The technical FIELD TO WHICH the PRESENT INVENTION

The present invention refers broadly to a method and device for the production of materials in underground conditions.

PRIOR art

At the present time for the production of materials in underground conditions, for example, coal from coal seams, using a large number of diverse ways. Usually constructed tunnels, which can be supplied with numerous branches, providing access to the extracted materials. The tunnel is used to move workers and mechanisms when removing material. Therefore, the tunnels must fasten with anchor shoring or other support elements to ensure safe passage of people and mechanisms. Further, the tunnels have a large enough height and width to work and mechanisms could pass through them fairly comfortably.

The size of the tunnels also affects the thickness of the layer of material, ventilation requirements, the type of extraction, mining conditions, and other parameters. Typically the tunnels have a width of about 5-6 m, and a height of 2-4 m

Examples of methods of mining coal in underground conditions include methods of production, as “Lava”, “Shield and support, and to a lesser extent “Wongawilli”.

One of the greatest articles C is spending in the construction of tunnels, such as "production", under the earth, is necessary for the maintenance tunnels. Therefore a limiting factor in the economic success of the majority of underground tunnels is the ratio of a secure part of the tunnel to the extracted materials. The known methods are not advantageous in this sense, there is a need for technological development.

A SUMMARY of the PRESENT INVENTION

The present invention provides a first method of production of the material in underground conditions. The method consists of the following steps.

The location of structures within or adjacent to underground production so that this structure provided a reactive effort, when the cutting head is pushed in the direction of the material by means of the group of rigid elements associated with the structure, underground development thus suitable for the movement of people and transport mechanisms, and retrieve material;

the placement of the cutting head and a series of rigid elements so that the structure provided reactive force when pushing the cutting head in the direction of the material through a series of rigid elements; and

the formation of multiple parts of the branches of the tunnel, deepening into the material.

Step formation of multiple parts of the branches of the tunnel usually includes:

forming the first is part of the branch tunnel through the cutting head and the group of rigid elements; and after that, forming the second part of the branch of the tunnel, and the promotion of the rigid elements of the first part of the tunnel in the second part of the branch tunnel during the formation of the second section of the branch tunnel to promote the rigid elements in the second part of the branch of the tunnel.

Moving rigid elements usually involves moving rigid elements across the output.

The first and second parts of the branches of the tunnel can go from one part of the production. Alternatively, the first and second parts of the branches of the tunnel can go from opposite sides of manufacture.

The first and second parts of the branches of the tunnel can be formed by using the first and second cutting heads, respectively.

Step location patterns may include the location of the first and second structures within or adjacent to underground production so that the first and second patterns provide reactive efforts, while pushing the cutting head in the direction of the material through a series of rigid elements connected either with the first or with the second structure.

The step of positioning the cutting head and a series of rigid elements may include repositioning of the cutting head and a series of rigid elements in parts of the branches of the tunnels.

At least one of the parts formed branch tunnel about what commonly is more than 50 meters

Each rigid element is usually represented by a plot of rigid beams, such as plot hard “pushing beam, and, therefore, a series of rigid elements is usually a series plots beams.

The method may also include the step of forming the underground tunnels.

The material is usually developed by the education parts of the branches of the tunnel so that people do not need to be at least the greater part of the length of the formed parts of the branches of the tunnels.

In one particular example implementation, the method is performed so that part of the branches of the tunnel are formed by extraction of material without passing people in parts of the branches of the tunnel. Usually in parts of the branches of the tunnels you want to place only a series of rigid elements, the cutting head, and related machinery and consumables.

In one particular example implementation of the present invention, at least one part of the branch of the tunnel, and usually all the parts covered branches of the tunnel are formed without any supporting elements or rods.

In the framework of the present description, the word “core” (and its variants) is used to denote the steel elements that are installed to provide proper support to the surface of the tunnel, such as the development, in the underground the th environment.

At least, most of the formed parts of taps tunnels are longer than 100 m, 200 m, 300 m, or even more than 500 m In one specific implementation of the present invention all parts are covered branches of the tunnel has a length of more than 100 m, 200 m, 300 m, or even greater than 500 m

The material is usually part of the layer of material, such as coal seam.

Part of the branches of the tunnel usually form in the direction transverse development.

In one example, the step for forming multiple parts of the branches of the tunnel includes the redistribution patterns in the development after the formation of at least one part of the branch of the tunnel so that it can be formed in a part of the branch tunnel, starting from the other side of the tunnel. Further, the step for forming multiple parts of the branches of the tunnel usually involves lengthening, moving in the opposite direction and repositioning of a series of rigid elements. Additionally, the step for forming multiple parts of the branches of the tunnel usually includes transport excavated material to a remote location.

Further, the output from which further deepened part of the branches of the tunnel may be the first generation, and the method may include forming the second generation. The second output can be connected with a lateral part of the PE the howling develop so that series of rigid elements can move through part of the second generation in the direction of the first generation and to overlap with the first generation. Part of the branch of the tunnel may be conveniently formed from the first generation so that a separate rigid elements are moved across the first generation to extend a series of rigid elements used from the part of the branch of the tunnel.

For example, the second output may include the outgoing angle of the plot, which can be formed so that the material is between the first and second generation. In one example, the second output includes a part located parallel to the first generation.

The method may also include removing material between the first and second workings, usually by forming the first part of the branch of the tunnel, and then forming a second adjacent parallel side branches of the tunnel. The method may include reinstalling the cutting head and at least some rigid elements for positioning generally parallel to the previously formed branch tunnel. Further, the method may also include removing material from either of two sides of the first generation.

A series of rigid elements can be attached to the structure, either directly or indirectly through, the edge is her least one element, such as the connecting element.

The method generally includes forming part of the branches of the tunnel at a speed exceeding 10 m, 20 m, 30 m, or even greater than 50 m per hour.

The method typically includes the formation of multiple adjacent parts of the branches of the tunnel. Adjacent portions of the branches of the tunnel can be divided wall parts. As a variant, formed part of the branches of the tunnel may include at least some parts of the branches of the tunnel, not separated by wall parts, and together forming a part of the branches of the tunnel width.

The method in accordance with one variant of implementation of the present invention has significant commercial advantages. Due to the fact that usually there is no need for access to the generated parts of the branches of the tunnel, it is usually not necessary to fasten the branch tunnel to the security part of the branches of the tunnel beams or similar elements, resulting in much lower costs. Further, due to the fact that usually do not need to secure the parts of the branches of the tunnel, the average speed is considerably increased, and the material can be extracted more efficiently. Additionally, you can follow the changes of the reservoir, just changing the direction of forming one or neskonchaema branches of the tunnel, or formation of one or more parts of the branches of the tunnel on slightly different than the production level.

Output can be represented by one of the many generated workings of which formed part of the branches of the tunnel. For example, it is possible to form at least two mainly parallel openings, and the material located between at least two workings, can be extracted by forming parts of the branches of the tunnel from any of these at least two openings. The method may include forming parts of the branches of the tunnel from one of the openings in the direction of the adjacent generation, until it reaches the end part of another part of the branch of the tunnel. Material between at least two adjacent workings can be extracted in the process of forming multiple parts of the branches of the tunnel from any of the at least two adjacent openings.

The method typically involves increasing the length of a series of rigid elements. For example, the method may include adding rigid elements to the series, and thus increasing the length of a series of rigid elements.

The method may include pipeline transportation of extracted material from the end part of a series of rigid elements by developing a remote distance. For example, a series of rigid elements may include not m is it one of the screw, transporting the excavated material from the cutting head on the pipeline.

The method may also include forming parts of the branches of the tunnel so that formed part of the branches of the tunnel go deep with any of the two parties, any or each output. For example, the method may include forming at least one part of the branches of the tunnel from developing in the first direction, for example along the layer of material, and then forming at least one further part of the branches of the tunnel in the second direction, generally opposite to the first direction.

The present invention provides the second aspect of the device for the production of the material in underground conditions, the device includes:

a series of rigid elements longer than 50 m;

- cutting head connected to an end part of a series of rigid elements to extract material;

the first and second patterns for placement in or near the adjacent underground development, the first and second patterns are placed so as to provide reactive load when pushing the cutting head in the direction of the material to extract the material through a series of rigid elements connected to either the first structure or the second structure for forming the first or second part of the branches of the tunnel, respectively; and

- pipeline to pipeline the second transport excavated material to a remote distance.

The device is typically organized to promote branching tunnel from developing and to have a length corresponding approximately to the length of the group of rigid elements.

Each rigid element is typically a rigid beam section, such as a hard section of the pushing beam, and, therefore, a series of rigid elements are usually represented by a series of rigid beam sections.

The cutting head may be arranged to extract the material from the end portion side of the branch tunnel through the cutting material, grinding or removing material otherwise.

A series of rigid elements typically include rigid elements, which can be removed or inserted to adjust the length of the series of rigid elements. For example, a single rigid element can be 2 meters or more in length. The group of rigid elements may be no longer than 100 m, 200 m, 300 m, or even 500 m or more.

A series of rigid elements may be connected to the structure, either directly or indirectly through one or more element.

A series of rigid elements typically includes at least one auger, typically the group augers to transport excavated material from the cutting head on the part of the conveyor. In one particular implementation of the present invention, at least one auger series W the resource elements used for the transportation of the extracted material in the structure, located in the development and pipeline, located in the structure.

For example, the first and second patterns may include connecting elements, which can be located in structures and patterns can include open bottom located above the conveyor. The first and second connecting elements are usually arranged for connection with the terminal part of the group of rigid elements, and can be arranged so that the extracted material was obtained from at least one auger rigid member, and was directed through the open bottom part on the conveyor. The connecting elements can also include an actuator for driving at least one auger, a series of rigid elements. Next, the connecting elements can be arranged to connect a series of rigid elements in at least two directions, which can be opposite to each other, so that they can form branching tunnels in at least two directions.

In the third aspect, the present invention provides a method of extraction of material from a mine face, the method includes the following steps:

- positioning patterns in the mine, and the structure is organized in such a way to attach a series of plots beams with a cutting head and to provide the reactive load, when the cutting head is pushed in the direction of the recoverable material for removing material;

- the formation of the first part of the tunnel by means of the cutting head and attached to the structure of the series of sections of rigid beams;

- removing sections of rigid beams and cutting head from the side of the first tunnel after the formation of the first tunnel;

- the beginning of the formation of the second tunnel during the extraction sites beams and cutting head from the side of the first tunnel; and

- moving plots beams from the first tunnel to the second part of the tunnel during the formation of the second part of the tunnel.

The first and second side sections of the tunnel is usually approximately parallel parts of the tunnel.

The method typically includes the formation of many parts of the tunnel so that the formation of separate parts of the tunnel begins at the time of extraction sites beams and cutting head from the previously completed portion of the tunnel.

The invention will be better understood from the following description of specific variants of realization of the invention. Description presented with reference to the reference drawings.

DETAILED description of the SPECIFIC variants of REALIZATION of the PRESENT INVENTION

Referring initially to figures 1 through 3, describes how the production of the material in underground conditions in accordance with the specific variant of realization of the present invention. For example, underground conditions can be represented in terms of a coal mine, and the material can be extracted from the coal seam coal mines. Alternatively, the material can be presented ore, or may be another type of material mined in underground conditions.

Figure 1 shows a graph illustrating the production method of the material in underground conditions. The method 100 includes a step 102, in which is formed an underground development to ensure the safe movement of people, machinery, and transportation of the extracted material. The generated output is usually in the high is at 2-4 m and a width of 5-6 m and fixed terminals and/or other appropriate supporting elements.

The method 100 also includes the step 104, on which the structure is located in the development. The structure is organized in such a way as to ensure the connection of the series of sections of rigid beams with a cutting head and for reactive loads, when the cutting head is pushed in the direction of the material to extract the material.

The method 100 includes a step 106, which is formed by many parts of the branches of the tunnel, increasing from developing in the direction of the material using a cutting head and a series of sections of rigid beams connected with the structure. In this embodiment implementation of the present invention, step 106 includes movement patterns in development after the formation of at least one part of the branch tunnel, extension beams with attached cutting head during the formation of each part of the branch tunnel, return and repositioning series plots beams with attached cutting head after forming each part of the branch tunnel and transport excavated material to a suitable remote location.

Formed part of the branches of the tunnel can be more than 100 m, 200 m or even more than 300 m in length. The material is produced by forming parts of the branches of the tunnel without the need for human presence in established parts of the branches is onnela.

Figure 2(a) presents a schematic illustration of generation 200, formed in the underground environment 202. Structure 204 is in the development of 200. Series plots beams 206 with a cutting head 208 is connected with the structure 204. Structure 204 is fixed in the formulation for reactive effort when series plots beams 206 are pushing the cutting head 208 in the direction of the end part formed branch tunnel 210. For reactive efforts structure 204 is fixed in the development of means of suitable jacks, resting in the lateral part of the generation 200. Further, the conveyor 212 is in development for the transportation of material removed by the cutting head 208, a remote territory.

In this embodiment, the implementation part of the branch tunnel 210 is formed without the mounting part of the branch tunnel 210 in any way. Specifically, the rods or any other structure supporting the rigid elements is not installed in a branch of the tunnel 210. Therefore, the part of the branch tunnel 210 is not suitable for the passage of people. However, the method 100 is performed in such a way that there is no need for people to be part of the branch of the tunnel 210. As part of the branch tunnel 210 is typically not secured by rods or something similar, the method 100 has significant advantages of the mi, because the material can be extracted very efficiently.

The method 100 may further include the step of increasing the length of the series of sections of rigid beams 206 by setting individual sections of rigid beams, which can have a length in increments of 2 or 3 m or more. Series plots beams 206 typically includes at least one, and typically two, screw sections, working to transport the extracted cutting head 208 material from the cutting head to the structure 204. The conveyor 212 is located so as to receive the excavated material from the series of sections of rigid beams 206 so that the extracted material can be transported to a remote location convenient way. Series plots rigid beam 206 can be 100 m, 200 m, 300 m, 400 m and even more than 500 m in length. Each individual plot rigid beams usually includes one or two screw parts. For example, every piece of rigid beams may include two parallel screw section.

Connection (not shown) is located in the structure 204. The connection is designed to make connection series plots beams 206 structure 204, and includes an open bottom portion, and an actuator for actuating the same or each series plots augers series plots beams 206. The deleted material is transported from the cutting head 208 through the series past the Cove beams 206, and then falls through the open bottom connection part on the conveyor 212.

The size of the parts of the branches of the tunnel depends on the requirements, such as the thickness of the layer of material. For example, each part of the branches of the tunnel may be, on request, 2-3 m or more in height and width. When part of the branches of the tunnel is completed, a series of plots beams 206 with a cutting head 208 is removed. The connection is made so that the series of sections of rigid beams 206 may be attached to the left side of the connection or to the right side of the connection. In the illustrative example, the structure 204 is then removed by a distance approximately corresponding to the width of the formed part of the branch of the tunnel 210. Cutting head 208 and the original individual plot series plots beams 206 then join the left side of the connection, and formed the first section of the second branch of the tunnel. After that inserted the following sections of rigid beams, and forming a part of the second branch of the tunnel, as shown in figure 2 (b). Figure 2 (b) shows the formed portion of the second branch tunnel 214 extending from the left side generation 200. For lengthening of the second branch tunnel 214 extends a rigid beam 206, piece by piece.

Figure 2 (C) illustrates another variation of the described embodiments present the th of the invention. In this case series plots beams 206 with a cutting head 208 were removed after formation of the tunnel 210, shown in figure 1 (a), and then structure 204 has been removed to a distance approximately corresponding to the width of the formed part of the branch of the tunnel 210. However, unlike the example illustrated in figure 2 (b), the cutting head 208 and a series of sections of rigid beams 206 are connected with the connection so that the second part of the branch tunnel is formed next to the original part of the branch tunnel 210, and the resulting branch tunnel has a width approximately twice the width of the original branches of the tunnel 210.

Multiple side branches of the tunnel can be formed from developing 200 as described, when it is mined material around generation 200. The person skilled in the art it is clear that part of the branch tunnel can be formed in any way. Further, the person skilled in the art it is clear that part of the branch tunnel can simultaneously be formed on one side only generate 200.

Figure 3 illustrates a further embodiment of the present invention. The left side of the illustration in figure 3 corresponds to the one shown in figure 2 (a). The second generation 300 was formed in the same way. The second generation 300 in this example is separated from and is the parallel development 200. Figure 3 shows a portion of the second branch tunnel 302 formed of developing 300 in the direction of the branch tunnel 210 so that both parts of the branches of the tunnel could connect. Part of the branches of the tunnel 302 have a width approximately double the width of the side branches of the tunnel 210, and were formed by first forming the upper portion of the side branch tunnel 302, then extract series plots beams 306 with a cutting head 308, extraction patterns 304, and forming the lower portion of the side branch tunnel 302. Thus, the material workings between 200 and 300 may be retrieved.

Figure 4 shows the diagram of a device for the production of the material in underground conditions in accordance with the specific variant of the embodiment of the present invention. The device 400 includes patterns 402 and 403, a series of plots beams 404 and 405, and the cutting head 406 and 407. In this embodiment, the implementation of a series of sections of rigid beams 404 have a length of about 300 m, and each individual section rigid beam has a length of approximately 2 m Series plots beams 405 have a length of about 4 m (or more, if the rigid beam is longer).

Series plots beams 404 and 405 are made so that their length may be increased or decreased by inserting or extracting individual plots beams are appropriate to estwenno. Next, a series of plots beams 404 and 405 include a series of screws (not shown) for transporting material extracted cutting heads 406 and 407 to the structure 402. In this example, each section beams includes two parallel screw sections inside sections of rigid beams and are made so as to form two groups of augers.

The device 400 also includes a connection 408 and 409, to which are attached a series of sections of rigid beams 404. Connection 408 and 409 include actuators to actuate groups screws. Connection 408 and 409 have an open bottom portion of the cutting head, such as a cutting head 407, transported the extracted material, and through which the conveyed material falls on the conveyor 411, which includes a chain conveyor, overhead conveyor, and panel conveyor. Conveyor 411 transports the excavated material at a remote distance.

Connection 408 and 409 is arranged so that the series of sections of rigid beams can be attached to the connection to the left or to the right.

For forming part of the branch tunnel 412 initially the first section of rigid beams series plots rigid beam attached to the connection 408. During the advance portion of the branch tunnel 412 individual sections of rigid beams from the series of sections of rigid beams 404 sequentially p is ramasutra part of the tunnel 410 in the newly formed part of the tunnel 412 and inserted in series plots beams 405. Thus is formed the second part of the branch tunnel 412, which may be 300 m in length and over.

Once forming part of the tunnel 412 is completed, individual sections of beams can be moved to the connection 409, and may be formed in the next part of the branch tunnel (not shown), generally parallel to the side of the branch tunnel 410.

The person skilled in the art it is clear that the device 400 may take many different forms. For example, a series of plots beams 404 does not need to go from the structure 402 at a right angle.

Now let us describe the method of production of the material in underground conditions in accordance with a further variant of realization of the present invention with reference to Figure 5-8. Originally part of the tunnel 500, 502, and 504 are formed and secured for safe movement of people and machinery. The device 400 described above and illustrated in figure 4, is formed in parts of the tunnel 500, 502 and 504 as shown in Figure 5. In this example, the device 400 also includes supporting front line of destruction 501 and 503, and a series of sections of rigid beams 404 are placed in parts of the tunnel 500 and 502.

A separate part of the beams is then attached to the connection 408, and on the right hand side of the tunnel 504 is formed the next part of the tunnel, using cutting goal is Cai 407. Structure 402 provides reactive efforts, sufficient to cutting head 407 could be pushed through in the direction of the wall material. The excavated material is transported from the cutting head 407 on the conveyor 411, transporting it to a remote distance. During the advance portion of the tunnel to the right of part of the tunnel 504, portions of the rigid beam 404 is moved from side branches of the tunnel 504 in the newly formed part of the branch of the tunnel.

Figure 6 shows part of the tunnel 512 right side of the tunnel 504 formed in a similar manner. Figure 6 shows a device 400 with a series of rigid beams 404, located in the newly formed part of the branch tunnel 512.

After forming part of the tunnel 512 patterns 402 and 403, and the conveyor 411 were extracted for a short distance in the direction of the open area portion of the tunnel 504, as shown in Fig.7. Now the next part of the tunnel is formed on the left side of the tunnel 504 by means of the cutting head 409. 7 shows only that formed part of the branch tunnel 514 extending from the left side, or the same part of the tunnel 504. During the formation of side branches of the tunnel 514, separate parts of a series of rigid beam 404 has been moved from the side of the branch tunnel 512 in the part of the branch tunnel 514.

Alternatively, a new part of the branching tunnel 514 may also be formed from the structure 403 using cutting head 413.

After forming part of the tunnel 514, the next part of the tunnel is formed on the right side of the tunnel 504. On Fig shown formed part of the tunnel 516. For forming part of the tunnel 516 parts of the series a series of rigid beams 404 were successfully moved to the part of the tunnel 516.

The person skilled in the art it is clear that it is convenient to form a large number of parts of the tunnel, and you can get the material in underground conditions. Next, the specialist clearly that described above and illustrated in Figure 5-8 method is only a variation of a large number of possible examples, arising from the essence of the present invention.

Another embodiment of the present invention describes a method for extraction of material from the stope mine. The method includes placing the structure in a mining face. The structure is designed to connect sections of the series of the rigid beam with a cutting head and to provide reactive efforts, when the cutting head is pushed in the direction of the material to extract the material. The method also provides for the formation of the first part of the tunnel using a cutting head and a series of sections of rigid beams connected with the structure and extract sections of rigid beams and cutting head from the first part of the tunnel after forming the first part of the tunnel. Further, the method includes the beginning formed the Finance second tunnel during the extraction sites beams and cutting head from the first part of the tunnel. In this implementation, the hard part of the beam can be moved from the first part of the tunnel in the second part of the tunnel during the formation of the second part of the tunnel. The first and second parts of the tunnel is usually mainly parallel to each other. This method further includes the formation of many additional parts of the tunnel so that the formation of separate parts of the tunnel begins at the stage of retrieval.
