[0026] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings.

The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0027] It should be noted that all actions of acquiring signals, information or data in the present disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the device is located and with the authorization given by the owner of the corresponding device.

[0028] Figure 1 It is a flow chart of a method for monitoring mine pressure in a continuous mining and continuous filling working face according to an exemplary embodiment, wherein it should be noted that the method for monitoring mine pressure in a continuous mining and continuous filling working face in this embodiment is executed by a mine pressure monitoring device for a continuous mining and continuous filling working face, and the mine pressure monitoring device for a continuous mining and continuous filling working face can be implemented by software and / or hardware, and the mine pressure monitoring device for a continuous mining and continuous filling working face can be configured in an electronic device. The following description will be given by taking the execution subject as an electronic device as an example.

[0029] like Figure 1 As shown, the method for monitoring the mine pressure in the continuous mining and filling working face includes the following steps:

[0030] Before introducing the method for monitoring the mine pressure in a continuous mining and continuous filling working face according to the embodiment of the present disclosure, it is necessary to explain the structural framework of the method for monitoring the mine pressure in a continuous mining and continuous filling working face according to the present disclosure. Figure 2 As shown, Figure 2 It is a structural framework diagram of the mine pressure monitoring method for the continuous mining and continuous filling working face of the embodiment of the present invention, wherein the monitoring scope includes: mining branch tunnel numbering, monitoring line setting, monitoring branch tunnel setting, and monitoring station setting; the monitoring classification includes: mining branch tunnel wheel grouping, first-level and second-level monitoring lines, first-level and second-level monitoring branch tunnels, and first-level, second-level and third-level monitoring stations; the monitoring indicators include: coal body stress, filling body stress, roof subsidence, roof and floor plate movement and anchor (cable) force; the monitoring instruments include: filling borehole stress gauge, filling delamination meter, filling roof and floor plate movement meter, filling stress gauge and filling anchor (cable) dynamometer.

[0031] In step S101, the mining branch tunnels of the working face are numbered according to odd and even numbers, and are divided into branch tunnel groups according to the mining rounds to which they belong.

[0032] In this embodiment, the working face is divided into two mining stages along the strike direction. The mining sequence of the mining stages is: the first mining stage → the second mining stage.

[0033] Each stage adopts three-step mining, and the number of mining and filling rounds is 3. Each mining stage includes three rounds of branch tunnel groups, and the mining order is: the first round of branch tunnel group → the second round of branch tunnel group → the third round of branch tunnel group.

[0034] Each round of branch roadway group consists of a certain number of branch roadways. The mining time for a single branch roadway is approximately 1.5 days. The number of branch roadways in a single round of the branch roadway group is 20. The mining and filling operations in the working face are carried out in parallel. The time required to complete the mining and filling operations of a single round of the branch roadway group is approximately 30 days, which can ensure the strength stability time of 28 days for the filling body in each branch roadway. After 28 days of mining the first branch roadway in the first round of the branch roadway group, the mining and filling of the first branch roadway in the adjacent second round of the branch roadway group can be carried out. Thus, in the case of 3 mining and filling rounds, the number of mining branch roadways is 60, and with an additional 2 reserved coal pillar branch roadways, the total number of branch roadways in the mining stage is 62.

[0035] Figure 3 As shown in the schematic diagram of the mining sequence, for the mining sequence of the branch roadways in the 1st - 3rd rounds of the 1st mining stage: In the 1st round: Branch roadways 3#, 4#, 9#, 10#, 15#, 16#, 21#, 22#, 27#, 28#, 33#, 34#, 39#, 40#, 45#, 46#, 51#, 52#, 57#, 58#. In the 2nd round: Branch roadways 5#, 6#, 11#, 12#, 17#, 18#, 23#, 24#, 29#, 30#, 35#, 36#, 41#, 42#, 47#, 48#, 53#, 54#, 59#, 60#. In the 3rd round: Branch roadways 7#, 8#, 13#, 14#, 19, 20#, 25#, 26#, 31#, 32#, 37#, 38#, 43#, 44#, 49#, 50#, 55#, 56#, 61#, 62#.

[0036] For the mining sequence of the branch roadways in the 1st - 3rd rounds of the 2nd mining stage: In the 1st round: Branch roadways 63#, 64#, 69#, 70#, 75#, 76#. In the 2nd round: Branch roadways 65#, 66#, 71#, 72#, 77#, 78#. In the 3rd round: Branch roadways 67#, 68#, 73#, 74#, 79, 80#.

[0037] In step S102, according to the relationship between the size of the working face and the mine pressure intensity, monitoring lines are set at predetermined positions and numbered in sequence according to grades, where the monitoring lines include: strike monitoring lines and dip monitoring lines.

[0038] In the embodiment of the present disclosure, according to the mine pressure intensity in different spatio - temporal regions of the working face and the requirements of the monitoring area, the strike monitoring lines and dip monitoring lines of the working face are determined. Among them, the monitoring lines are divided into first - level and second - level, which respectively realize the monitoring of the strongest mine pressure in a larger area and the process mine pressure in a smaller area during the mining of the working face. The monitoring is targeted and the spatio - temporal layout is relatively reasonable.

[0039] As Figure 4 shown, Figure 4It is a schematic diagram of the distribution of monitoring lines. For the primary strike monitoring lines, one primary monitoring line parallel to the working face strike is set at the geometric center of the left and right wings of the working face, at the 1 / 2 position, and a total of 2 primary monitoring lines (YX1# and YX2#) are set. These 2 monitoring lines are at the dip center of the gateway entries of the continuous mining and backfilling working faces on the left and right wings. Generally, the intensity of abutment pressure manifestation is the greatest here, and the monitoring can best reflect the abutment pressure manifestation of the gateway entries of the continuous mining and backfilling working face.

[0040] The primary dip monitoring lines. One primary monitoring line parallel to the working face dip is set at 1 times and 2 times the width of the cut-through of the continuous mining and backfilling working face respectively (YX3# and YX4#). At these positions, the working face is at the first and second square-out positions. Generally, the intensity of abutment pressure manifestation is the most intense here. Monitoring the abutment pressure here is of great significance for mastering the state of the surrounding rock and filling body of the continuous mining and backfilling working face, evaluating the filling effect, and guiding the design of filling mining parameters, etc.

[0041] The secondary strike monitoring lines. One secondary monitoring line parallel to the working face strike is set at the 1 / 5 - 1 / 4 and 3 / 4 - 4 / 5 lengths of the left wing working face dip and at the 1 / 5 - 1 / 4 and 3 / 4 - 4 / 5 lengths of the right wing working face dip respectively, and a total of 4 secondary monitoring lines (EX1#, EX2#, EX3#, EX4#) are set.

[0042] The secondary dip monitoring lines. One secondary monitoring line parallel to the working face dip is set at 0.5, 1.5, and 2.5 times the width of the cut-through of the working face, at the half position of the square-out of the working face, and a total of 3 secondary monitoring lines (EX5#, EX6#, EX7#) are set.

[0043] In step S103, at the intersections of the strike primary monitoring lines with the dip primary monitoring lines and the secondary monitoring lines respectively, select the gateway entries belonging to the first round of gateway entry groups, set the primary monitoring gateway entries and the secondary monitoring gateway entries respectively, and number the monitoring gateway entries according to the grade and order.

[0044] In the embodiment of the present disclosure, the monitoring gateway entries are set in the gateway entries of the first round of groups, which can realize the monitoring of the state of the filling body and the surrounding rock during the whole mining and filling process of the working face. It has the advantage of long monitoring time and can reflect the changes in the state of the filling body and the surrounding rock during the three-round mining and filling process.

[0045] Among them, the primary monitoring gateway entries include: at the intersections of the first primary monitoring line and the second primary monitoring line with the third primary monitoring line and the fourth primary monitoring line respectively, set the first primary monitoring gateway entry, the second primary monitoring gateway entry, the third primary monitoring gateway entry, and the fourth primary monitoring gateway entry.

[0046] As Figure 5 shown, Figure 5It is a schematic diagram of the distribution of branch roadways for monitoring. At the intersections of the first-level monitoring line (YX1#) and the second-level monitoring line (YX2#) with the third-level monitoring line (YX3#) and the fourth-level monitoring line (YX4#) respectively, in the first-round group of branch roadways, first-level monitoring branch roadways are set up. Figure 5 They are represented as YH1#, YH2#, YH3# and YH4# in the figure.

[0047] At the intersections of the first-level strike monitoring line and the second-level dip monitoring line, in the first-round group of branch roadways, second-level monitoring branch roadways are set up. Figure 5 They are represented as EH1#, EH2#, EH3# and EH4# in the figure.

[0048] In step S104, monitoring stations are set up at the intersections of the monitoring branch roadways with the first-level and second-level monitoring lines in the strike direction to monitor the strata pressure indexes of the working face respectively.

[0049] Among them, at the intersections of the first-level monitoring branch roadways with the first-level and second-level monitoring lines in the strike direction, first-level and second-level monitoring stations are set up respectively; at the intersections of the second-level monitoring branch roadways with the first-level and second-level monitoring lines in the strike direction, second-level and third-level monitoring stations are set up respectively.

[0050] One first-level monitoring station and two second-level monitoring stations are set up in the first-level monitoring branch roadways; one second-level monitoring station and two third-level monitoring stations are set up in the second-level monitoring branch roadways.

[0051] Optionally, determine the number and numbers of the monitoring stations in all the monitoring branch roadways: there are 3 intersections of each monitoring branch roadway with the dip monitoring line, so 3 monitoring stations are set up in each monitoring branch roadway. One first-level monitoring station and two second-level monitoring stations are arranged in each first-level monitoring branch roadway; one second-level monitoring station and two third-level monitoring stations are arranged in each second-level monitoring branch roadway.

[0052] Among them, the first-level monitoring station is located at the middle 1 / 2 of the branch roadway, and the two second-level monitoring stations are located at the positions 1 / 5 - 1 / 4 away from the roadway entrance on both sides of the branch roadway (1 / 4 for a single-wing working face and 1 / 5 for a double-wing working face).

[0053] As Figure 6 shown, Figure 6 It is a schematic diagram of the distribution of the monitoring stations. According to this embodiment, the number and numbers of the monitoring stations in all the monitoring branch roadways are as follows:

[0054] At the intersections of the first-level monitoring branch roadways (YH1#, YH2#, YH3#, YH4#) with the first-level monitoring lines (YX1, YX2), that is, at the middle 1 / 2 of the centers of the first-level monitoring branch roadways, one first-level monitoring station (YZ1, YZ2, YZ3, YZ4) is set up at each.

[0055] At the intersections of the primary monitoring crossheadings (YH1#, YH2#, YH3#, YH4#) and the strike secondary monitoring lines (EX1, EX2, EX3, EX4), namely at the 1 / 5 and 4 / 5 positions of the primary monitoring crossheadings from the roadway entrance, 2 secondary monitoring stations (EZ3, EZ4; EZ5, EZ6; EZ9, EZ10; EZ11, EZ12) are respectively set up.

[0056] At the intersections of the secondary monitoring crossheadings (EH1#, EH2#, EH3#, EH4#) and the strike secondary monitoring lines (EX1, EX2, EX3, EX4), namely at the 1 / 2 position of the centers of the secondary monitoring crossheadings, 1 secondary monitoring station (EZ1, EZ2, EZ7, EZ8) is set up at each intersection.

[0057] At the intersections of the secondary monitoring crossheadings (EH1#, EH2#, EH3#, EH4#) and the strike secondary monitoring lines (EX1, EX2, EX3, EX4), namely at the 1 / 5 and 4 / 5 positions of the secondary monitoring crossheadings from the roadway entrance, 2 tertiary monitoring stations (SZ1, SZ2; SZ3, SZ4; SZ5, SZ6; SZ7, SZ8) are respectively set up.

[0058] Among them, the strata pressure indexes include: the first index, the second index and the third index; among them, the first index includes: monitoring of coal body stress, filling body stress, roof subsidence, roof-to-floor convergence and the stress of bolts (cables); the second index includes: roof-to-floor convergence, filling body stress; the third index includes: filling body stress.

[0059] The strata pressure indexes are all monitored by dedicated filling strata pressure monitoring instruments, and the filling strata pressure monitoring instruments include: filling borehole stress gauges, filling separation meters, filling roof-to-floor convergence meters, filling stress gauges and filling bolt (cable) force gauges.

[0060] Optionally, the coal pillar stress is obtained by a filling borehole stress gauge; the roof separation amount is obtained by a filling roof separation meter; the roof-to-floor convergence is obtained by a filling roof-to-floor convergence meter; the filling body stress is obtained by a filling stress gauge; the stress of bolts (cables) is obtained by a filling bolt (cable) force gauge.

[0061] As a possible implementation method, at the intersections of the primary monitoring crossheadings and the primary monitoring lines and secondary monitoring lines in the strike direction, primary monitoring stations and secondary monitoring stations are respectively set up; at the intersections of the secondary monitoring crossheadings and the primary monitoring lines and secondary monitoring lines in the strike direction, secondary monitoring stations and tertiary monitoring stations are respectively set up.

[0062] In summary, by numbering the mining headings of the working face as odd or even numbers and dividing the headings into heading groups according to the filling and mining rounds to which they belong; setting monitoring lines at predetermined positions according to the relationship between the size of the working face and the mine pressure intensity, and numbering the monitoring lines in order of grade, where the monitoring lines include: strike monitoring lines and dip monitoring lines; at the intersections of the first-level strike monitoring lines with the first-level dip monitoring lines and the second-level dip monitoring lines respectively, selecting the headings belonging to the first-round heading group, and respectively setting first-level monitoring headings and second-level monitoring headings, and numbering the monitoring headings respectively in order of grade; setting monitoring stations at the intersections of the monitoring headings with the first-level monitoring lines and the second-level monitoring lines in the strike direction to respectively monitor the mine pressure indexes of the working face.

The filling roof separation indicator 2 is installed in the middle of the roof of the branch roadway, and the depths of the shallow base point and the deep base point are determined in combination with the roof conditions. In addition, the filling roof separation indicator 2 can also be used to monitor the displacement amount of both sides of the branch roadway.
