Background of the invention

The priority of this application is claimed in the prior application for U.S. patent No. 60/704,285, entitled "System fields with a narrow berm", filed 01.08.2005, which is incorporated into this description by reference.

The technical field of the invention

The present invention relates generally to the mining industry, and more specifically, to the exhaust means of transportation for a device designed for continuous development of the field of such material as coal, in situ.

Description of current level of technology

Coal, formed from decomposed and compressed substances of vegetable origin, usually found in the layers located essentially horizontally, passing between layers of sedimentary rocks, such as limestone, Sandstone or slate. The main technologies used for mining of such coal, are the development of open and underground mining methods.

Opencast mining involves removal of material, known as vskryshnyj layer of soil that lies above the coal seam to expose the coal for its retrieval. In recent years in the United States opencast mining has increased in comparison with the development of underground mining. This was due to many factors, with the edit:

a) increased throughput of mining equipment, which is used to ground or an open field development;

b) lower the cost of field development open method compared with the development of the underground;

C) the best safety performance development open method in comparison with the development of the underground;

g) a higher percentage of coal when retrieving a large number of stocks in an open way.

However, opencast mining has its limitations despite these advantages. The main limiting factor is related to the depth of overburden soil layer. Once the coal seam reaches a certain depth, the volume of the Stripping layer which must be removed in order to reach the coal, just makes the opencast mining uneconomic.

When this occurs, large quantities of coal can remain in the ground. In order to achieve cost-effective production of coal, it is necessary to use other methods of field development. The use of underground mining in this case is usually very limited. This may be due to several factors, including weak supporting the roof, the small thickness of the reservoir and/or insufficient supply of coal, which could not justify bol is a major investment, a distinctive feature of the development of deposits by underground method.

Due to these observations, after conducting field development open method was frequently used method snegoborbe mining, in which the process of removing overburden soil layer becomes too expensive. To penetrate into the surface of the reservoir and coal mining under overburden layer of soil, use a large sakabatou machine. Mining nicobaricum way mostly very effective, providing a greater number of tons of production per person per day compared to any other method of extraction. In addition, mining nicobaricum method can be quickly put into operation and requires relatively low capital investment compared to the development of open and underground mining methods. Moreover, until now it was thought that the best way to work in relatively thin layers is mining nicobaricum method. In addition, mining nicobaricum method is more secure than the development of open-pit and underground methods. Thus, mining nicobaricum method can be used to effectively complement Ave is in the process of developing an open way and for the development of small deposits of coal, which otherwise would have had to throw.

However, mining nicobaricum method also has disadvantages. It provides a relatively low total coal production. The output of useful coal component for zone minerals, which is developing nicobaricum method, typically less than 35%. Part of the yield loss of useful component caused by the pillars of coal are left standing to support the overburden soil layer between adjacent drill holes. However, a large part of the deficit in power production due to the limited depth of drilling, which can be achieved even with modern equipment for cnacoboboboo drilling.

More specifically, with increasing depth of drilling requires a greater number of sections of a screw auger to transport the coal from the cutting head to the surface of the mined seam. Each section adds friction resistance when turning the auger drill a result of contact with the wall of the drilling hole. In addition, the longer the column Nicobarese sections, the greater the mass of coal transported by sections at any time. In the result, it should be noted that the depth of penetration of the auger drill dramatically increase electricity demand for snegoborbe machine.

Sredstv the e above observations wells drilled normal nicobaricum equipment typically have a depth of only about 46 m (150 ft); the depth of 61 m (200 ft) is rare. Of course, it is desirable in any way to increase this value, since it would essentially improve the intensity of coal extraction from the zone of production.

The system and method of mining, which were developed for this purpose is described in U.S. patent No. 5364171, 5261729 and 5112111. All of these patents are owned by the copyright holder of the present invention, and a full description of these documents is included here by reference. As shown and described in these patents and in figure 1, the system field development includes continuous miner M, intended for blasting method for cutting coal from a coal seam S. the Cut coal is supplied by the harvester m on the conveyor chain T, consisting of a number of modular conveyor sections U, serially connected to each other. This system allows for the development of deposits at depths exceeding 46-61 m, which is possible when using traditional equipment for development using screw Boers. In fact, it had been the depth of 457 m

Each conveyor section of the U rests on the wheels W in contact with the ground, with the possibility of following the harvester M in IU is e, as he moves into the reservoir S of coal. Exhaust means L transportation is also built into this system. It includes a conveyor mechanism for receiving and moving the coal discharged from the conveyor. Exhaust means L transportation also contains a guide to maintain the tail section of the conveyor chain T sections U, which will be added to it. In addition, a separate drive nodes is made, first, to promote /extraction conveyor chain with the combine, and secondly to attach a new pipeline sections to the conveyor chain. The advantage is that the system allows to be axed part way and move the coal from the Deposit without stopping even when the conveyor chain T is added to the conveyor section U. Therefore, this system not only provides significantly increased the recess of the area of occurrence, but operates more efficiently than Nicobarese equipment, and provides improved performance.

Although the system and method development are described in these patents have commercial success, length prom transportation (about 27 m (90 ft)) restricted their use. In particular, many existing berm adjacent to the facing surface of the ledge quarry, are not wide enough to accommodate vypusknoi means of transportation such length. The present invention relates to the exhaust means of transportation with a modified design, with reduced length (about 14 m), which also accommodates a modular conveyor section field development systems. Mostly this final means of transportation for the first time allows the use of a system of mining on a relatively narrow berms.

The invention

To achieve the above and other objectives and in accordance with the purpose of the present invention, as described in this document, the proposed new discharge means of transport for the system of continuous mining, comprising a modular conveyor sections which are joined together with formation of the conveyor chain. Exhaust means for transporting includes the main frame to maintain the last section of the conveyor chain. The main frame has a first side, through which the conveyor chain added additional sections, and a second, opposite direction. Cumulative pipeline is located on the main frame beneath the conveyor sections. Cumulative conveyor transports the collected material, obtained from the last section of the conveyor chain. In addition, the exhaust means of transporting mounted drive unit. Drive unit is used on the I election forward or output conveyor chain through developing layer. Discharge means for transporting contains overlapping located at least over a part of the main frame. The overlap is mounted, at least one cantilever support. This console support goes up adjacent to the second side of the main frame. Thus, the first side remains open to add additional sections to the conveyor chain.

Describing the invention more in detail, accumulating conveyor is a belt conveyor. Cantilever support may be of a design beam box-section. In addition, the console support can be made adjacent to the first end of the main frame. In one possible embodiment, the ceiling is supported by two vertical support columns adjacent to the second end of the main frame. The first one is on the first side of the main frame, while the second is on its second side. Exhaust means for transporting includes a discharge conveyor, located on the main frame adjacent to its first end. The discharge conveyor receives the collected material from the accumulating conveyor.

The final means of transportation may contain jacks supporting the main frame on the berm adjacent to the facing surface of the ledge career. Jacks can extend or retract in order to regulate the th inclination of the floor of the exhaust means of transportation for approval by the berm so to conveyor section freely rolled over from a flooring outlet means of transportation on the berm and into the mineral seam.

In accordance with an additional aspect of the present invention, a method for reducing the length of the exhaust of a vehicle to maintain a free space sufficient to accommodate a conveyor section with one of its sides. The method includes the step of installation of the covering of the main frame exhaust means of transport for console support.

In the following description illustrates and describes the preferred embodiment of this invention only by way of illustration, one of the methods most suitable for carrying out the invention. It should be understood that the invention may have various other options and some of its details may be capable of modification in various obvious aspects, without deviation from the invention. Thus, the drawings and description are to be considered illustrative in nature and non-limiting.

The following is a detailed description of the present preferred variant implementation of the invention, an example of which is shown in accompanying drawings.

A detailed description of the preferred option run

2 to 4 depict the proposed discharge means 10 transportation used in mining on a ledge career of this type, which is described, for example, in U.S. patent No. 5364171, 5261729 and 5112111 that belong to the copyright holder of the present invention. The final tool 10 includes a main frame or structural frame 12, which is a pillar of the "cumulative" conveyor 14 DL the collected material, preferably the tape type. The conveyor 14 receives the collected coal from the last section of the conveyor chain, which deepened in the proposed reservoir. Then the coal is transported up the inclined plane by means of the accumulating conveyor 14 to the unloading conveyor 16, is made at the rear edge of the tool 10. Unloading conveyor 16 is also inclined and can be used, for example, to move the collected coal to its destination, for example to the subsequent conveyor system used to deliver coal to the truck for transportation to the place of storage or further processing.

As shown in the drawings, the tool 10 includes a protective overlay 18. In the shown embodiment, the overlay 18 is attached to the main structural frame 12 by means of cantilever support 20 has a first or rear edge of the tool 10 transportation and two vertical support legs 22, 24 at the second, or front, edge of the outlet means of transportation. The first leg 22 passes upward from the first side of the tool 10, while the second leg 24 and cantilever support 20 pass upward from the second side of the exhaust means of transportation. The advantage is that the cantilever support 20 performs the function of overlapping support 18 and eliminates the need for TNA is Noah rack on the first side of the exhaust means of transport at its second, or rear edges. Accordingly, the first side remains open, providing the necessary space to accommodate additional conveyor sections on the deck 26 of the exhaust means of transport and lengthening the conveyor chain, deep in the proposed reservoir, at the same time minimizing the total length of the discharge means 10.

As best seen in figure 5 and 6, the cantilever support 20 may be made of two shaped plates 28, 30 of high-strength steel, located at the top and bottom. These two plates are connected to the two vertical edges 32, 34 of high strength steel with a receiving box-shaped profile type double I-beams with narrow shelves. Plate used for the manufacture of box-shaped profile cantilever support 20 can be manufactured, for example, with a material thickness of 19 mm

The frame 12 is based on a set of four jacks 36, located adjacent to the four corners of the tool 10 transportation. The jacks 36 can be actuated to raise the frame 12 from the berm and to tilt the frame 12 and the deck 26 to provide unrestricted movement of each conveyor section U with the outlet means of transportation on the berm and the bottom layer.

Outward away from the body of each Jack passes the node 38 of the extension brackets. Extension brackets 38 BL is used for fixing the position of the exhaust means of transportation on the berm Century More specifically, the legs 40 of the brackets 38 are in connection with the berm Century These legs 40 can then be attached to the berm steel poles or pipes up to 152 mm in diameter, which are located in the holes in the legs and go down into a hole in the berm Century

As shown in Fig.7 and Fig, the drive unit 42 is located on the frame 12 and is used for feed-forward or output back conveyor chain. In the shown embodiment, the drive unit 42 includes interacting cylinders 41 dual actuator mounted adjacent to each side of the frame 12, preferably below the level of the deck 26. As is known in the industry, each drive cylinder includes a lever 43 of the plunger, which acts upwards through the slot 39 in the platform 26 and is used to interact with the corresponding pin p on the conveyor section U to move the conveyor chain forward inside seam of coal or backward.

As shown in detail 7, the lever 43 of the plunger can be rotated into position push (figa), the position of the extraction (pigv) or reside in the interim, the transit position (figs), in which both fingers are on the same level with the deck 26 so that the lever 43 of the pusher can be carried out without entering in contact with the pin P is positioned on the conveyor section U. the Lever 43 of the pusher hinge anchor is mounted on a wheeled trolley 45, which moves along the guide rails 47. Each drive cylinder 41 with one end attached to the carriage 45, and the other, opposite end to the frame 12, for example, by pins 49 or pins 51.

Thus, it should be understood that the drive unit 42 is powerful enough to facilitate the movement of the conveyor chain and digging machine forward inside of the reservoir and back. This is a particularly important advantage, as in many areas of development, there is a soft sole, such as fireclay. Under these conditions, caterpillars regular mountain harvester tend to knock out a rut in the weak basis up until the "highest point" of the main frame of the mining combine not zavazna in the non-milled base material, located inside the track. Therefore, mountain harvester that is designed to work blasting method has a tendency to get stuck where the base is in a weak condition. The advantage of this invention is that the drive unit 42 provides in these conditions, traction, so that the continuous miner and the conveyor chain can be moved forward or backward in accordance with the necessity.

As best seen in figure 2 and figure 3, the overlay 18 is at the forefront of the rock shield 44 with hydraulic drive, which can be rotated so that the EOI is to Modestovich with the surface F of mineral formation. On the covering 18 may also be coil 46 for unreeling a power supply line of the harvester, designed for use by the production method, as the advancement of the harvester and conveyor chain inside of the reservoir. Similarly, on the covering 18 may also be coil 50 for unreeling a power supply line conveyor truck advancing conveyor chain inside of the reservoir. There is also an additional coil 48, 52 to a water supply line and the control line. Coils 46, 48, 50, 52 also bind the corresponding lines (not shown) as output a harvester and conveyor chain from the reservoir.

In the shown embodiment, the overlay 18 in place of a convenient location can also be the main hydraulic unit 54 of the hydraulic systems exhaust means 10 transportation and the electrical node 56 prom transportation. Cabin 58 operator can be performed approximately at the level of the deck 26 on the second side, where the operator can monitor the operation of the exhaust systems of a vehicle and adding a separate conveyor sections to the conveyor chain.

When promoting the harvester and conveyor chains in the layer of the rear section of the conveyor chain approaches the front edge of the tool 10. When this happens, the operator uses pogruzochnaya, to raise additional conveyor section located near the berm. This loading device is then used to first move this additional conveyor section U, and then put it on the flooring 26 immediately behind the rear section of the conveyor chain. The advantage is that essentially L-shaped cantilever support 20 on the rear edge (or both edges) means 10 eliminates the need for hours on the first side, so that there's space for the location of the next conveyor section U on the floor 26 by means of the loading device. The advantage is that the lack of support columns on the first side and on the rear edge of the discharge means 10 transportation allows you to do this means a shorter, which, however, still provides the ability to add conveyor section. For example, the outlet means of transport length of only about 14 meters can be used to accommodate a conveyor section with a length of 9 meters, while at the final means of transportation 18 meters in length, can accommodate conveyor section length of 14 meters. The advantage is that as the tool 10 can be made shorter, the proposed system development fields can be used in areas with shorter and berms.

Once the new pipeline section U posted on the flooring 26, attached to the rear conveyor chain. Then the conveyor chain moves forward on the length of the conveyor section before the process is completed, to add another conveyor section. It should be understood that while adding the conveyor sections of the coal moves continuously. More specifically, first, the coal is moved from the last section of the conveyor chain to the accumulating conveyor 14, and then to the discharge conveyor 16. When the conveyor chain is attached a new conveyor section, the coal is moved from it either directly to the discharge conveyor, or to the far end of the accumulating conveyor, and then to the discharge conveyor. Accordingly, the continuous development of the field.

In one possible embodiment, the main frame 12 of the tool 10 consists of two groups arranged one above the other tubes of rectangular cross-section on each side of the belt accumulation conveyor 14. These beams consist of pipes with dimensions 30.48 cm × 50.8 cm × 1.27 cm, welded at the top of the pipe with dimensions 15.24 cm × 30.48 cm × 1.27mm see Beams are attached on both sides of the horizontal cross pipe of rectangular cross-section. The upper transverse tubes can be with dimensions 20.32 cm × 30.48 cm × 1.27mm see the Bottom is e transverse pipes can be with dimensions 15.24 cm × 25.4 cm × 1.27mm see Used from five to eight rows of these lateral pipes. Part of the Foundation, located on the sides of beams, consists of a cylindrical gusset plates of alloy plate with a thickness of 7.62 see These cylindrical scarves evenly distributed along the length of the tool 10. Powerful t sections placed between the gusset plates to maintain the drive unit 42. Scarves also support deck 26 with a thickness of 2.54 see This deck 26 supports the harvester and the first truck, when the system does not develop, and conveyor sections U during the development cycle. Cylindrical kerchiefs also form a structure on which are mounted four jacks 36, used for lifting and tilting mechanism. This framework also provides a mounting and support for the mounting flange and pre-installing the rear L-shaped cantilever support. As the tool 10 is assembled in modular form for ease of transportation, it should be understood that "setting handedness" prom transportation can be changed easily on the reverse by moving the attachment point of the cantilever support 20 on the opposite side of the main structural frame 12.

In summary, we can conclude that the application of the ideas of the present invention are obtained numerous benefits. The tool 10 may use the interference in the system to ensure continuous flow of cutting and moving coal from the surface of the reservoir so to make the formulation of the maximum. The advantage is that the cutting and moving of the collected material continues even when the conveyor chain added additional modular conveyor sections. The advantage is that the use of at least one cantilever support 20 eliminates the need for support columns overlap on one side of the exhaust means of transportation. Accordingly, it is possible to provide the necessary free space to accommodate the new pipeline sections on the flooring of the outlet means of transportation without the need to make this tool long to provide the necessary free space between the posts at each of its edges.

The above description of the preferred options for performing the present invention has been presented for the purpose of illustration and description. It is not intended to be exhaustive or to limit the invention described specific form. Obvious modifications or variations are possible in light of the above ideas. For example, while the illustrated embodiment of tool 10 contains only one cantilever support 20 can be performed multiple console supports. In addition, all of the vertical support columns on one side of the overlap, if necessary, can be eliminated is.

An embodiment was chosen and described to provide the best illustration of the principles of the invention and its practical application, thereby to enable any person skilled in the art to utilize the invention in various embodiments, execution and modifications in accordance with the specific intended application.
