[0034] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0035] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0036] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present application described here. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0037] The occurrence conditions of coal resources affect the choice of open-pit mining methods. According to the occurrence conditions of coal seams and the layout of working lines, they can be divided into two main categories: horizontal mining and vertical mining. Among them, vertical mining refers to a mining method in which the direction of the working line is consistent with the direction of the coal seam and it advances along the inclination. For horizontal mining, the working line is consistent with the inclination of the coal seam and it advances along the strike. Different mining methods have different application conditions and the resulting application effects. Since the vertical mining working line is consistent with the direction of the coal seam, the coal seam and rock strata steps are independently divided, while the horizontal mining working line has a mixture of coal and rock steps, especially all coal-bearing steps within the coal seam mining depth range are coal-rock mixed steps, which has a certain impact on the control of the coal-rock interface, especially the coal-rock mixing under blasting conditions. In order to reduce the impact of blasting on coal-rock mixing under horizontal mining conditions, it is necessary to propose a mining plan for horizontal mining working lines in open-pit coal mines. By controlling the number of mining widths of the mining belt at the coal-rock interface and adjusting the coal seam blasting and mining operation procedures, the longitudinal arrangement of the coal seam blasting working face under horizontal mining working line conditions can be achieved, and then the coal-rock mixing problem under horizontal mining conditions can be solved by the coal-rock mixed area mining procedure.

[0038] As introduced in the background technology, the quality of raw coal in the prior art is poor due to the mixing of coal and rock, and coal and rock will appear after blasting. In order to solve the above problems, the embodiments of the present application provide an open-pit coal mining method, an open-pit coal mining device, a computer program product and a coal mining operation system.

[0039] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0040] The method embodiments provided in the embodiments of the present application can be executed in a mobile terminal, a computer terminal or a similar computing device. Taking running on a mobile terminal as an example, Figure 1 FIG. 1 is a hardware structure block diagram of a mobile terminal for an open-pit coal mining method according to an embodiment of the present invention. Figure 1 As shown, the mobile terminal may include one or more ( Figure 1 Only one is shown in the figure) a processor 102 (the processor 102 may include but is not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA) and a memory 104 for storing data, wherein the mobile terminal may also include a transmission device 106 and an input / output device 108 for communication functions. It can be understood by those skilled in the art that Figure 1 The structure shown is only for illustration and does not limit the structure of the mobile terminal. Figure 1 More or fewer components as shown, or with Figure 1 Different configurations are shown.

[0041] The memory 104 can be used to store computer programs, for example, software programs and modules of application software, such as the computer program corresponding to the display method of device information in the embodiment of the present invention. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, that is, the above method is implemented. The memory 104 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some examples, the memory 104 may further include a memory remotely arranged relative to the processor 102, and these remote memories can be connected to the mobile terminal via a network. Examples of the above-mentioned network include but are not limited to the Internet, an intranet, a local area network, a mobile communication network, and a combination thereof. The transmission device 106 is used to receive or send data via a network. The above-mentioned specific examples of the network may include a wireless network provided by a communication provider of the mobile terminal. In one example, the transmission device 106 includes a network adapter (Network Interface Controller, referred to as NIC), which can be connected to other network devices through a base station so as to communicate with the Internet. In one example, the transmission device 106 may be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0042] In this embodiment, a method for mining an open-pit coal mine running on a mobile terminal, a computer terminal or a similar computing device is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0043] Figure 2 1 is a schematic diagram of a process flow of an open-pit coal mining method according to an embodiment of the present application. Figure 2 As shown, the method comprises the following steps:

[0044] Step S201, obtaining regional information of a coal mine, wherein the regional information includes at least one of information of a roof stripping area, information of a coal seam operating area, and information of a floor stripping area, wherein the roof stripping area is an area with rocks on the top of the coal mine, the coal seam operating area is an area in the coal mine that includes coal, and the floor stripping area is an area with rocks on the bottom of the coal mine;

[0045] Specifically, the coal mine area can be divided into three areas, namely, the roof stripping area, the coal seam operating area and the floor stripping area. The roof stripping area is the area that needs to be stripped, and there are a large number of rocks in the roof stripping area. The coal seam operating area has coal and is used for subsequent mining and loading. The floor stripping area is the area with rocks exposed after the coal in the coal seam operating area is mined and loaded.

[0046] Step S202, determining the mining sequence according to the above-mentioned regional information, so that coal is mined in accordance with the above-mentioned mining sequence, wherein the above-mentioned mining sequence is firstly performing stripping operations on the above-mentioned roof stripping area until the above-mentioned coal seam operating area is exposed, and then performing blasting operations and mining and loading operations on the above-mentioned coal seam operating area until the above-mentioned bottom plate stripping area is collected.

[0047] Specifically, the mining sequence is pre-established in this plan. The first step is to strip the roof stripping area until the coal seam operating area is exposed. The second step is to blast the coal seam operating area. The third step is to mine and load the coal seam operating area until the bottom stripping area is exposed.

[0048] Through this embodiment, the working line with mixed coal and rock is divided into different areas, and the operation sequence and content of different areas can be set. After the roof stripping area is stripped as a whole, the coal seam operating area is exposed, and then blasting operations are carried out on the coal seam operating area, thereby realizing independent operations of coal seams and rock seams, and independent penetration and blasting of coal seams, and reducing the probability of coal and rock mixing.

[0049] Specifically, under the conditions of horizontal mining in open-pit coal mines, the mining and stripping work line is arranged perpendicular to the ore body, moves along the ore body, and perforates and loosens the rock mass, and then the electric shovel cooperates with the single bucket truck for stripping. The section trench is arranged at the end of the open-pit mine, excavated perpendicular to the ore body, and pushed from one end to the other. In this way, the mine pit is gradually formed by cyclic advancement and deepening.

[0050] Specifically, perforation blasting can be carried out on the coal / rock / coal-rock mixed steps, and then the normal electric shovel can be used with a single bucket truck for mining and stripping. Figure 3 As shown, it includes the top roof stripping area, the coal seam operating area and the bottom plate stripping area.

[0051] Under normal horizontal mining conditions, the working line is arranged and advanced along the direction of the ore body. After reaching the boundary, it returns to advance to the next step or moves the equipment to the other end to continue advancing in the same direction of the next step. Under this condition, the amount of soil discharge is relatively uniform, and the height of soil discharge work in each time period is consistent.

[0052] In this plan, the working line advancement direction is consistent with normal horizontal mining, but when the lowest step advances to the coal seam, the advancement is stopped and the two lower steps are waited for to be advanced to the same position. During this period, the lowest step is waiting for the two lower steps to advance, resulting in accumulated soil discharge, which in turn causes delayed soil discharge. Subsequently, when the coal seam is advanced longitudinally, a large amount of soil discharge space is released, and at this time there is a rapid soil discharge phenomenon.

[0053] Specifically, this plan involves a working face controlled mining plan for coal-rock mixing control under the condition of a horizontal mining working line with inclined thin coal seams, so as to reduce the reduction in raw coal quality caused by coal-rock mixing, especially the coal-rock mixing problem after blasting.

[0054] Specifically, under the existing horizontal mining line arrangement conditions, if mixed drilling and blasting are used in the step perforation blasting process, it will inevitably cause coal-rock mixing and reduce the quality of raw coal at the coal-rock interface. If the coal seams are drilled and blasted separately, the inclination of the coal seams will affect the safe operation of the equipment. The existing horizontal mining line cannot solve the problem of reduced coal and rock quality caused by blasting in the coal-rock mixed area, especially under the conditions of inclined thin coal seams. To this end, a mining plan for the horizontal mining line of open-pit coal mines is proposed, which focuses on dividing the working line containing coal and rock mixtures into different sections, adjusting the coal seam drilling and blasting area to a longitudinal working face by controlling the number of mining belts and the advancement sequence in different sections, and adjusting the step division of the coal-rock mixed area through the mining procedure to achieve the longitudinal arrangement of the coal seam working face and independent drilling and blasting, thereby reducing coal and rock mixing.

[0055] Specifically, the adoption of this scheme can directly avoid the division of coal-rock mixed steps by adjusting the mining procedures, thereby reducing the reduction in raw coal quality at the interface caused by coal-rock mixed penetration and explosion, and can effectively realize coal-rock step mining and raw coal quality control under horizontal mining conditions (it can effectively increase the initial raw coal output and speed up the initial construction progress of the coal mine).

[0056] During the specific implementation process, after determining the mining order according to the above-mentioned regional information, the above-mentioned method also includes the following steps: obtaining the width of the mining belt, wherein the width of the mining belt is the construction width during the horizontal stripping operation; according to the width of the mining belt, performing stripping operations on the above-mentioned roof stripping area until stripping reaches the above-mentioned coal seam operating area.

[0057] In this plan, the width of the mining belt is predefined, and the stripping operation is carried out according to this predefined width until the coal seam working area is completely exposed. By pre-setting a reasonable mining width, the process of stripping operations can be optimized, unnecessary repetitive labor and waste of resources can be reduced, and mining efficiency can be further improved.

[0058] Specifically, the width of the mining belt can be determined according to geological conditions, equipment capacity, and mining efficiency, and can be determined according to the environment of the coal mine site. Those skilled in the art can set a suitable width of the mining belt.

[0059] Specifically, with the coal seam roof and floor as the dividing line, the horizontal mining work line steps are divided into three sections: roof stripping area, coal seam operation area, and floor stripping area. The coal seam operation area and floor stripping area are regarded as slow mining sections. According to the order of advancing the mining belts one by one, the roof stripping area is first stripped according to the mining belt width A, so that the step horizontal mining work step advancement width reaches iA (i = 1, 2, ... n), and within this width, the coal seam operation area of ​​this step is exposed along the strike direction,

[0060] Specifically, this direction is regarded as the working face of the coal seam operation area, and the steps of the coal seam within its width range are transformed into local longitudinal mining working faces under horizontal mining conditions. The coal seam steps are distinguished as coal-rock mixtures in the direction of the horizontal mining working line, and the coal seam steps here are independently set. This direction is used as the free face for coal seam penetration and blasting, and the coal seam penetration and blasting area is arranged with the coal seam exposed here, and the open incision is arranged at the exposed surface of the coal seam along the horizontal mining working line to carry out mining and loading operations on the coal seam. When the raw coal mining within the width range of iA (i=1, 2, ...n) is completed, the top plate stripping area operation procedure is repeated for the bottom plate stripping area until the bottom plate operation area is stripped and the advancement distance of the i mining belts of the horizontal mining working line is achieved, and then the above mining procedures are executed in sequence to complete the next i mining belt operations, and the cycle is repeated in sequence.

[0061] Specifically, Figure 4 and Figure 5 As shown in the figure, with the coal seam roof and floor as the dividing line, when the number of coal seams is n (2), the horizontal mining work line can be divided into n+2 (4) sections: stripping area, coal seam operation area, stripping area, coal seam operation area. First, the opening eye is arranged on the left side of the first mining belt, and then the stripping operation of the first mining belt is carried out according to the mining belt width A in the stripping area, and the stripping is carried out to the coal seam roof to expose the coal surface.

[0062] Specifically, Figure 6 and Figure 7 As shown, the second mining zone width A is stripped to the coal seam roof, and an opening is arranged on one side close to the coal seam and pushed back so that the exposed width of the coal seam step side reaches 2A.

[0063] Specifically, Figure 8 and Fig. 9 As shown, similarly, the cutting eyes are arranged from the left side, and the third mining belt width A is continued to be stripped to the coal seam roof, so that the exposed width of the coal seam step side reaches 3A.

[0064] In the specific implementation process, the width of the mining belt can be obtained by the following steps: obtaining width related information, wherein the width related information includes one or more of the blast pile width, rock loose coefficient, step height, blast pile height and blast pile shape coefficient; calculating the width of the mining belt according to the width calculation formula, wherein the width calculation formula is:

[0065]

[0066] A represents the width of the above-mentioned mining zone, b represents the width of the above-mentioned blast pile, and k s represents the loose coefficient of the rock, H represents the height of the step, H' represents the height of the blast pile, ε d Represents the above-mentioned burst pile shape factor.

[0067] In this solution, the width can be accurately calculated through the width calculation formula, further reducing unnecessary repetitive work and waste of resources, and further improving efficiency.

[0068] Specifically, three mining zones can be stripped out, with specific layouts as follows: Fig.10 shown.

[0069] Specifically, the blast pile width refers to the horizontal width of the rubble deposits produced by blasting. The size of the blast pile width will affect the distribution range and shape of the rubble deposits after blasting.

[0070] Specifically, the rock looseness coefficient refers to the degree of rock fragmentation after blasting, that is, the degree of looseness of the rock after fragmentation. The larger the rock looseness coefficient, the more thorough the rock fragmentation, and the higher the uniformity and stability of the crushed rock deposit.

[0071] Specifically, step height refers to the height of the step-like structure in the rubble deposit produced by blasting. The size of the step height will affect the slope and stability of the rubble deposit.

[0072] Specifically, the blast pile height refers to the vertical height of the rubble pile produced by blasting. The size of the blast pile height will affect the stability and accumulation shape of the rubble pile.

[0073] Specifically, the blast pile shape coefficient refers to the horizontal shape of the rubble pile produced by blasting. The size of the blast pile shape coefficient will affect the slope, stability and accumulation form of the rubble pile.

[0074] The unit of the width of the blast pile can be meter, the unit of the step height can be meter, and the unit of the blast pile height can be meter.

[0075] The calculation formula for the width of the burst pile is: b≤f(R wp +R xmax )-c, f is the excavator specification utilization coefficient, generally ≤0.9; c is the distance from the center line of the road to the bottom line of the blasting slope, generally 2 to 3m, R wp R is the standing horizontal excavation radius, m; xmax is the maximum unloading radius, m.

[0076] During the specific implementation process, after determining the mining order according to the above-mentioned regional information, the above-mentioned method also includes the following steps: obtaining the direction of the coal seam roof; performing coal seam drilling and blasting operations on the above-mentioned coal seam operating area according to the above-mentioned coal seam roof direction; arranging openings in the above-mentioned coal seam operating area after the coal seam drilling and blasting operations; and performing mining and loading operations on the above-mentioned coal seam operating area after the coal seam drilling and blasting operations according to the positions of the above-mentioned openings.

[0077] In this plan, the coal seam is broken up by blasting to facilitate subsequent mining and loading. Blasting operations are carried out in this direction to more effectively control the scope and effect of blasting and ensure that the coal seam can be fully broken up. Opening holes are one or more starting mining points or incisions set up in the coal seam operating area. This incision serves as the starting point for mining and loading operations, guiding subsequent coal mining operations and further improving mining efficiency.

[0078] Specifically, the direction of the coal seam roof can be measured and determined before coal seam mining. The direction of the coal seam roof has important guiding significance for subsequent mining operations. The penetration and blasting operation is to break the coal seam and part of the rock layer above it by blasting for subsequent mining. The penetration and blasting operation is carried out according to the direction of the coal seam roof, which can more effectively control the scope and effect of the blasting. The opening cut is one or more starting mining points or incisions set in the coal seam operating area. These incisions will serve as the starting point for mining and loading operations. After the opening cut is arranged, the coal mining equipment enters the coal seam operating area along the opening cut to carry out mining and loading operations.

[0079] Specifically, Fig.11 As shown in the figure, the direction of the coal seam roof is the direction of the blasting free surface, and the coal seam penetration and blasting operation is carried out in the exposed coal seam area. Fig.12 As shown, along the horizontal mining line, the coal seam exposed surface is arranged with cutting holes to carry out mining and loading operations on the coal seam. Fig.12 The box in the middle indicates the incision.

[0080] In some embodiments, after determining the mining order according to the above-mentioned regional information, the above-mentioned method also includes the following steps: obtaining the information of the above-mentioned bottom plate stripping area of ​​the Nth operation; using the information of the above-mentioned bottom plate stripping area of ​​the Nth operation as the information of the above-mentioned top plate stripping area of ​​the N+1th operation, and performing the N+1th coal mining operation according to the above-mentioned mining order.

[0081] In this plan, after each coal mining operation is completed, a new bottom plate stripping area will be formed, that is, the rock area originally below the coal seam. The bottom plate stripping area of ​​the Nth operation will be used as the top plate stripping area for the N+1th operation, which reduces the workload of repeated measurement and evaluation, improves mining efficiency, and helps maintain the continuity of mining operations.

[0082] Specifically, Fig.13 As shown, Fig.13The box in the middle indicates the opening of the cut. When the coal seam mining operation leaves a mining belt width, the next stage of horizontal mining and stripping work is carried out. The coal seam longitudinal advancement mining and rock stratum horizontal stripping work are carried out simultaneously, and the second and third mining belts to the bottom plate stripping area are stripped in turn. The three mining belts are fully stripped, and the expansion of the width of the three mining belts is completed. Through the above content, the stripping operation of the subsequent three mining belts is continued.

[0083] In some embodiments, after determining the mining order according to the above-mentioned area information, the above-mentioned method also includes the following steps: obtaining the positioning information of the coal mining equipment; determining the target area of ​​the current operation according to the above-mentioned mining order; determining whether the above-mentioned coal mining equipment is located in the above-mentioned target area for operation according to the above-mentioned positioning information, and obtaining a positioning result; when the above-mentioned positioning result indicates that the above-mentioned coal mining equipment is located in the above-mentioned target area for operation, determining that the above-mentioned coal mining equipment is operating out of bounds and generating an alarm message.

[0084] In this solution, the current position of the coal mining equipment can be obtained. If the coal mining equipment is not in the target area of ​​the current operation, it is considered that the coal mining equipment has crossed the boundary and an alarm can be issued to prompt the coal mining staff to avoid errors in the coal mining sequence, thereby ensuring better efficiency and accuracy of the coal mining operation.

[0085] Specifically, the coal mining equipment may be a coal mining machine, a conveyor, a hydraulic press, a crushing equipment, and the like.

[0086] In some embodiments, after determining the mining order according to the above-mentioned regional information, the above-mentioned method also includes the following steps: obtaining the coal mining speed; when the above-mentioned coal mining speed is less than a preset speed threshold, controlling the drainage equipment to operate so as to drain the above-mentioned coal mine.

[0087] In this plan, if the coal mining speed is relatively slow, it may be caused by excessive water accumulation. When there is a lot of water accumulation, the coal mining equipment cannot run at the predetermined speed and there will be certain obstacles. Therefore, if the coal mining speed is relatively slow, the drainage equipment can be controlled to drain water, so as to ensure the safety of the coal mining equipment and coal mining workers.

[0088] Specifically, the drainage equipment can be a centrifugal water pump, an axial flow pump, a submersible pump, etc. Of course, it can also be any other feasible equipment that can be used for drainage.

[0089] Specifically, the preset speed threshold may be 5 M / S, 3 M / S, 8 M / S, etc., and of course, may also be any other feasible threshold.

[0090] Specifically, the operation of the drainage equipment can also be controlled according to the bottom water level and the drainage volume. For example, if the bottom water level exceeds the water level threshold, or the drainage volume is greater than the predetermined drainage volume, more drainage equipment is added to perform drainage processing.

[0091] Specifically, during the stripping operation and when arranging the opening of the cutting eye, the opening of the cutting eye can be arranged on the left side, just like the direction of the mining sequence.

[0093] The following is an introduction to the open-pit coal mine mining device provided in the embodiment of the present application.

[0094] Fig.14 1 is a structural block diagram of an open-pit coal mine mining device according to an embodiment of the present application. Fig.14 As shown, the device comprises:

[0095] A first acquisition unit 10 is used to acquire regional information of a coal mine, wherein the regional information includes at least one of information of a roof stripping area, information of a coal seam operating area, and information of a floor stripping area, wherein the roof stripping area is an area with rocks on the top of the coal mine, the coal seam operating area is an area including coal in the coal mine, and the floor stripping area is an area with rocks on the bottom of the coal mine;

[0096] The mining unit 20 is used to determine the mining sequence according to the above-mentioned regional information so that coal is mined in accordance with the above-mentioned mining sequence, wherein the above-mentioned mining sequence is to first perform stripping operations on the above-mentioned roof stripping area until the above-mentioned coal seam operating area is exposed, and then perform blasting operations and mining and loading operations on the above-mentioned coal seam operating area until the above-mentioned bottom plate stripping area is collected.

[0097] Through this embodiment, the working line with mixed coal and rock is divided into different areas, and the operation sequence and content of different areas can be set. After the roof stripping area is stripped as a whole, the coal seam operating area is exposed, and then blasting operations are carried out on the coal seam operating area, thereby realizing independent operations of coal seams and rock seams, and independent penetration and blasting of coal seams, and reducing the probability of coal and rock mixing.

[0098] During the specific implementation process, the above-mentioned device also includes a second acquisition unit and a stripping unit. The second acquisition unit is used to obtain the width of the mining belt after determining the mining order according to the above-mentioned area information, wherein the above-mentioned mining belt width is the construction width during the horizontal stripping operation; the stripping unit is used to perform stripping operations on the above-mentioned roof stripping area according to the above-mentioned mining belt width until stripping reaches the above-mentioned coal seam operating area.

[0099] In this plan, the width of the mining belt is predefined, and the stripping operation is carried out according to this predefined width until the coal seam working area is completely exposed. By pre-setting a reasonable mining width, the process of stripping operations can be optimized, unnecessary repetitive labor and waste of resources can be reduced, and mining efficiency can be further improved.

[0100] In the specific implementation process, the second acquisition unit includes an acquisition module and a calculation module. The acquisition module is used to acquire width-related information, wherein the width-related information includes one or more of the blast pile width, rock loose coefficient, step height, blast pile height and blast pile shape coefficient; the calculation module is used to calculate the width of the mining belt according to the width calculation formula, wherein the width calculation formula is:

[0101]

[0102] A represents the width of the above-mentioned mining zone, b represents the width of the above-mentioned blast pile, and k s represents the loose coefficient of the rock, H represents the height of the step, H' represents the height of the blast pile, ε d Represents the above-mentioned burst pile shape factor.

[0103] In this solution, the width can be accurately calculated through the width calculation formula, further reducing unnecessary repetitive work and waste of resources, and further improving efficiency.

[0104] During the specific implementation process, the above-mentioned device also includes a third acquisition unit, a first processing unit, a second processing unit and a third processing unit. The third acquisition unit is used to obtain the direction of the coal seam roof after determining the mining order according to the above-mentioned regional information; the first processing unit is used to perform coal seam penetration and blasting operations on the above-mentioned coal seam operating area according to the above-mentioned coal seam roof direction; the second processing unit is used to arrange openings in the above-mentioned coal seam operating area after the coal seam penetration and blasting operations; the third processing unit is used to perform mining and loading operations on the above-mentioned coal seam operating area after the coal seam penetration and blasting operations according to the positions of the above-mentioned openings.

[0105] In this plan, the coal seam is broken up by blasting to facilitate subsequent mining and loading. Blasting operations are carried out in this direction to more effectively control the scope and effect of blasting and ensure that the coal seam can be fully broken up. Opening holes are one or more starting mining points or incisions set up in the coal seam operating area. This incision serves as the starting point for mining and loading operations, guiding subsequent coal mining operations and further improving mining efficiency.

[0106] In some embodiments, the above-mentioned device also includes a fourth acquisition unit and a fourth processing unit. The fourth acquisition unit is used to obtain the information of the above-mentioned bottom plate stripping area of ​​the Nth operation after determining the mining order according to the above-mentioned area information; the fourth processing unit is used to use the information of the above-mentioned bottom plate stripping area of ​​the Nth operation as the information of the above-mentioned top plate stripping area of ​​the N+1th operation, and perform the N+1th coal mining operation according to the above-mentioned mining order.

[0107] In this plan, after each coal mining operation is completed, a new bottom plate stripping area will be formed, that is, the rock area originally below the coal seam. The bottom plate stripping area of ​​the Nth operation will be used as the top plate stripping area for the N+1th operation, which reduces the workload of repeated measurement and evaluation, improves mining efficiency, and helps maintain the continuity of mining operations.

[0108] In some embodiments, the above-mentioned device also includes a fifth acquisition unit, a first determination unit, a second determination unit and a fifth processing unit. The fifth acquisition unit is used to obtain the positioning information of the coal mining equipment after determining the mining order according to the above-mentioned area information; the first determination unit is used to determine the target area of ​​the current operation according to the above-mentioned mining order; the second determination unit is used to determine whether the above-mentioned coal mining equipment is located in the above-mentioned target area for operation according to the above-mentioned positioning information, and obtain a positioning result; the fifth processing unit is used to determine that the above-mentioned coal mining equipment is operating out of bounds and generate an alarm message when the above-mentioned positioning result indicates that the above-mentioned coal mining equipment is operating in the above-mentioned target area.

[0109] In this solution, the current position of the coal mining equipment can be obtained. If the coal mining equipment is not in the target area of ​​the current operation, it is considered that the coal mining equipment has crossed the boundary and an alarm can be issued to prompt the coal mining staff to avoid errors in the coal mining sequence, thereby ensuring better efficiency and accuracy of the coal mining operation.

[0110] In some embodiments, the above-mentioned device also includes a sixth acquisition unit and a control unit. The sixth acquisition unit is used to obtain the coal mining speed after determining the mining order according to the above-mentioned regional information; the control unit is used to control the drainage equipment to drain the above-mentioned coal mine when the above-mentioned coal mining speed is less than a preset speed threshold.

[0111] In this plan, if the coal mining speed is relatively slow, it may be caused by excessive water accumulation. When there is a lot of water accumulation, the coal mining equipment cannot run at the predetermined speed and there will be certain obstacles. Therefore, if the coal mining speed is relatively slow, the drainage equipment can be controlled to drain water, so as to ensure the safety of the coal mining equipment and coal mining workers.
