Description

Technical Field

[0001] The invention belongs to the technical field of non-explosion continuous mining in non-coal mines, and in particular relates to a mechanical rock breaking continuous mining method suitable for gently inclined layered ore beds. Background Art

[0002] Gently inclined layered deposits in non-coal mines are one of the types of difficult-to-mine deposits. At present, there are two main ways to mine this type of deposit: blasting and mechanical rock breaking. Among them, the mining site of blasting mining has a high ore depletion rate, a large disturbance intensity to the roof surrounding rock, and poor connection between processes, which restricts the development of mines in the direction of continuity, mechanization and less manpower; while mechanical rock breaking mainly uses cantilever tunneling machines or cutting machines and other equipment to break rocks by cutting, rolling, and impact cutting, but when facing hard rocks, there are problems such as "unable to break and slow to mine". For this reason, in recent years, the industry has proposed a microwave-assisted mechanical rock breaking method, that is, microwaves are used to irradiate the hard rock on the face before mechanical rock breaking to produce high-temperature fragmentation and rupture, thereby improving the cuttability of hard rock. This method not only avoids the intermittent and high-risk nature of traditional rock drilling and blasting, but also improves the efficiency of traditional single mechanical excavation of hard rock.

[0003] However, this method still has the problem of difficulty in synchronizing microwave irradiation and mechanical cutting on the same working surface, resulting in discontinuous ore supply in the mining area and large power consumption losses in transportation. At the same time, the high temperature generated by microwaves puts higher requirements on the ventilation of the working surface. Summary of the invention

[0004] In order to solve the problem of microwave irradiation and mechanical cutting being difficult to synchronize and improve the continuity of the process in the stope, a mechanical rock breaking continuous mining method suitable for gently inclined layered deposits is proposed to achieve continuous and stable ore output in the stope, and the "mining-loading-transportation" processes do not interfere with each other and the production effect of smooth connection is achieved. At the same time, the corresponding stope ventilation method is proposed to provide a good and safe working environment for the workers and mechanical equipment in the stope.

[0005] In order to achieve the above object, the present invention provides the following technical solutions:

[0006] A mechanical rock breaking continuous mining method suitable for gently inclined layered ore deposits comprises the following steps:

[0007] Step 1: Arrangement of stope structure: according to the occurrence characteristics of the ore deposit, the middle section is divided along the ore body trend, and the middle section is divided into pan areas along the ore body trend. The pan areas are further divided into ore blocks. If the ore body thickness exceeds the maximum mining height of the mining equipment, the ore blocks are divided into layers;

[0008] Step 2, planning the mining and cutting project; the mining and cutting project includes the middle section connecting tunnel, the panel area belt transport tunnel, the panel area auxiliary transport tunnel, the middle section return air tunnel, the rock drilling transport tunnel and the panel area chute;

[0009] Step 3, formulating a mining sequence; the mining sequence mainly includes a mining sequence between middle layers and a mining sequence between ore blocks in a panel area;

[0010] Step 4, ore block recovery; the ore block recovery includes microwave irradiation, mechanical cutting and rock breaking, and ore dropping;

[0011] Step 5, ore transportation; the ore transportation includes transportation within the stope, ore transportation in the panel area and ore transportation in the middle section, wherein the ore cut in the stope is transferred to the transfer machine behind the equipment by the loading mechanism of the tunneling machine, and then transported out of the stope by the scraper conveyor arranged in the rock drilling transportation tunnel; the ore in the panel area is transferred by the scraper conveyor to the belt conveyor in the panel area, and then transported by the belt conveyor to the belt conveyor in the middle section connecting tunnel, realizing continuous and stable transportation of the whole process of stope-panel-middle section;

[0012] Step 6, ventilation of the mining area; the mining area ventilation is specifically that the rock drilling and transportation lane is used as the ventilation air inlet lane of the entire mining area; the fresh air flow path is the panel area connection lane → the panel area main transportation lane → the rock drilling and transportation lane → the mining face; the dirty air flow path is the mining face → the middle section return air lane, and ventilation is used to ensure that the temperature of the mining working face is below 26°;

[0013] Step 7, filling; the filling is specifically as follows: after all mining in the stope is completed, a full tailings cemented filling body is used for filling, and the filling height is the layer height, generally 4 to 6 meters, wherein the lower 4 meters adopt a low-strength filling ratio, and the upper 1 to 2 meters adopt a high-strength filling ratio;

[0014] Step 8, pillar recovery; the pillar recovery means that after all the ore bodies on both sides of the main transport lanes in the disk area arranged in the middle top and bottom pillars are mined and filled, the transport lanes in the pillars will be used as cutting lanes for retreat mining.

[0015] Preferably, the step 1 further comprises the following steps:

[0016] Step 11, the oblique length of the middle section is 80 to 120 m, and top and bottom columns with a width of 15 to 20 m are left between the middle sections;

[0017] Step 12, determining the length of the plate area according to the reasonable transportation distance of the plate area continuous conveying equipment, the plate area length is 400-600m, and a 15m inter-plate pillar is reserved between the plates;

[0018] Step 13: Pseudo-inclined blocks are arranged at a certain angle along the direction of the ore body in the panel area to ensure that the pseudo-inclined angle does not exceed the climbing capacity of the mining equipment. The width of the block is determined according to the stability of the surrounding rock, generally 15 to 20 meters. The height of the block is the thickness of the ore body. When the thickness of the ore body is greater than the maximum mining height of the mining equipment, it is divided into layers, and the layer height is generally 4 to 6 meters.

[0019] Preferably, the step 2 further comprises the following steps:

[0020] Step 21, the middle section connecting tunnel is divided into two types: the inner-vein middle section connecting tunnel and the outer-vein middle section connecting tunnel. The outer-vein middle section connecting tunnel is arranged at the two wings of the ore body as a channel for the transfer of mechanical equipment between adjacent middle sections; the inner-vein middle section connecting tunnel is arranged in the top and bottom pillars of the middle section, and serves as a transportation tunnel for personnel, materials, and ore between the middle sections and a ventilation tunnel;

[0021] Step 22, the panel area belt conveyor lane and panel area auxiliary conveyor lane are arranged in the middle section top and bottom pillars along the ore body direction, the two are 8 to 10 meters apart, and the adjacent middle sections of the panel area share a set of panel area belt conveyor lanes and panel area auxiliary conveyor lanes;

[0022] Step 23, the middle return airway is arranged in the top and bottom columns on the other side of the panel along the direction of the ore body;

[0023] Step 24, the rock drilling and transport tunnel is arranged on the central axis of the ore block, connecting the disk belt transport tunnel and the return air tunnel;

[0024] Step 25, when the thickness of the ore body exceeds the maximum mining height of the mining equipment and the upper layer ore body is mined, a pan chute is arranged in the middle top and bottom columns at one end of the pan belt transport tunnel to allow the upper layer ore to slide to the belt conveyor in the middle connecting tunnel within the vein.

[0025] Preferably, the mining sequence between the ore blocks in the disk area includes: one-way mining from the air inlet side to the return air side along the direction of the ore body, and mining one by one between the ore blocks, that is, first mining the first-step ore room, and then mining the second-step ore pillars. After the mining of the ore blocks in the entire disk area is completed, the middle top and bottom pillars are finally mined.

[0026] Preferably, the order of mining between the middle sections and the layers includes: when mining a medium-thick ore body, when there are multiple layers in a middle section, alternate mining is adopted between the middle sections and the layers to ensure that the filling and mining of the stopes between the layers do not interfere with each other;

[0027] Preferably, the ore block recovery is specifically as follows: the bottom is fully pulled along the short axis of the ore block at the return air side end of the rock drilling and transportation tunnel, and two mining equipment are respectively arranged on both sides of the rock drilling and transportation tunnel to cooperate in withdrawing mining toward the air inlet end, ensuring that the equipment has more than two free surfaces during mining, thereby improving mining efficiency.

[0028] Preferably, the microwave rock breaking and ore dropping are specifically: microwaves are used to irradiate the hard rock on the mining surface to generate high temperature and break it, and then mining equipment is used to mine the irradiated hard rock.

[0029] Preferably, the mining equipment adopts a cantilevered tunnel boring machine, which is not limited to the pick type and tunneling method.

[0030] Beneficial effects: The proposed mining method has the following advantages:

[0031] a) Arranging two mining equipment in the stope for collaborative mining can complement each other in the supply of ore on the working face of the stope, so as to solve the problem of ore supply interruption caused by the difficulty in synchronizing microwave irradiation and mechanical cutting, and achieve the effect of stable ore output in the full cycle of mining in the stope;

[0032] b) The rock drilling and transportation tunnel serves as a connecting passage between the working face and the main transportation tunnel in the panel area, which prevents personnel and equipment from being directly exposed under the roof of a large area of ​​goaf, thus improving the operating safety of personnel and equipment underground;

[0033] c) The rock drilling and transportation tunnel is used as the air intake tunnel of the mining area. Clean air first reaches the working face of the mining area, ensuring a good working environment and helping to reduce the temperature generated by microwave irradiation on the working face;

[0034] d) Compared with the traditional drilling and blasting room-and-pillar method, this mining method has a smaller mining workload, a higher degree of mechanization, and greater safety;

[0035] e) When there are multiple layers in a middle section, alternate mining is adopted between the middle sections and the layers to ensure that the filling and mining in the mining areas between the layers do not interfere with each other, making it easier to form large-scale mining.

[0048] A specific embodiment provided by the present invention is as follows:

[0049] 1) Stope structure layout

[0050] According to the occurrence characteristics of the ore deposit, the ore deposit is divided into the middle section along the inclination, and the pan area is divided along the ore body strike in the middle section, and the ore blocks are further divided in the pan area. If the thickness of the ore body exceeds the maximum mining height of the mining equipment, the ore blocks are divided into layers. The oblique length of the middle section is determined by twice the economic transportation distance of the continuous conveying equipment in the mining field, which is generally 80 to 120m, and 15m to 20m wide top and bottom pillars are left between the middle sections; the pan area length is determined according to the reasonable transportation distance of the continuous conveying equipment in the pan area, which is 400 to 600m, and 15m inter-pan ore pillars are left between the pan areas. The ore blocks (mine rooms, ore pillars) are arranged at a pseudo-inclined angle of 45° along the direction of the ore body in the panel area. The pseudo-inclined ore blocks are arranged at a certain angle along the direction of the ore body in the panel area to ensure that the pseudo-inclined angle does not exceed the climbing capacity of the mining equipment. The width of the ore block is determined according to the stability of the surrounding rock, generally 15 to 20 meters. The height of the ore block is the thickness of the ore body. When the thickness of the ore body is greater than the maximum mining height of the mining equipment, it is divided into layers. The layer height is generally 4 to 6 meters.

[0051] 2) Cutting Engineering

[0052] The main mining and cutting projects include: middle section connecting tunnel, panel area belt transport tunnel 5, panel area auxiliary transport tunnel 6, middle section return air tunnel 1, rock drilling transport tunnel 7 and panel area chute 10.

[0053] The middle section connecting tunnel is divided into two types: the middle section connecting tunnel 2 inside the vein and the middle section connecting tunnel 9 outside the vein. The middle section connecting tunnel 9 outside the vein is arranged on both wings of the ore body as a channel for the transfer of mechanical equipment between adjacent layers of the middle section; the middle section connecting tunnel 2 inside the vein is arranged in the middle section top and bottom pillars 8, as a transportation tunnel and ventilation tunnel for personnel, materials, and ore between the middle sections. The panel belt transport tunnel 5 and the panel auxiliary transport tunnel 6 are arranged in the middle section top and bottom pillars 8 along the direction of the ore body, and the two are 8 to 10 meters apart. The adjacent middle section panels share a set of panel belt transport tunnels 5 and panel auxiliary transport tunnels 6.

[0055] All transverse mining and cutting projects are carried out using cantilevered tunnel boring machines, regardless of the cutter type and tunneling method, and the slope does not exceed the maximum climbing capacity of the tunnel boring machine.

[0056] 3) Mining sequence of three-dimensional stope structure

[0057] The mining sequence of the three-dimensional stope structure mainly includes the mining sequence between the middle layers and the mining sequence between the ore blocks in the panel area.

[0058] The order of mining between different middle sections: the middle sections are mined alternately, that is, the lower ore body in the lower middle section disk area is mined first, and then the lower ore body in the upper middle section disk area is mined. After the filling body of the first filling area 3 in the lower middle section disk area solidifies, the upper ore body is mined. After the upper ore body is mined, the second filling area 4 is filled.

[0059] The order of mining within the panel area is: one-way mining along the direction of the ore body, and the access blocks on both sides of the panel area belt transport tunnel 55 are mined simultaneously. The mining room is mined first and then the mining pillars. After the mining of the ore blocks in the entire panel area is completed, the panel area pillars are finally mined.

[0060] Mining sequence in the stope: excavate the mining tunnel along the central axis in the stope, which also serves as the ventilation channel for the stope and continuous transportation equipment. During the excavation process, two devices cooperate in the backward excavation and mining.

[0061] 4) Main mining process

[0062] ① Microwave rock breaking and ore falling

[0063] First, microwaves are used to irradiate and weaken the hard rock at the working face, and then the tunnel boring machine mines the weakened hard rock. Considering the presence of intercalated rocks in the ore body, in order to reduce the ore depletion rate and waste rock mixing rate, infrared ore and rock identification technology is used to specifically discard the excavation waste rock in situ.

[0064] ②Ore transportation

[0065] Ore transportation includes transportation within the mine, ore transportation in the disk area and ore transportation in the middle section. The ore cut in the mine is transferred to the transfer machine behind the equipment by the loading mechanism of the tunnel boring machine, and then transported out of the mine by the scraper conveyor arranged in the rock drilling and transportation tunnel 7; the ore in the disk area is transferred by the scraper conveyor to the belt conveyor in the disk area, and then transported by the belt conveyor to the belt conveyor in the middle section connecting tunnel, realizing continuous and stable transportation of the entire process of mine-disk area-middle section.

[0066] ③ Ventilation

[0067] Considering the dusty and high temperature environment of the excavation face during microwave-assisted mechanical rock breaking, a rock drilling and transportation tunnel 7 runs through the central axis of the mining field, and the transportation tunnel also serves as the ventilation tunnel for the entire mining field. The fresh air flow path is the panel area contact tunnel 2 → the panel area main transportation tunnel (panel area auxiliary transportation tunnel 6) → rock drilling and transportation tunnel 7 → mining face; the dirty air flow path is the mining face → the middle section return air tunnel 1, and ventilation is used to ensure that the temperature of the mining working face is below 26°.

[0068] ④Filling

[0069] After all mining in the mining area is completed, the whole tailings cemented filling body is used for filling. The filling height is the layered height, generally 4 to 6 meters, of which the lower 4 meters use a low-strength filling ratio and the upper 1 to 2 meters use a high-strength filling ratio.

[0070] 5) Pillar mining

[0071] The ore block recovery includes microwave irradiation, mechanical cutting and rock breaking, and ore dropping. Depending on the stability of the surrounding rock, the plate area pillars or inter-plate pillars are mined and filled in time after mining.

[0072] At the return air side end of the rock drilling and transport tunnel 7, the bottom is fully pulled along the short axis of the ore block, and two mining equipment are arranged on both sides of the rock drilling and transport tunnel 7 to cooperate in retreating toward the air inlet end, ensuring that the equipment has more than two free surfaces during mining, thereby improving mining efficiency.

[0073] In summary: The proposed mining method has the following advantages:

[0074] The dual-entry mining can complement each other in the supply of ore to the working face of the mine, so as to solve the problem of interrupted ore supply caused by the difficulty in synchronizing microwave radiation and mechanical cutting, and achieve the effect of stable mining in the whole cycle of the mine; the mining process and the ore-dropping process in the mine do not interfere with each other, and the continuity is strong; the rock drilling and transportation tunnel 7 serves as a connecting channel between the working face and the main transportation tunnel of the disk area, avoiding direct exposure of personnel and equipment to the roof of the large-area goaf, thereby improving the working safety of underground personnel and equipment; the rock drilling and transportation tunnel 7 serves as the air intake tunnel of the mine, and the clean air first reaches the working face of the mine, ensuring a good working environment, which is conducive to reducing the temperature generated by microwave irradiation on the working face; compared with the traditional drilling and blasting room and pillar method, this mining method has a smaller mining and cutting workload, a higher degree of mechanization, and stronger safety; when there are multiple layers in a middle section, alternating mining is adopted between the middle sections and the layers to ensure that the filling and mining of the mine between each layer do not interfere with each other, which is easier to form large-scale mining.

[0075] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
