Description

TECHNICAL FIELD

[0002] In the process of developing coal resources, it is inevitable to form a state of close-range multi-working face mining.

Therefore, how to determine the coordinated mining mode of the working face group through an accurate and reliable method to ensure the stability of the mine and the safety production of the mine has become a problem to be solved.

[0038] The exemplary embodiments of the present application are described below with reference to the accompanying drawings, including various details of the embodiments of the present application to assist in the understanding thereof, which should be considered as merely exemplary. Thus, those of ordinary skill in the art will recognize various changes and modifications of the embodiments described herein, which do not depart from the scope and spirit of the present application. Also, for the sake of brevity and clarity, descriptions of well-known functions and constructions are omitted from the following description.

[0039] The mining area working face coordinated mining method, device and electronic device of the present application are described in detail below using embodiments.

[0040] Figure 1 A flowchart of a mining area working face coordinated mining method provided for an embodiment of the present application.

[0041] As shown in Figure 1 The mining area working face coordinated mining method proposed in the present embodiment is executed by a communication initiator and includes the following steps:

[0042] S101, obtaining a group of adjacent working faces to be mined, wherein the group of adjacent working faces to be mined includes a working face to be mined and a consecutive working face corresponding to the working face to be mined.

[0043] The adjacent working face group to be mined consists of the working face to be mined, the corresponding successor working face, and the coal pillar in between.

[0044] It should be noted that before obtaining the adjacent working face group to be mined, the coordinated mining area can be determined in advance, and the working faces to be mined within the coordinated mining area can be obtained. According to the requirements of the coal mine safety regulations, a maximum of one coal mining working face can be arranged on one wing of the working face to be mined, thereby determining the successor working face corresponding to the working face to be mined.

[0045] For example, such as Figure 2 As shown, since there is no exploitable area on the west wing of the 23rd mining area of ​​Yuejin Coal Mine (the west wing of the 23rd mining area is not shown in the figure), the possible successor working faces on the east wing of the 23rd mining area of ​​Yuejin Coal Mine are working face 23092, working face 23150, or working face 23170. The possible successor working faces on the west wing of the 21st mining area of ​​Changcun Coal Mine are working face 21162 or working face 21240. The possible successor working face on the east wing of the 21st mining area of ​​Changcun Coal Mine is working face 21170. Therefore, the adjacent working face groups to be mined are 23092-21162, 23092-21240, 23150-21162, 23150-21240, 23170-21162, 23170-21240, 21162-21170, and 21240-21170.

[0046] S102. Determine the coordination value of each working face in the adjacent working face group to be mined based on the characteristic parameters and preset rules.

[0047] In this embodiment of the application, the characteristic parameters of the adjacent working face group to be mined include the average thickness of the coal seam, the average dip length, the width of the intermediate coal pillar, the vertical offset, and the distance between the cut-off holes.

[0048] For example, such as Figure 3 As shown, for an adjacent working face group consisting of two working faces, A and B, the average coal seam thickness is the average coal seam thickness obtained from all known geological boreholes within the two working faces; the average dip length is the average dip length of the two working faces; the width of the intermediate coal pillar is the width of the coal pillar between the two working faces. If the intermediate coal pillar is not rectangular but an irregular strip, then the width of the intermediate coal pillar is the average of the maximum and minimum widths between the two working faces; the vertical offset is the vertical distance between the roadways of the two working faces. If the roadways of two adjacent working faces are not completely parallel, then the vertical offset is the average of the maximum and minimum offsets; the cut-off distance is the distance between the middle of the cut-off points of the two working faces.

[0049] Optionally, after the characteristic parameters of the adjacent working face group to be mined are acquired, a preset coordination value corresponding to the characteristic parameters can be acquired, and the coordination value of each working face in the adjacent working face group to be mined is calculated according to the preset coordination value and the preset coordination value, so as to determine the coordination value of each working face.

[0050] S103, determining a target connecting working face corresponding to the working face to be mined according to the coordination value.

[0051] It should be noted that when the mining area (well) coordinated mining design under different geological conditions is designed, the following aspects are included, for example: 1, the working face inside the fold is recovered from syncline to anticline; 2, the recovery speed is controlled to be less than the safety speed of the working face with dynamic appearance; 3, the mining height of the working face near the graben should be less than 6m, and the protection coal pillar width should be greater than 50m; 4, the large roadway is changed from coal seam arrangement to rock layer arrangement, the crossheading and the large roadway are changed from a certain angle to perpendicular arrangement, the two wings of the panel are changed from mining to one wing mining, the working faces of each panel are alternately mined, and the working faces in the same mining area are sequentially mined; 5, under the conditions of thick conglomerate, fault and fold, the upper and lower protective layers of the coal seam are mined; 6, the working face under the thick and hard rock layer is arranged with a negative coal pillar roadway, however, the above-mentioned method for preventing rock burst in coordinated mining pays more attention to the influence of reasonable arrangement of a single working face on rock burst prevention, and does not involve the prevention of rock burst from the perspective of coordinated control between multiple working faces.

[0052] The mining area working face coordinated mining method provided in the application can determine the target connecting working face through the coordination value of each working face, and determine the coordinated mining method through the working face to be mined and the connecting working face, so that the mining disturbance between the working faces to be mined can be more effectively avoided, and the stability and safety production of the mine can be ensured.

[0053] Optionally, after the coordination value is acquired, the coordination value of each connecting working face corresponding to the working face to be mined is acquired from the coordination value, the coordination value of each connecting working face is sorted from large to small, and the connecting working face corresponding to the coordination value located at the first position in the sorting result is determined as the target connecting working face corresponding to the working face to be mined.

[0054] For example, for the 23092-21162 adjacent working face group to be mined and the 23092-21240 adjacent working face group to be mined, the connecting working face selected for the 23092 working face to be mined is the 21162 working face and the 21240 working face, and when the coordination value of the 21240 working face is greater, the 21240 working face is selected as the target connecting working face of the 23092 working face.

[0055] The application provides a mining face coordinated mining method, comprising the following steps: acquiring a to-be-mined adjacent working face group, wherein the to-be-mined adjacent working face group comprises a to-be-mined working face and a corresponding successive working face of the to-be-mined working face; determining a coordination value of each working face in the to-be-mined adjacent working face group according to a characteristic parameter of the to-be-mined adjacent working face group and a preset rule; and determining a target successive working face corresponding to the to-be-mined working face according to the coordination value. The target successive working face is determined by the coordination value of each working face, and the coordinated mining mode is determined by the to-be-mined working face and the successive working face, so that the mining disturbance between the to-be-mined working faces is avoided, and the stability and safe production of the mine are ensured.

[0056] It should be noted that in the embodiment of the application, when attempting to determine the coordination value of each working face in the to-be-mined adjacent working face group, a preset coordination value corresponding to the characteristic parameter can be acquired, and the coordination value of each working face in the to-be-mined adjacent working face group is calculated according to the preset rule and the preset coordination value to determine the coordination value of each working face.

[0057] As a possible implementation manner, as shown in Figure 4 the above embodiment, the specific process of determining the coordination value of each working face in the to-be-mined adjacent working face group according to the characteristic parameter of the to-be-mined adjacent working face group and the preset rule in the step S102 comprises the following steps:

[0058] S401, acquiring a preset coordination value corresponding to the characteristic parameter.

[0059] It should be noted that the setting of the preset coordination value in the application is not limited, and can be set according to the actual situation.

[0060] For example, as shown in Table 1, the to-be-mined adjacent working face group with the smallest average thickness of coal seam, the shortest average length of inclination, the largest width of intermediate coal pillar, the largest vertical offset, and the largest open-off cut distance can be selected according to the characteristic parameter of the to-be-mined adjacent working face group. The preset coordination value of the smallest average thickness of coal seam is set to 0.25, the preset coordination value of the remaining average thickness of coal seam is 0, the preset coordination value of the shortest average length of inclination is set to 0.26, the preset coordination value of the remaining average length of inclination is 0, the preset coordination value of the largest width of intermediate coal pillar is set to 0.20, the preset coordination value of the remaining width of intermediate coal pillar is 0, the preset coordination value of the largest vertical offset is set to 0.14, the preset coordination value of the remaining vertical offset is 0, the preset coordination value of the largest open-off cut distance is set to 0.15, and the preset coordination value of the remaining open-off cut distance is 0.

[0061] Table 1

[0062]

[0063] S402, calculate the coordination value of each working face in the group of adjacent working faces to be mined according to the preset rule and the preset coordination value.

[0064] In the embodiment of the present application, after the preset coordination value is obtained, the coordination value of each working face in the group of adjacent working faces to be mined can be calculated according to the preset rule and the preset coordination value, so as to determine the coordination value of each working face.

[0065] For example, as shown in Table 2, the coordination value of the group of adjacent working faces to be mined 23092-21162 is 0.25, the coordination value of the group of adjacent working faces to be mined 23092-21240, 23150-21240 and 23170-21240 is 0, the coordination value of the group of adjacent working faces to be mined 23150-21162 is 0.26, the coordination value of the group of adjacent working faces to be mined 23170-21162 is 0.49, i.e. 0.20+0.14+0.15=0.49, the coordination value of the group of adjacent working faces to be mined 21162-21170 is 0.66, i.e. 0.25+0.26+0.15=0.66, and the coordination value of the group of adjacent working faces to be mined 21240-21170 is 0.34, i.e. 0.20+0.14=0.34.

[0066] Table 2

[0067]

[0068] S403, determine the coordination value of each working face in the group of adjacent working faces to be mined according to the coordination value of the group of adjacent working faces to be mined.

[0069] It should be noted that after the coordination value of the group of adjacent working faces to be mined is obtained, the coordination values of the working faces to be mined appearing in all the groups of adjacent working faces to be mined can be added to determine the coordination value of each working face in the group of adjacent working faces to be mined.

[0070] For example, as shown in Table 3, the coordination value of the working face to be mined 23092 is 0.25, the coordination value of the group of working faces to be mined 23150 is 0.26, the coordination value of the working face to be mined 23170 is 0.49, the coordination value of the working face to be mined 21162 is 1.66, i.e. 0.25+0.66+0.26+0.49=1.66, the coordination value of the working face to be mined 21240 is 0.34, and the coordination value of the working face to be mined 21170 is 1, i.e. 0.66+0.34=1.

[0071] Table 3

[0072]

[0073] The application provides a mining face coordinated mining method, by obtaining a preset coordination value corresponding to a characteristic parameter, calculating a coordination value of a group of adjacent working faces to be mined according to a preset rule and the preset coordination value; and determining the coordination value of each working face in the group of adjacent working faces to be mined according to the coordination value of the group of adjacent working faces to be mined, so that the application can more accurately determine a target connecting working face by determining the coordination value of each working face in the group of adjacent working faces to be mined through the characteristic parameter, which lays a foundation for subsequent determination of a coordinated mining mode.

[0074] It should be noted that in the embodiment of the application, when trying to determine a target connecting working face corresponding to a working face to be mined, the coordination value of each connecting working face corresponding to the working face to be mined can be obtained from the coordination value. The coordination values of each connecting working face are sorted in descending order, and the connecting working face corresponding to the coordination value located at the first position in the sorting result is determined as the target connecting working face corresponding to the working face to be mined.

[0075] As a possible implementation manner, as shown in Figure 5 On the basis of the above embodiment, the specific process of determining the target connecting working face corresponding to the working face to be mined according to the coordination value in step S103 includes the following steps:

[0076] S501, the coordination values of each connecting working face are sorted in descending order.

[0077] For example, the optional connecting working face of the working face to be mined in the east wing of the 23 mining area of the Yuejin Coal Mine is the 23092 working face, the 23150 working face or the 23170 working face, and the coordination values are sorted in descending order as follows: the connecting working face 23170 (coordination value 0.49), the connecting working face 23150 (coordination value 0.26), and the connecting working face 23092 (coordination value 0.25); the optional connecting working face of the working face to be mined in the west wing of the 21 mining area of the Changcun Coal Mine is the 21162 working face or the 21240 working face, and the coordination values are sorted in descending order as follows: the connecting working face 21162 (coordination value 1.66), and the connecting working face 21240 (coordination value 0.34).

[0078] S502, the connecting working face corresponding to the coordination value located at the first position in the sorting result is determined as the target connecting working face corresponding to the working face to be mined.

[0079] It should be noted that according to the principle that one mining area in a coal mine has at most one coal mining working face in one wing of the same coal seam, the working face with the highest coordination value is selected as the target connecting working face of each wing of each mining area in the coordinated mining area.

[0080] For example, as shown in Figure 2As shown, the target connecting working face of the working face to be mined in the east wing of the 23 mining area of the Yuejin Coal Mine is the 23170 working face, the target connecting working face of the working face to be mined in the west wing of the 21 mining area of the Changcun Coal Mine is the 21162 working face, and the target connecting working face of the working face to be mined in the east wing of the 21 mining area of the Changcun Coal Mine is the 21170 working face.

[0081] It should be noted that in the embodiments of the present application, after the target connecting working face is determined, the coordinated mining mode can be determined based on the target connecting working face, and the evaluation result of the coordinated mining mode is determined.

[0082] As a possible implementation manner, as shown in Figure 6 Based on the above embodiments, the specific process of determining the evaluation result of the coordinated mining mode includes the following steps:

[0083] S601, obtaining the first coordination value mean of the working face to be mined and the target connecting working face corresponding to the working face to be mined, the first number of associated microseismic event groups, and the first microseismic energy.

[0084] It should be noted that for the selected 23170-21162 working face group and 21162-21170 working face group, the first coordination value mean of the 23170-21162 working face group is 1.075, i.e. (0.49+1.66) / 2=1.075, and the first coordination value mean of the 23170-21162 working face group is 1.33, i.e. (1.66+1) / 2=1.33.

[0085] It should be noted that the microseismic events of the working face group can be screened, and the microseismic events with a time interval of 2s-2min between the two working faces are selected, which are called associated microseismic event groups. The first number of associated microseismic event groups and the first microseismic energy can be determined based on the mine microseismic monitoring system.

[0086] S602, obtaining the second coordination value mean of the adjacent working face group that has been mined, the second number of associated microseismic event groups, and the second microseismic energy.

[0087] It should be noted that outside the coordinated mining range of the same mining area, adjacent working face groups that have been mined (for example, the 13230 working face and the 21121 working face at the boundary of the Gengcun Coal Mine and the Qianqiu Coal Mine) are selected, the second coordination value mean of the adjacent working face groups that have been mined is determined, and the second number of associated microseismic event groups and the second microseismic energy are determined based on the mine microseismic monitoring system.

[0088] S603, sort the first coordination value mean and the second coordination value mean in descending order to obtain a first sorting result of the working face group, sort the first number of associated microseismic event groups and the second number of associated microseismic event groups in descending order to obtain a second sorting result of the working face group, and sort the first microseismic energy and the second microseismic energy in descending order to obtain a third sorting result of the working face group.
