the points of intersection of the side profile 26a and holes. In the alternative design, the program can accommodate endpoint 30 directly in the curved portion 31b of the profile of the face.

6 is a display image design of the computer or control unit in the rig. Design program soda can in order to reap the tool section, with which the designer can cut the profile 32 of bottom excavation of one or more planes 33a-33c of the section. After this, the designer can observe the plane 33 cut in the desired projections.

Fig.7 shows the plane 33a-33c section in the xy projection. The designer can manually define the shape of the sole set of holes. The designer can define a separate profile bottom for each section plane, using straight lines and round arch or line-like shape, whereby the desired shape in different section planes cut for the bottom set of holes. After the necessary interpolation is executed for the parts between the planes of the section, data regarding the shape of the face combine to design the computer, resulting in a three-dimensional profile of the face that comes in a design program for designing a layout of holes. In this case, the designer, therefore, with the design of the program is a three-dimensional profile of the face.

Fig shows the bottom hole 34 in the mine workings, which is tilted in the xy direction, i.e. horizontally. In some cases, mining production is intentionally carried out so that the face was permanently tilted from one set of holes to another. The use of an inclined face 34 mo is et to be justified, for example, when drilling larger excavation is first made by the guide tunnel, which serves as a hole, in which at undermining calved adjacent faces. Therefore, in terms of arrangement of the holes adjacent to the guide tunnel, no special design shear. On Fig and 9, on the left side of the face, there is a similar guide tunnel, which extends in the y direction further than the bottom 34. In addition, the text in relation to Fig penetration on the basis of the guide shafts is described in more detail.

The navigation plane N can be placed so that it passes through the external point 35 inclined face 34. In the alternative it can be positioned for passage, for example, through an interior point of the face. The original location of the holes according to the drilling diagram placed in the usual way in the navigation plane N in the course of designing the layout of the holes. On Fig also noted limits A and B profile of penetration and profile 31 inclined face already covered set of holes and the desired profile 31b inclined face a new set of holes, and profiles 31a and 31b of the face have the difference in direction relative to the navigation plane N.

Fig shows how the tilt of the face 34 may be modeled with what omashu auxiliary plane M. First auxiliary plane M can be placed on the navigation plane N, with holes of a specific length, beginning with the navigation plane N can be transferred from the navigation plane N to the auxiliary plane M After this auxiliary plane M can rotate around an external point 35 of the face 34 in the direction of K such that between the navigation plane N and the auxiliary plane M is such a difference in the direction between the navigation plane N and the profile 31 of the face. The difference in direction can do in designing the program as data on angles or distances. Profiles 31a and 31b of the face can have the same difference in the direction that is inclined face may continue with the same slope or alternatively, the slope may be changed, resulting profiles 31a and 31b of the bottom are variables differences in direction. The holes transferred to the auxiliary plane M are shifted in the y direction during rotation. Figure 9 the original hole indicated by the position 38a, and moved the hole - position 38b. The holes 38 retain their original direction and length during the rotation. In addition, all other coordinates of the end points of the holes, except for the y coordinates remain the same. Thus, the end points of the holes correspond to the ex is gnome position within the limits A and B of the profile.

Fig.9 shows that the boreholes included in the drilling scheme can be further extended at its beginning in the direction of the borehole to the navigation plane N. In this case, each hole will have a new length between the end 30 and the starting point 29.

Figure 10 and 11 show the schema, which can be executed in the control unit rig and displayed on the display prior to drilling, or it can be simulated by projecting the computer after designing the layout of the holes.

For the design of mining production, which should be carried out, provide pre-defined theoretical outline and valid boundaries A and B of the profile, and the end points of the holes that must be drilled in the destination profile 17, that is, the end recesses, must get to the part between them. If the drilling end begin deepening the internal boundary of A profile, the starting point of the borehole will be a shortage of cross-section generation. If the end point of an end recess is located outside the external borders of the B profile, erosion will cause a separation of more species than planned, that will bust cross-section generation. The shortage and bust section generate undesirable, because in this case, excavation, which is to be held is on, will not satisfy the statutory requirements in size and quality.

Figure 10 shows the display of the rig a situation in which the loading device 5 located outside the limits A and B of theoretical profile of the end of excavation for drilling cavities in the terminal profile in such a way that due to the wrong starting point drilling may occur under section generation in the path of excavation. This mapping can be automatically presented to the operator of the rig, and, in addition, the operator can be prevented in another way about the upcoming situation. Having a warning signal, the operator can change the position of the boot device 5 manually to correct the situation. The position and direction of the boot device can be represented in the graphical display when moving and, therefore, the operator can easily observe the effect made the repair. This is a useful feature, especially if for one reason or another form of slaughter in mines does not correspond to the form, modeled in designing the program, resulting in the designed layout of the holes cannot be applied. Figure 10 and 11 continuous line depicts the hole 39a in the drilling process, and the dotted line 39c depicts a borehole, the length of which re is olivetta on the basis of the warning signal. From the point of view of penetration is the most advantageous, however, is the ability to control the location of the bore-hole 39a, on the basis of the warning signal, according to the hole 39b, depicted by the dashed line, resulting in the promotion of excavation will be greatest.

11 is a schematic depiction in xy projection of the situation, which must be shown on the display of the rig, when the loading device 5 is for drilling holes of the end profile at this location that the recess 39a, which must be drilled, beyond the limits A and B of theoretical profile of the excavation the excavation, resulting in the search section generation in the profile of excavation due to erroneous initial point of drilling.

Thus, the method of warnings about the likelihood of a shortfall or excess generation section may contain at least the following operations determine theoretical profile sinking output, which should be carried out, the minimum profile of penetration and the maximum profile of the excavation, and the operator will be notified if the start or end point of any deepening of the profile is outside the region bounded by the minimum profile and the maximum allowable is the first profile.

Fig-14 illustrate a case involving the separation of a large scheme of an arrangement of holes. When the locations of the holes designed for large mining 23, which must be carried out, you may want to split a large layout of boreholes into two or more smaller partial arrangement of holes. You may want to divide the larger scheme simply because of its large size or in some cases, you may need to perform driving along the lower parts of the low-quality rocks or restrictions on vibration. Typical excavation of large cross section, which can be selected separation schemes into smaller partial layout of boreholes include underground Parking, storage, shelters, large road and rail tunnels, etc. When drilling the bottom of a large excavation, drilling rig is usually placed separately for each partial circuit layout of boreholes. In addition, each partial layout of boreholes undermine separately in a pre-designed order, resulting in the partial space of the layout of the holes, which undermine the beginning, can serve as an opening for a partial arrangement of holes, undermining later. Thus, the shear and boreholes included in the schema, you must define the ü only for the partial layout of the holes, which undermine the beginning. In the alternative partial layout of the holes can be undermined in one cycle. In addition, the locations of the holes can be designed as if the holes all the big scheme of an arrangement of holes drilled per cycle. To complete the design of a large arrangement of holes may be, however, divided into partial layout of the holes.

To divide a large schema, you can define one or more dividing lines 40, which pass through the dividing points 41, which must be placed on the diagram. The location of the dividing lines 40 can be determined in connection with designing the layout of the holes, but you can also create a dividing point 41 at a later stage in the completed layout of the holes. In addition, the location of the dividing lines 40 are chosen freely, and their location can be edited at a later stage, as the locations of the holes.

Different types of lines, such as Sole 42, the Wall 43, the Roof 44 and a Free 45 can be defined in a partial arrangement of holes. Fig and 14 illustrate the application of lines of different types. Free line 45 can be determined for a portion of the partial layout of the holes facing into the NWO is the same space previously passed a partial layout of holes and hence, therefore, the term "Free". In this case, design the program lays out the location of the holes 46, next to the wall, a given line of Free type on the designed distance E deepening from the Free line 45, and not on said line, as can be seen in Fig. Use the Free line 45 thereby facilitate the placement of the holes in the border area between passed and failed parts. Consequently, it is possible to avoid unnecessary drilling holes in the side parts already covered space.

On Fig shows a partial layout of the holes designed for the upper part of A, i.e. a kind of guide tunnel. The pattern of holes can be designed separately for each partial circuit layout of boreholes. On Fig shows designed partial schema B and C the location of the boreholes in which Free lines are present in parts of the side rail tunnel, which should be undermined in the beginning, that is, a partial diagram of A blast-hole.
