Description

Technical Field

[0001] The present invention relates to a mining area tunnel and a layout method, in particular to a mining area tunnel and a layout method based on a public parking lot and a non-destructive filling mining method. Background Art

[0002] Coal still occupies a dominant position in China's energy structure, and its position will not change for a long time in the future. However, with the increase in the scale of coal mining and the increase in mining intensity, shallow coal resources are exhausted and mining depths are gradually deepening. At the same time, environmental and social problems caused by mining are also becoming increasingly serious. As an important part of the green mining system, backfill mining can reduce surface subsidence from the source and reduce the damage of mining to the working face and the surface. However, most of the existing backfilling methods have the problem of out-of-sync filling and mining processes, low work efficiency, and cannot guarantee the personal safety of operators. It is known that non-destructive backfilling mining technology realizes the continuous operation of coal mining and backfilling. It uses self-designed independent composite hydraulic supports for mining and filling to solve the above problems well, improve coal mining efficiency, and is a new and practical underground backfilling mining technology. However, the application scope of existing non-destructive filling mining technology is relatively limited. At the same time, the complex layout of the mining area tunnel system leads to high initial construction costs, which makes the overall layout of the mining area tunnel system complex and leads to high initial construction costs. In addition, the centralized scheduling design of materials and equipment is complex, which causes cross-interference of transportation routes and cannot ensure the overall efficiency and stability of the system. Summary of the Invention

[0003] In order to solve the shortcomings of the above technologies, the present invention provides a non-destructive filling mining area tunnel and layout method based on a public parking lot.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: a non-destructive filling mining area roadway based on a public parking lot, including a main transportation roadway and a main return air roadway. The non-destructive filling mining area roadway also includes an upper parking lot, and the public upper parking lot is used to coordinate the transportation of materials and equipment in the mining area during the entire coal mining cycle;

[0005] There are two tunnels between the main transport tunnel and the main return air tunnel, one for going uphill by rail and the other for transporting.

[0006] Along the coal seam direction, a track level tunnel and a public transport level tunnel are excavated on the side close to the main return air tunnel and the main transport tunnel respectively;

[0007] The track level tunnel is connected to the track uphill through the upper yard to form a transportation channel for materials and equipment;

[0008] The public transport level tunnel is connected with the transport uphill tunnel to form a public coal transport channel;

[0009] A public material tunnel is excavated along the end of the track tunnel and the public transport tunnel;

[0010] After the first mining face is mined and backfilled, the subsequent working face is put into use, and the transport level tunnel is retained as the track level tunnel for the subsequent working face. A new transport level tunnel is excavated along the other side of the subsequent working face as coal mining advances, and the new transport level tunnel is connected with the transport uphill.

[0011] As a preferred embodiment, the non-destructive filling mining area roadway also includes a lower parking lot;

[0012] The track goes up the mountain to connect with the lower yard;

[0013] The transportation up the mountain is also connected to the mining area coal bunker, which is connected to the lower yard;

[0014] The lower yard is connected to the main transport tunnel through the mining area transport stone gate.

[0015] A method for arranging tunnels in a non-destructive filling mining area based on a public parking lot comprises the following steps:

[0016] Step 1: Excavate two channels, one for track uphill and one for transport uphill, between the main transport tunnel and the main return air tunnel;

[0017] Step 2: excavate the track level tunnel and the public transport level tunnel respectively along the coal seam on the side close to the main return air tunnel and the main transport tunnel;

[0018] The track level tunnel is connected to the track uphill through the upper yard to form a transportation channel for materials and equipment, and the public transportation level tunnel is connected to the transportation uphill to form a public transportation channel for coal;

[0019] Step 3: Excavate a public material tunnel along the end of the track tunnel and the public transport tunnel, so that the track tunnel and the public transport tunnel are connected to the interface of the public material tunnel respectively. At this point, one wing of the mining area is initially formed;

[0020] Step 4: Divide the working face according to the specific design plan, excavate the transport level tunnel and connect it with the transport uphill, and the first mining working face is formed;

[0021] Step 5: After the first mining face is mined and filled, the subsequent working face is activated;

[0022] The transport tunnel is retained as the track tunnel for the subsequent working face, and a new transport tunnel is excavated along the other side of the subsequent working face as coal mining progresses. When coal mining is completed at the subsequent working face, the new transport tunnel is connected with the transport uphill tunnel;

[0023] Step 6: Continue to arrange the subsequent working faces with reference to step 5 until the coal mining and filling tasks in the mining area are completed.

[0024] As a preferred option, for the first mining working face, the required equipment and materials are transported through the transportation route of the main transport tunnel → mining area transport stone gate → lower yard → track up the mountain → upper yard, and finally transported to the track level tunnel for installation or filling.

[0025] As a preferred option, for the first mining working face, the mined coal is sent out via the transportation route of the transport tunnel → transport up the mountain → mining area coal bunker, and loaded at the lower yard of the mining area, and finally transported out from the main transportation tunnel.

[0026] As a preferred embodiment, for the connecting working face, when the equipment is relocated, the equipment in the rail level tunnel is relocated and installed in the transport level tunnel. At this time, the transport level tunnel serves as the rail level tunnel for the connecting working face, and belt conveyors are laid in the public material tunnel and the transport level tunnel at the same time. At this time, the equipment and material transfer route is the main transport tunnel → mining area transport stone gate → mining area lower parking lot → rail uphill → mining area upper parking lot → rail level tunnel → public material tunnel, and finally transferred to the transport level tunnel for installation or filling.

[0027] As a preferred option, for the subsequent working face, since the new transport level tunnel is excavated as it is mined, the coal transportation route is new transport level tunnel → public material tunnel → public transport level tunnel → transportation up the mountain → mining area coal bunker, and loading at the lower parking lot of the mining area, and finally transported out from the main transport tunnel.

[0028] The present invention discloses a non-destructive filling mining area roadway and layout method based on a public parking lot. It adopts a public upper parking lot layout method and combines non-destructive filling mining technology to improve the efficiency of mining and filling connection while simplifying the roadway layout, so that the public upper parking lot is responsible for the transportation of materials and equipment throughout the life cycle of coal mining, realizing the integration of the whole process of material and equipment transportation, reducing investment costs, shortening the construction period, and significantly improving the overall efficiency and stability of the system. The optimized non-destructive filling mining method can adapt to different mining scales and geological structures by flexibly adjusting transportation nodes to adapt to mining needs in various situations, thereby enhancing the applicability of the non-destructive filling mining method under different mining conditions and providing safe and reliable technical guarantees for large-scale mining under complex geological conditions.

[0036] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] The present invention discloses a non-destructive filling mining area roadway and layout method based on a public parking lot, which realizes the transportation of materials and equipment in the mining area during the entire coal mining cycle through the public upper parking lot layout, and improves the efficiency of the working face connection by combining non-destructive filling mining technology. Figure 1 and Figure 2 The wing of the mining area shown is then formed Figure 3 and Figure 4 As shown in the first mining face, after the first mining face is mined and filled, the subsequent working face is used, and a new transport level tunnel (i.e., new transport level tunnel 14) is excavated as the coal mining advances, thereby obtaining the following Figure 5 and Figure 6 The illustrated non-destructive filling mining tunnel allows for simultaneous filling and mining operations. This system creates a material and equipment transport channel and a common coal transport channel, centrally dispatching the transportation of materials and equipment within the mining area from the upper yard. This simplifies the overall tunnel layout, reduces initial investment costs, shortens the construction period, and ensures the continuity of mining and filling operations. Furthermore, centralized control facilitates real-time monitoring of transport status, enabling rapid response to abnormalities such as transport route blockages and enhancing the transportation system's emergency dispatch capabilities.

[0038] like Figure 5 and Figure 6 As shown, the non-destructive filling mining area tunnel includes a main transport tunnel 1, a main return air tunnel 2, an upper parking lot 8, a middle parking lot 9, and a lower parking lot 5;

[0039] There are two tunnels, track uphill 6 and transport uphill 7, between the main transport tunnel 1 and the main return air tunnel 2;

[0040] The main transport tunnel 1 is the main passage connecting the main and auxiliary shafts on the ground, and is also the air inlet. Preferably, a mining area transport stone gate 3 is provided between the main transport tunnel 1 and the lower parking lot 5 to facilitate the transportation of equipment and materials.

[0041] The main return air duct 2 is a return air duct that leads directly to the ground, which is used to meet the air needs of employees during normal underground operations. Preferably, a mining area return air door 4 is installed between the main return air duct 2 and the mining area tunnel to facilitate the control and adjustment of the airflow direction, air volume and air pressure in the mining area.

[0042] Furthermore, along the coal seam, a track tunnel 10 and a public transport tunnel 11 are excavated on one side close to the main return air tunnel 2 and the main transport tunnel 1 respectively;

[0043] The track tunnel 10 is mainly used for material transportation and auxiliary transportation. The track tunnel 10 is connected to the track uphill 6 through the upper yard 8, and the track uphill 6 is connected between the lower yard 5 and the upper yard 8 to form a transportation channel for materials and equipment.

[0044] The public transport tunnel 11 is mainly used for mineral transportation. The public transport tunnel 11 is directly connected to the transport uphill 7 to form a public coal transportation channel.

[0045] Furthermore, a public material tunnel 12 is provided between the track tunnel 10 and the public transport tunnel 11, so that the track tunnel 10 and the public transport tunnel 11 are respectively connected to the interfaces of the public material tunnel 12, thus a wing of the mining area is initially formed.

[0046] Furthermore, the transport tunnel 13 is excavated to connect it with the transport uphill tunnel 7, and the first mining working face is formed.

[0047] After the initial mining face was mined and backfilled, the subsequent working face was activated. Transport tunnel 13 was retained as the track tunnel for the subsequent working face, and a new transport tunnel 14 was excavated along the other side of the subsequent working face as mining progressed. Notably, the completion of mining at the subsequent working face coincided with the completion of new transport tunnel 14 and the connection with transport tunnel 7.

[0048] In addition, the transport uphill 7 is also connected to the mining area coal bunker 15, and the mining area coal bunker 15 is connected to the lower parking lot 5 to realize the transportation of mined coal from the lower parking lot 5 and the main transport tunnel 1.

[0049] Regarding the above-mentioned non-destructive filling mining area roadway, the present invention also discloses a method for arranging the non-destructive filling mining area roadway, comprising the following steps:

[0050] Step 1: Excavate two passages, namely, track uphill 6 and transport uphill 7, between the main transport tunnel 1 and the main return air tunnel 2;

[0051] Step 2: Along the coal seam, excavate a track tunnel 10 and a public transport tunnel 11 on one side close to the main return air tunnel 2 and the main transport tunnel 1, respectively, so that the track tunnel 10 is connected to the track uphill 6 through the upper parking lot 8 to form a transportation channel for materials and equipment, and the public transport tunnel 11 is connected to the transport uphill 7 to form a public transportation channel for coal;

[0052] Step 3: Excavate the public material tunnel 12 along the end of the track tunnel 10 and the public transport tunnel 11, so that the track tunnel 10 and the public transport tunnel 11 are connected to the interface of the public material tunnel 12, thereby forming a preliminary wing of the mining area;

[0053] Step 4: Divide the working face according to the specific design plan, excavate the transport level tunnel 13 and connect it with the transport uphill, and the first mining working face is formed.

[0054] For the first mining working face, the equipment and materials required are transported through the transportation route of the main transport tunnel 1 → mining area transport stone gate 3 → lower parking lot 5 → rail uphill 6 → upper parking lot 8 and finally transported to the rail level tunnel 10 for installation or filling.

[0055] The mined coal is transported through the transport tunnel 13 → transported uphill 7 → transported to the mining area coal bunker 15, and loaded into trucks at the lower mining area yard 5, and finally transported out through the main transport tunnel 1;

[0056] Step 5: After the first mining face is mined and filled, the subsequent working face is activated;

[0057] The transport tunnel 13 is retained as the track tunnel for the subsequent working face, and a new transport tunnel 14 is excavated along the other side of the subsequent working face as coal mining progresses. When coal mining is completed at the subsequent working face, the new transport tunnel 14 is connected with the transport uphill tunnel 7;

[0058] When the equipment is relocated, the equipment in the track tunnel 10 is relocated and installed in the transport tunnel 13. At this time, the transport tunnel serves as the track tunnel for the subsequent working face, and at the same time, belt conveyors are laid in the public material tunnel 12 and the transport tunnel 13 (the track tunnel for the subsequent working face). At this time, the equipment and material transfer route is the main transport tunnel 1 → the mining area transport stone gate 3 → the mining area lower parking lot 5 → the track uphill 6 → the mining area upper parking lot 8 → the track tunnel 10 → the public material tunnel 12, and finally transferred to the transport tunnel 13 (the track tunnel for the subsequent working face) for installation or filling.

[0059] Since the new transport tunnel 14 is excavated as the coal is mined, the coal transportation route at this time is new transport tunnel 14 → public material tunnel 12 → public transport tunnel 11 → transport uphill 7 → mining area coal bunker 15, and then loaded at the lower parking lot 5 of the mining area, and finally transported out through the main transport tunnel 1;

[0060] Step 6: Continue to arrange the subsequent working faces with reference to step 5 until the coal mining and filling tasks in the mining area are completed.

[0061] Thus, the present invention realizes the centralized dispatch of materials and equipment through the arrangement of a public upper parking lot, simplifies the overall layout of the system, reduces the initial construction cost, shortens the transportation distance, effectively avoids the cross-interference of different transportation routes, ensures that the filling materials and equipment accurately reach the working face, ensures the timely support of the top rock layer by the filling body, effectively suppresses the damage of the overburden and the surface subsidence, and reduces the disturbance of mining to the surface facilities and the ecological environment. The non-destructive filling mining method after the optimization of the public parking lot arrangement significantly improves the efficiency and stability of the entire system. At the same time, the public parking lot arrangement can be adapted to different mining scales and coal seam structures. By flexibly adjusting the position of the public parking lot to meet the mining needs of coal seams under different geological conditions, the coal resources that are classified as unminable due to mining risks or geological conditions are safely released and converted into minable resources, providing a guarantee for the efficient and safe mining of coal resources under complex geological conditions.

[0062] The above embodiments are not limitations of the present invention, and the present invention is not limited to the above examples. Any changes, modifications, additions or substitutions made by technicians in this technical field within the scope of the technical solution of the present invention also fall within the scope of protection of the present invention.
