[0001] The invention belongs to the technical field of ore body mining, and relates to an ore body mining system and a mining method, in particular to a 7-type shield support downward horizontal non-explosive mining system and a mining method. Background Art

[0002] The vast majority of domestic metal and non-metal broken thin ore body mines are mined using methods such as ore retention and wall cutting and filling. The recovery methods adopted are all traditional blasting and ore-dropping technologies, which have great support difficulties and low filling efficiency. In addition, the technology also has problems such as high safety risks, low ore-dropping efficiency, inability to operate continuously, high blasting costs, high depletion loss rates, and inability to achieve mechanization and intelligent requirements. Under the influence of these problems, it has caused many points and wide areas, human sea tactics, low production efficiency of individual ore blocks, high ton of ore costs, and a sharp increase in safety risks, which restrict the sustainable development of mining enterprises. Difficulties and bottlenecks.

[0003] In order to reduce the occurrence of roof falls and slab collapse, the main type of accidents in the safety management of non-coal mines, and at the same time improve the operating efficiency indicators of mining enterprises, it is necessary to provide a mining system and method using special protective supports to solve the problems of high safety risks, frequent process changes, low production efficiency, and low degree of mechanization in the mining process.

[0004] By using a chisel and a "7" type shield support, we jointly designed and invented a downward horizontal non-explosive mining method using a "7" type shield support, which can effectively solve problems such as high safety risks, frequent process changes, low production efficiency, and low degree of mechanization. Summary of the invention

[0005] The purpose of the present invention is to provide a method for horizontal non-explosive mining with a 7-type shield support, so as to solve the technical problems existing in the prior art of non-coal mines in the production process, such as high safety risks, frequent process conversion, low degree of mechanization and low production efficiency.

[0006] To achieve the above purpose, the specific technical solutions of the present invention are as follows:

[0007] A 7-type shield support downward horizontal non-explosive mining system, which includes an outer vein channel, an inner vein channel, a vein-penetrating tunnel and a communication channel, wherein the inner vein channel is distributed in the ore vein and is used for support, support installation, mining and ventilation;

[0008] The extra-vein passage is distributed in the middle of the long-wall ore body outside the ore vein and runs through each section of the long-wall ore body. It is used for equipment entry and exit, parking, personnel entry and exit of the mining area, material transportation and ventilation.

[0009] The communication channels are arranged at intervals in the height direction of the longwall ore body, and the two ends are connected to the inner-vein mining area and the outer-vein channel respectively;

[0010] The vein-penetrating tunnels are respectively arranged at the upper end and the lower end outside the ore vein, located between the outer-vein channel and the inner-vein channel, and connecting the outer-vein channel and the inner-vein channel.

[0011] The outer vein channel includes an outer vein transport lane, an ore chute and an inclined ramp distributed along the length direction of the longwall ore body. The outer vein transport lane is horizontally arranged and includes an upper middle section outer vein transport lane and a lower middle section outer vein transport lane. The upper middle section outer vein transport lane and the lower middle section outer vein transport lane are respectively connected to the inner vein channel of the longwall ore body through the through-vein lane;

[0012] The ore chute passes through each segment of the longwall ore body and forms an obtuse angle with the horizontal plane. Each segment of the ore chute is connected to the ramp respectively.

[0013] The ramp passes through each section of the longwall ore body, and the upper and lower ends of the ramp are respectively connected to the vein tunnel.

[0014] The intra-vein channel includes an upper-middle section along-vein laneway and an upper-vein laneway. The upper-middle section along-vein laneway is horizontally arranged and extends along the strike direction of the longwall ore body, and is connected to the extra-vein channel through a through-vein laneway.

[0015] The vein-going uphill includes the east side vein-going uphill and the west side vein-going uphill which are respectively arranged at both ends of the ore body along the dip direction of the longwall ore body. The vein-going uphill is arranged along the dip extension direction of the longwall ore body, passing through the upper and lower ends of the longwall ore body, and the upper ends are respectively connected with the upper and middle sections of the vein-going tunnels.

[0016] The vein-penetrating tunnel comprises an upper middle section vein-penetrating tunnel located at the upper end outside the ore vein and a lower middle section vein-penetrating tunnel located at the lower end outside the ore vein.

[0017] The communication passage includes a mine communication passage and a chute communication passage. The number of the mine communication passages and the chute communication passages are respectively multiple and evenly distributed along the height direction of the longwall ore body. The two ends of the mine communication passage are respectively connected to the mine and the ramp of the longwall ore body, and the two ends of the chute communication passage are respectively connected to the ramp and the ore chute.

[0018] A mining method of a 7-type shield support downward horizontal non-explosive mining system, comprising the following steps:

[0019] S1, install brackets in the upper middle section of the lane along the vein, and the brackets are arranged in series from the east side along the vein uphill to the west side along the vein uphill through the support beams;

[0020] S2, after installation and layout, start from the middle position along the vein to both ends, use the chisel to perform backward downhill drilling, and mine at an angle of 15° to both sides. After mining to a vertical height drop of 1m, drill horizontally backward for 1m. During this period, the scraper follows to carry out slag in and out, transfer ore to the ramp, and then transfer it to the ore chute through the ore chute connecting road, unload it into the ore chute, until the end of the drilling is only about 4m of the machine body length left, turn the chisel in the mining field connecting road, and drill the remaining 4m at the end. The chiseled part of the ore is unloaded along the vein at both ends of the longwall ore body. During the downward drilling, the support is adjusted and lowered simultaneously;

[0021] S3, when both ends of the longwall ore body are mined and lowered by 1m, step S2 is filled again from the bottom of the 15° slope along the vein, and step S2 is repeated twice on the basis of step S2, and finally the horizontal shield support is lowered by 3m, and the middle part of the support forms a 15° arch;

[0022] S4, transport ore from the upper middle section along the vein roadway to lay waste rock with a height of about 1m on the upper support. After 2-3 times of laying, stop, and form a 2-3m waste rock cover cushion above the support to reduce the impact of rock collapse on the support during subsequent mining, and complete the mining preparation;

[0023] S5, excavate new stope connection road and chute connection road from the ramp. The new stope connection road is parallel to the upper and middle sections of the vein tunnel, and the height difference between adjacent stope connection roads is 4m. The new chute connection road is parallel to the upper and middle sections of the vein tunnel, and the height difference between adjacent chute connection roads is 8m. After the stope connection road exposes the vein of the longwall ore body, the chisel drills the ore body in the 15° arch area backward and downward until the 15° arch area becomes horizontal. During this period, the method of drilling, mining and adjusting the frame is still adopted;

[0024] S6, after the mining of the arched area is completed, the entire horizontal rock is drilled down by 1m along the vein. After descending 1m, the ramp and the mining area connecting road are newly excavated, and the drilling, mining and frame adjustment are continued downward according to steps S2, S3, S5 and S6. After the 3m cycle is completed, step S6 is repeated from the new mining area connecting road of the next section, and the cycle is repeated until the first layer of the vein is reached.

[0025] In the steps S5 and S6, after the connecting road is newly excavated and before continuing to be put into production, the previous connecting road needs to be blocked with a blocking wall to prevent the upper waste rock from being unloaded from there and to increase the stress points of the support at that location.

[0026] Every time a longwall ore body is mined downwards by 8m, it is necessary to penetrate the ore chute to the next layer point by digging a chute connecting road in the ramp.

[0027] All mining and cutting works before the stope is ready for formal mining are carried out by blasting, and steps S1 to S6 along the vein are mined by chiseling machines without blasting;

[0028] The vein-going uphill is arranged in the middle position of the end of the upper middle section of the vein-crossing tunnel. Ventilators are arranged in the east vein-going uphill and the west vein-going uphill, and the ventilation mode in the mining field can be flexibly changed according to the mining direction of the chiseling machine.

[0029] In the steps S5 and S6, the stope connecting roads can be constructed in advance, and each time the connecting roads are arranged, they need to be staggered with the previous two connecting roads and not on the same vertical plane.

[0030] The beneficial effects of the present invention are as follows: the present invention provides a 7-type shield support downward horizontal non-explosive mining system and mining method, and by designing an outer vein channel, an inner vein channel, a through-vein tunnel and a connecting channel, provides a safe mining space for mechanized mining using a chisel, thereby improving the safety level of the mining system. At the same time, by providing a mining method, making full use of the flexibility of the special support and the characteristics of the scraper, mechanical mining is used to replace explosive mining, which greatly reduces the blasting cost and labor cost. At the same time, it also reduces the difficulty of support and the risk factor in the mining process, simplifies the mining process, improves the mechanization level of the mining process and the ore-dropping efficiency, and can achieve continuous operation, thereby effectively improving the production efficiency of the ore block and reducing the ton ore cost.

[0040] Specifically, Figure 1 , Figure 2 As shown, the extra-vein channel includes an extra-vein transport lane, an ore chute 7 and a ramp 6 distributed along the length direction of the longwall ore body. The extra-vein transport lane is horizontally arranged and includes an upper middle section extra-vein transport lane 3 and a lower middle section extra-vein transport lane 5. The upper middle section extra-vein transport lane 3 and the lower middle section extra-vein transport lane 5 are respectively connected with the intra-vein channel of the longwall ore body through the through-vein lane; the ore chute 7 runs through each section of the longwall ore body and forms an obtuse angle with the horizontal plane.

It should be noted that the support used in this embodiment is a special support for metal and non-metal broken thin ore body mines - "7" type shielding support 11, and its specific structure is as follows Figure 5 As shown;

[0046] S2, after the installation and layout is completed, the chisel is used to perform backward downhill drilling from the middle position along the vein to both ends, and mining is carried out on both sides at an angle of 15°. This mining method can ensure that the slope connecting roads can be arranged at intervals, so as to provide space for the scraper to move and discharge slag. When the mining reaches a vertical height of 1m, the horizontal backward drilling is performed for 1m. During this period, the scraper follows to carry out slag in and out operations, transport ore to the ramp 6, and then transport it to the ore chute 7 through the ore chute connecting road 16, and unload it into the ore chute 7. When the drilling reaches the end, only about 4m of the machine body length is left. The chisel is turned around in the mining field connecting road 8, and the remaining 4m of the end is drilled forward. Part of the ore that has been chiseled off is unloaded along the vein at both ends of the longwall ore body. During the downward drilling, the support is adjusted and lowered synchronously;

[0047] S3, when both ends of the longwall ore body are mined and lowered by 1m, step S2 is filled again from the bottom of the 15° slope along the vein, and step S2 is repeated twice on the basis of step S2, and finally the horizontal shield support is lowered by 3m, and the middle part of the support forms a 15° arch;

[0048] S4, transport ore from the upper middle section along the vein roadway 1 to lay waste rock with a height of about 1m on the upper support. After 2-3 times of laying, stop, and a 2-3m waste rock protection cushion layer 12 is formed above the support. In this embodiment, the waste rock is laid 3 times to form a 3m waste rock protection cushion layer 12 above the support to reduce the impact of rock collapse on the support during subsequent mining, and complete the mining preparation;

[0049] S5, normal mining stage 14: excavate new mine contact roads 8 and mine chute contact roads 16 from the ramp 6, the new mine contact roads 8 are parallel to the upper and middle section vein tunnels 2, and the height difference between adjacent mine contact roads 8 is 4m, the new mine chute contact roads 16 are parallel to the upper and middle section vein tunnels 2, and the height difference between adjacent mine chute contact roads 16 is 8m, that is, every time the longwall ore body is mined 8m downward, it is necessary to dig the mine chute contact road 16 in the ramp 6 to connect the ore chute 7 to the next layer point. It should be noted that the mine contact road 8 can be constructed in advance, and each time the mine contact road 8 and the mine chute contact road 16 are arranged, they need to be staggered with their own contact roads in the previous two times and not on the same vertical plane to ensure the stability and safety of the entire system. After the stope contact road 8 exposes the vein of the longwall ore body, the chisel drills the ore body in the 15° arch area backward and downward until the 15° arch area becomes horizontal. During this period, the drilling, ore removal and frame adjustment are still adopted;

[0050] S6, after the arch area is mined, the entire horizontal vein is drilled down by 1m, and after descending 1m, the ramp 6 and the stope connection road 8 are newly excavated, and the steps S2, S3, S5, and S6 are continued to be cyclically drilled, mined, and adjusted until the 3m cycle is completed, and then step S6 is repeated from the next segment of the new stope connection road 8, and the cycle is repeated until it reaches Figure 1 The first layer along the vein is located below the bottom of the ore body to be mined and adjacent to the bottom of the ore body to be mined.

[0051] Furthermore, in the steps S5 and S6, after the new excavation of the connecting road is completed and before continuing the production, the previous connecting road needs to be blocked with a blocking wall to prevent the upper waste rock from being unloaded from there and to increase the stress points of the support at that location.

[0052] It should be noted that the mining and cutting works before the stope mining preparation stage 13 are all carried out by blasting, and the steps S1 to S6 along the vein recovery are all carried out by non-explosive rock drilling with a chisel;
