Description

Technical Field

[0001] The present disclosure relates to the field of coal mine production, and in particular to a method and device for turning an open-pit mine, an electronic device and a storage medium. Background Art

[0002] Open-pit coal mines with zoned mining all have the problem of internal drainage balance during the transition period, that is, the internal drainage is tight in the early stage, and the internal drainage space is suddenly released at the end, resulting in the internal drainage yard not being fully utilized, the external drainage area increasing, and difficulty in reclamation at the end.

[0003] During the production period of the open-pit mine, the first mining area is turning to the second mining area, the land acquisition of the village is delayed, the coal seam is extended downward, and the inclination of the coal seam is increased. Under the influence of these unfavorable conditions, the coal seam in the southern part of the first mining area and the second mining area of ​​the open-pit mine has a large inclination, with a slope of 10° to 19°, and the working face is gradually transformed into a method of advancing from north to south and horizontal arrangement (horizontal mining). In the process of advancing the working face, multiple layers of coal and rock will cross on the same flat plate, and there are problems such as great difficulty in large-scale equipment selection, large loss of raw coal, low coal selection rate, and difficulty in exerting equipment efficiency; after the turn, the working line of the first mining area becomes shorter, and the horizontal arrangement length of the working line is only 500-800m. The length of the working line is shortened, the operation cycle of each link of the production is accelerated, and the short working line, large extension depth, narrow working face, and fast advancement production lead to the difficulty of connecting each link of the production, the difficulty of exerting equipment efficiency, the reduction of exposed coal, and the reduction of the economic benefits of the open-pit mine; and with the continuous advancement of the mining field, the transportation distance and height difference will still have a tendency to increase, resulting in a sharp increase in the height difference of the soil discharge transportation distance during the turn of the open-pit mine.

[0071] The following is a description of exemplary embodiments of the present disclosure in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0072] The following describes the method, device, electronic device and storage medium for open-pit mine steering according to the embodiments of the present disclosure with reference to the accompanying drawings.

[0073] Figure 1 A schematic flow chart of a method for diverting an open-pit mine provided in an embodiment of the present disclosure.

[0074] like Figure 1 As shown, the method comprises the following steps:

[0075] Step 101, obtaining the mine data of the target open-pit mine, and determining the steering treatment plan of the target open-pit mine according to the mine data; wherein the steering treatment plan at least includes the open-pit mine boundary, the working line layout plan, the dumping plan and the dumping field connection plan.

[0076] In the embodiments of the present disclosure, the present disclosure can be applied to the production process of open-pit mines with complex geological conditions. Specifically, the embodiments of the present disclosure do not limit the application scenarios of the present disclosure.

[0077] Among them, the mine data is data containing all parameters of the target open-pit mine, such as: the length of the forced pushing working line, the mining and stripping project volume, the earth-discharging space, the working face transportation route, the amount of material stripped from each flat plate, the location of the waste dump and the location of the waste dump of each mine in the mining group, etc. Specifically, the content of the mine data is not limited in the embodiments of the present disclosure.

[0078] The diversion treatment plan at least includes optimizing the mining procedure (determining the boundary of the open-pit mine), adjusting the work line layout (determining the work line layout plan), tilting the base to discharge soil (determining the discharge plan), increasing the capacity of the discharge yard (determining the discharge yard interconnection plan), etc. After the target open-pit mine is processed by various methods in the diversion treatment plan, the open-pit mine production can be continued, the discharge and transportation distance can be reduced, and the economic benefits can be improved.

[0079] Specifically, by optimizing the mining procedure, the effective internal drainage space can be increased and the tight situation of soil discharge space can be alleviated. By adjusting the work line layout, the comprehensive transportation distance, the corresponding transportation costs and the inclined push work line with lower impact on the electric shovel layout can be calculated, thereby reducing the drainage transportation distance. By tilting the base soil discharge, the soil yard discharge can be met, which effectively solves the problem of the rapid increase in the inclination angle of the bottom plate of the anticline coal seam and the limitation of the soil discharge space. By increasing the capacity of the soil discharge yard, the overall soil discharge cost of the open-pit mine group can be reduced and the economic benefits can be improved.

[0080] Step 102, based on the working line arrangement plan, arrange the oblique push working line at the first preset orientation of the target open-pit mine to obtain the arranged target open-pit mine, and set the target dumping yard of the arranged target open-pit mine based on the dumping plan.

[0081] In the embodiment of the present disclosure, the first preset direction is a user-selected direction, for example: the southeast of the target open-pit mine, the southwest of the target open-pit mine, etc. Specifically, the embodiment of the present disclosure does not limit the first preset direction.

[0082] Among them, the working line layout plan is to combine the amount of material stripped from each flat plate, the location of the waste dump, and the transportation route to calculate the comprehensive transportation distance, corresponding transportation costs, and the impact on the layout of the electric shovel, etc. of various layout plans, and finally determine the optimal layout plan of the working line that is pushed obliquely to the southeast among all the layout plans, that is, the layout plan with the highest economic benefits among all the layout plans. Regarding the layout of the oblique push working line, for example: the layout of the stripping working line in the southeastern mining area of ​​the first mining area, etc., by optimizing the layout of the stripping working line in the southeastern mining area of ​​the first mining area, and establishing a calculation model for the working line in the southeastern part of the mine pit to calculate the transportation distance of the mine pit, it is obtained that the transportation distance and transportation costs are saved after optimization, thereby increasing economic benefits.

[0083] The target dump can increase the dumping capacity of the target open-pit mine. The dumping plan is a plan determined by the data of the target open-pit mine, for example: the north side supported pseudo-inclined dumping plan, etc. By studying the inclined bottom plate dumping method of the target open-pit mine, the proposed dumping plan can increase the dumping capacity of the west inner dump.

[0084] Step 103, based on the dump interconnection scheme, the target dump is interconnected with other dumps to obtain a processed target open-pit mine; wherein the other dumps are dumps of other open-pit mines except the target open-pit mine.

[0085] In the disclosed embodiment, by interconnecting various spoil dumps, the spoil dumping problem of each open-pit mine can be comprehensively considered from the perspective of an open-pit mine group, and the spoil dumps of each mine in the mine group are uniformly planned. When an open-pit mine in the mine group has insufficient disposal space due to objective factors such as special geological conditions, consideration is given to formulating a spoil dump sharing plan to fully utilize the spatial resources within the mine group, use the internal spoil dumps of adjacent mines for spoil dumping, and use methods such as connecting spoil dumps and building intermediate bridges to shorten transportation distances and reduce the overall spoil dumping cost of the open-pit mine group.

[0086] Step 104, advancing the forced pushing working line from the second preset position of the processed target open-pit mine to the boundary of the open-pit mine, and performing a turning and horizontal mining process at the boundary of the open-pit mine.

[0087] In the embodiment of the present disclosure, the second preset orientation is a user-selected orientation, for example, the north of the target open-pit mine. Specifically, the embodiment of the present disclosure does not limit the second preset orientation.

[0088] When the second preset direction is the north of the target open-pit mine, the method of turning to horizontal mining of the target open-pit mine is to forcefully push the ultra-short working line in the north + realize the internal drainage in the north in advance, which can increase the effective internal drainage space in the north and alleviate the tense situation of the soil discharge space.

[0089] The present disclosure provides a method for turning an open-pit mine, which obtains mine data of a target open-pit mine, and determines a turning treatment plan for the target open-pit mine based on the mine data; wherein the turning treatment plan at least includes an open-pit mine boundary, a work line layout plan, a soil dumping plan, and a soil dumping yard connection plan; based on the work line layout plan, an oblique push work line is arranged at a first preset position of the target open-pit mine to obtain the arranged target open-pit mine, and a target soil dumping yard of the arranged target open-pit mine is set based on the soil dumping plan; based on the soil dumping yard connection plan, the target soil dumping yard is connected with other soil dumping yards to obtain the treated target open-pit mine; wherein the other soil dumping yards are soil dumping yards of other open-pit mines except the target open-pit mine; the forced push work line is pushed from the second preset position of the treated target open-pit mine to the open-pit mine boundary, and a turning and horizontal mining process is performed at the open-pit mine boundary. Compared with the related technologies, the embodiments of the present disclosure achieve the effects of ensuring the continuity of open-pit mine production, reducing the distance of discharge and transportation, and improving economic benefits by optimizing the mining procedure, adjusting the working line layout, dumping soil on the inclined base, and increasing the capacity of the spoil field.

[0090] In one implementable method of the embodiment of the present disclosure, when determining the steering treatment plan of the target open-pit mine according to the mine data, it is necessary to determine each strategy in the steering treatment plan separately, that is, it is necessary to separately determine the optimization of mining procedures (determine the open-pit mine boundary), work line layout adjustment (determine the work line layout plan), inclined base soil discharge (determine the soil discharge plan), soil dump capacity increase (determine the soil dump connection plan) and other contents. Therefore, in order to accurately and completely obtain the steering treatment plan, the embodiment of the present disclosure provides a flow chart of a method for determining a steering treatment plan, such as Figure 2 As shown, including:

[0091] Step 201, obtaining the length of the forced pushing line, the mining and stripping engineering volume and the earth-draining space contained in the mine data, and determining the boundary of the open-pit mine according to the length of the forced pushing line, the mining and stripping engineering volume and the earth-draining space.

[0092] In the disclosed embodiment, the open-pit mine boundary is determined by studying and analyzing the relationship between the length of the northern forced pushing work line, the mining and stripping project volume and the earth discharge space. For example, the 11 coal F12 fault is used as the boundary. At this time, the advancement plan for the target open-pit mine is an advanced advancement plan with the 11 coal F12 fault (the open-pit mine boundary) as the boundary, so as to quickly advance in the north and approach the boundary locally as a whole, thereby realizing internal discharge in the north, while the south is slowly advanced to make up for the insufficient production in the north. After the north is forced to the open-pit mine boundary, it is turned to horizontal mining to increase the effective internal discharge space in the north and alleviate the tense situation of earth discharge space.

[0093] Step 202: Acquire the working face transportation route data contained in the mine data, and determine the working line layout plan based on the working face transportation route data.

[0094] In the disclosed embodiment, the working face transportation line is abstracted according to the working line layout combined with the triangular characteristics, and a transportation distance model of the working face moving pit line under different working line layouts is established, and a transportation distance calculation method for different working line layouts is provided, which simplifies the design process. According to the established working face moving pit line transportation distance calculation model, combined with the amount of material stripped from each flat plate and the location of the waste dump and the transportation route, the comprehensive transportation distance, corresponding transportation cost, and the impact on the electric shovel layout of various layout schemes are calculated, and the optimal layout scheme is finally determined as the working line layout scheme among all the layout schemes. The optimal layout scheme refers to the layout scheme with the highest economic benefit among all the layout schemes.

[0095] The working surface distance of the working line that is not arranged using the working line arrangement scheme can be expressed by, but not limited to, formula (1):

[0096]

[0097] The working surface distance of the working line arranged using the working line arrangement scheme can be expressed by, but not limited to, formula (2):

[0098]

[0099] Step 203, obtaining the supporting force data of the inclined bottom plate and the end wall contained in the mine data, and determining the soil discharge plan based on the supporting force data.

[0100] In the disclosed embodiment, full use is made of the supporting force of the inclined bottom plate and the end sides, and soil is discharged obliquely with the two sides to form a stable triangular support structure. Combined with the grooves after blasting of the bottom plate, the obtained soil discharge scheme can effectively increase the stability of the soil discharge yard, thereby meeting the requirements of soil discharge in the yard and effectively solving the soil discharge problem in the anticline area.

[0101] Step 204, obtaining spoil dump data included in the mine data, and determining the spoil dump connection solution based on the spoil dump data.

[0102] In the disclosed embodiment, the soil discharge problem of each open-pit mine is comprehensively considered from the perspective of the open-pit mine group, and the soil discharge yards of each mine in the mine group are uniformly planned. When an open-pit mine in the mine group has insufficient discharge space due to objective factors such as special geological conditions, consideration is given to formulating a soil discharge yard sharing plan, that is, the soil discharge yard interconnection plan, to fully utilize the space resources within the mine group, use the internal soil discharge yards of adjacent mines for soil discharge, and use methods such as connecting the soil discharge yards and building intermediate bridges to shorten the transportation distance and reduce the overall soil discharge cost of the open-pit mine group.

[0103] In one implementable method of the embodiment of the present disclosure, it is necessary to study and analyze the annual mining and drainage volume and the mining and drainage space relationship during the diversion period of the open-pit mine based on the scale of raw coal production, combined with the mining status, topographic and geological data, etc., to determine the amount of drainage space shortage in the early stage of the diversion, so as to optimize the mining procedure and determine the boundary of the target open-pit mine. Therefore, in order to optimize the mining procedure, it can also be implemented by but not limited to the following methods: determine the parameter relationship of the target open-pit mine based on the length of the forced pushing working line, the mining and stripping volume and the drainage space; perform data analysis and processing on the parameter relationship to obtain the boundary of the open-pit mine.

[0104] In the disclosed embodiment, there is a close relationship between the length of the forced working line, the mining volume and the dumping space. They influence each other in mine design and jointly determine the production capacity and economic benefits of the mine. Therefore, after determining the parameter relationship of the target open-pit mine, the boundary of the open-pit mine can be directly obtained based on the parameter relationship.

[0105] Among them, the open-pit mine boundary refers to the boundary position of the ore body or ore layer during the mining process of the target open-pit mine, that is, the actual edge of the ore body or the limit of the mining range. The length of the forced push working line refers to the length of the working line for stripping ore or waste rock during the mining of the target open-pit mine. This working line usually refers to the front line along the mining front, that is, the area where stripping operations are being carried out at the edge of the mine pit. The stripping engineering volume refers to the total amount of soil and rock that needs to be stripped during the mining process of the target open-pit mine, including the waste rock covering the ore layer (cover layer) and the waste rock between the ore layers (interlayer). The soil discharge space refers to an area specially set up to store waste rock stripped from the mining process of the target open-pit mine.

[0106] In one implementable method of the embodiment of the present disclosure, it is necessary to study and optimize the layout of the stripping work line in the first mining area, and establish a mine working line calculation model to calculate the mine transportation distance, and obtain an optimized work line layout plan that saves transportation distance and transportation costs, thereby increasing economic benefits. Therefore, in order to increase economic benefits, it can also be implemented by but not limited to the following methods: data abstraction processing is performed on the working face transportation route data to obtain processed transportation route data, and model construction processing is performed based on the processed transportation route data and a preset construction algorithm to obtain a transportation distance model; the amount of flat plate stripping materials and the location of the waste dump contained in the mine data are obtained, and the working face transportation route data, the amount of flat plate stripping materials and the location of the waste dump are input into the transportation distance model for data processing to obtain the working line layout plan.

[0107] In the embodiment of the present disclosure, the preset construction algorithm is a custom-set algorithm, such as a supervised learning algorithm, an unsupervised learning algorithm, etc. Specifically, the embodiment of the present disclosure does not limit the preset construction algorithm.

[0108] Among them, according to the working line layout combined with the triangle characteristics, the working face transportation line is abstracted, and the transportation distance model of the working face moving pit line under different working line layouts is established, and the transportation distance calculation method of different working line layouts is provided, which simplifies the design process. According to the established working face moving pit line transportation distance calculation model, combined with the amount of material stripped from each flat plate, the location of the waste dump, and the transportation route, the comprehensive transportation distance of various layout schemes, the corresponding transportation cost, and the impact on the electric shovel layout are calculated, and the optimal layout scheme is finally determined as the working line layout scheme among all the layout schemes.

[0109] In one implementable method of the disclosed embodiment, in case that the bottom plate inclination of the coal seam in anticline structure in an open-pit mine increases sharply and the soil discharge space is limited, it is necessary to increase the soil discharge capacity through optimized design, that is, to solve the soil discharge problem in the anticline area by designing a new soil discharge plan. Therefore, in order to increase the soil discharge capacity to meet the soil field disposal, it can also be implemented by but not limited to the following methods: determine the soil discharge data of the two sides of the inclined tower based on the support force data; determine the soil discharge plan according to the soil discharge data of the two sides of the inclined tower and the bottom plate blasting position contained in the mine field data.

[0110] In the disclosed embodiment, full use is made of the supporting force of the inclined bottom plate and the end sides, and soil is discharged obliquely with the two sides to form a stable triangular support structure. Combined with the grooves after blasting of the bottom plate, the resulting soil discharge plan can effectively increase the stability of the soil discharge yard, thereby meeting the requirements of soil discharge in the yard and effectively solving the soil discharge problem in the anticline area.

[0111] In one implementable method of the embodiment of the present disclosure, the dumping problem of each open-pit mine is comprehensively considered from the perspective of an open-pit mine group, and the dumping yards of each mine in the mine group are uniformly planned. When an open-pit mine in the mine group has insufficient dumping space due to objective factors such as special geological conditions, consider formulating a dumping yard sharing plan, that is, a dumping yard interconnection plan. Regarding the determination of the dumping yard interconnection plan, it can also be implemented by but not limited to the following methods: determining the distance value between the target dumping yard and each of the other dumping yards based on the dumping yard data; determining the interconnection method between the target dumping yard and each of the other dumping yards through the dumping yard data and the distance value; and interconnecting the target dumping yard with each of the other dumping yards according to the interconnection method to obtain the dumping yard interconnection plan.

[0112] In summary, the embodiments of the present disclosure can achieve the following technical effects:

[0113] 1.
