Description

Technical Field

[0001] This application relates to the technical field of underground ore deposit mining, and particularly to a rail - trackless collaborative mine transportation system and method based on elevation ore passes. Background Art

[0002] The ore pass system is one of the most important projects in the underground mining of metal ore deposits. At present, most of the ore pass systems in metal underground mines adopt the design mode of traditional high - level centralized ore passes (main ore passes) beside vertical shafts. The transportation of each intermediate level is carried out by rail mine cars. The ore mined from the stope is transported to the intermediate - level ore pass for unloading by a battery locomotive towing the mine car, and then the ore in the ore pass is discharged into the rail mine car for transportation at the next intermediate level by an ore draw - off machine. Moreover, with the continuous improvement of the degree of mine mechanization, especially the application of mining equipment such as trackless equipment, the stoping effect has been greatly improved.

[0003] However, due to the large number of stope operation points underground, the current design mode of traditional high - level centralized ore passes beside vertical shafts has problems such as many ore - drawing operation points, many operating personnel and equipment, a relatively long distance between the intermediate - level ore pass and the ore - drawing point, and low efficiency of loading and transportation equipment. The existing intermediate - level transportation system cannot match the current mining capacity requirements and cannot achieve efficient ore operation. Summary of the Invention

[0004] In order to improve the problem that the existing intermediate - level transportation system cannot match the current mining capacity requirements and cannot achieve efficient ore operation, this application provides a rail - trackless collaborative mine transportation system and method based on elevation ore passes.

[0005] The rail - trackless collaborative mine transportation system and method based on elevation ore passes provided by this application adopt the following technical solutions: The rail - trackless collaborative mine transportation system based on elevation ore passes provided in the first aspect of this application adopts the following technical solutions: A rail - trackless collaborative mine transportation system based on elevation ore passes includes an ore - drawing level and a transportation level; The ore - drawing level includes: Cross - cut transportation roadways, with multiple ones arranged perpendicular to the ore - body strike; Out - of - vein transportation roadways, connecting between two adjacent cross - cut transportation roadways; Loading headings, one end of which is connected to the out - of - vein transportation roadway and the other end extends to one side of the ore - body; and Gully roadways, arranged along the ore - body strike and located below the ore - body; The transportation level includes: Main transportation intermediate levels, arranged below the gully roadways; A number of mining area ore passes are vertically excavated between the trench roadway and the main haulage level. Ore is transported by a load-haul-dump (LHD) machine to the mining area ore pass for unloading, and is loaded into ore cars by a vibrating ore draw machine at the main haulage level. The ore is concentrated at the main haulage level for ore drawing and transportation to the concentrator.

[0006] Furthermore, the mining area ore pass is arranged between two adjacent ore blocks.

[0007] Furthermore, the upper section of the mining area ore pass is excavated completely vertically, and the lower section is excavated obliquely and guided to the main haulage level.

[0008] Furthermore, the inclination angle of the lower section of the mining area ore pass does not exceed 45°.

[0009] Furthermore, a steel ore chute is laid on the material guiding inclined plane of the lower section of the mining area ore pass.

[0010] Furthermore, the height that the steel ore chute extends to the vertical wall of the upper section of the mining area ore pass is not less than 50 cm.

[0011] Furthermore, tracks for the operation of transport vehicles are arranged in the haulage level to construct a rail system; no tracks are arranged in the ore extraction level, and the LHD machine transports the ore from the ore loading drift to the mining area ore pass through the cross-cut roadway outside the vein in the ore loading drift to construct a trackless system.

[0012] Furthermore, the distance between two adjacent ore loading drifts is 10 - 15 m.

[0013] Furthermore, the oblique intersection angle between the ore loading drift and the cross-cut roadway outside the vein is 45° - 90°.

[0014] A rail-trackless collaborative mine transportation method provided in the second aspect of the present application adopts the following technical solution: A rail-trackless collaborative mine transportation method based on an elevation ore pass, based on the above-mentioned rail-trackless collaborative mine transportation system based on an elevation ore pass, includes the following steps: S1. Construct the transportation system according to any one of claims 1 - 9; S2. Start the up-dip mining and ore caving in the stope, and the ore falls into the trench roadway; S3. The LHD machine enters the ore loading drift corresponding to the mining area ore pass, clears the ore on the periphery of the mining area ore pass and discharges it into the mining area ore pass; S4. The LHD machine enters the ore loading drift that is not corresponding to the mining area ore pass, transports the ore in the trench roadway to the mining area ore pass for unloading; S5. The mining area ore pass drops the ore to the main haulage level, and at the main haulage level, it is loaded into ore cars by a vibrating ore draw machine, and the ore is concentrated at the main haulage level for ore drawing and transportation to the concentrator.

[0015] In summary, the beneficial technical effects of this application are as follows: 1. By arranging the draw shaft in the stope between two adjacent ore blocks, on the ore-drawing level, the load-haul-dump (LHD) machine only needs to enter the loading side road, load the ore at the corresponding point, then reverse from the loading side road to the off-vein transportation roadway, and then enter the main loading road, and unload the ore into the draw shaft. The draw shaft uniformly lowers the ore to the main haulage level, which can significantly shorten the traveling path of the LHD machine on the ore-drawing level, reduce the number of ore transfer times, and eliminate the need to additionally arrange ore cars on the ore-drawing level. And through the reasonable planning of the traveling paths of multiple LHD machines, the number of LHD machines that can be accommodated at most on the same ore-drawing level can be significantly increased, thereby improving the ore transfer efficiency. In this way, the transfer of ore from each level to the main haulage level can be realized, which can improve the ore-drawing capacity of the stope, reduce the ore transfer links at the same time, and meet the current mining capacity requirements; 2. By setting one section above the transportation level as the trackless ore-drawing equipment level, i.e., the LHD machine ore-drawing level, and the main haulage level in the transportation level can still continue to use the existing rail-type intermediate haulage roadway in the mine. Through this key facility of the draw shaft, the effective connection and coordinated operation between the ore-drawing level and the transportation level are realized, and the advantages of rail-type and trackless ore-drawing equipment are fully combined, thus ensuring the high efficiency and smoothness of the entire process from ore mining to transportation; 3. The transportation system of this application can be applied to steeply inclined medium-thick ore bodies that are in the process of transforming to trackless mining. This rail-trackless coordinated transportation technology is an optimization of the bottom structure of the stope and the development and preparatory system. Its function is to ensure the continuous production of the mine and promote the transition of the mine to trackless and mechanized under the current situation that a certain scale and relatively perfect rail-type development system has been formed in some large and medium-sized mines, with significant economic benefits; 4. Through the setting of the ore chute steel plate groove, on the one hand, the ore dropping resistance of the inclined part at the lower section of the draw shaft can be greatly reduced, ensuring that the ore can flow smoothly in the inclined part at the lower section of the draw shaft and avoiding blockage and jamming; on the other hand, the ore chute steel plate groove can be used as a protective structure for the inclined part at the lower section of the draw shaft, which can significantly reduce the impact on the inclined part at the lower section of the draw shaft during the rapid ore dropping in the vertical part at the upper section of the draw shaft, maintain the stability and integrity of the structure of the inclined part at the lower section of the draw shaft, and effectively avoid the instability and collapse of the inclined part at the lower section of the draw shaft, resulting in the drift of the connection point with the main haulage level.

[0018] Next, the technical solutions of the present application will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0019] The embodiment of the present application discloses a rail - trackless collaborative mine transportation system based on an elevation ore pass. Refer to Figure 1 and Figure 2 , which includes an ore extraction level and a transportation level; Among them, the ore extraction level includes: Cross-cut haulage roadways 1, multiple of which are arranged perpendicular to the strike of the ore body 7. Generally, the distance between adjacent two cross-cut haulage roadways 1 is 100m - 200m.

[0020] Off-vein haulage roadway 2, which is connected between adjacent two cross-cut haulage roadways 1, and the connection part of the off-vein haulage roadway 2 and the cross-cut haulage roadway 1 needs to be enlarged to facilitate the turning of equipment such as load-haul-dumpers.

[0021] Ore loading drifts 4, one end of which is connected to the off-vein haulage roadway 2 and the other end extends to one side of the ore body 7. The distance between adjacent two ore loading drifts 4 is 10 - 15m, and the oblique intersection angle between the ore loading drift 4 and the off-vein haulage roadway is 45° - 90°; similarly, the surrounding rock 3 on one side of the connection part between the ore loading drift 4 and the off-vein haulage roadway 2 needs to be processed into an arc transition surface to facilitate the turning in and out of the load-haul-dumper.

[0022] Cut-off drift 9, which is arranged along the strike of the ore body 7 and is located below the ore body 7. Specifically, it should be connected to each ore loading drift 4 to facilitate the load-haul-dumper to shovel out the ore 8.

[0023] Among them, the transportation level includes: Main haulage level, which is arranged below the cut-off drift 9.

[0024] In addition, it should be particularly noted that refer to Figure 1 and Figure 2, there are several stope ore passes 5 excavated vertically between the trench roadway 9 and the main haulage level. The stope ore passes 5 are arranged between two adjacent ore blocks. The mined ore 8 is transported by a load-haul-dump (LHD) vehicle to the stope ore pass 5 for unloading, and is loaded into ore cars by a vibrating ore drawgear at the main haulage level, and is concentrated at the main haulage level for ore drawing and transportation to the concentrator.

[0025] Specifically, tracks for the operation of transport vehicles are arranged at the haulage level to construct a rail system; no tracks are arranged at the ore extraction level, and the LHD vehicle transports the ore 8 from the ore loading drift 4 through the off-vein haulage roadway 2 to the stope ore pass 5 to construct a trackless system.

[0026] Meanwhile, for the convenience of distinction, the ore loading drift 4 corresponding to the stope ore pass 5 is the main ore loading drift 41, and the other ore loading drifts 4 are the side ore loading drifts 42. There are multiple side ore loading drifts 42 and they are arranged on both sides of the main ore loading drift 41. Moreover, regarding the oblique intersection angle between the aforesaid ore loading drift 4 and the off-vein haulage roadway, it should be clear that all the side ore loading drifts 42 are inclined in the direction away from the main ore loading drift 41, so that after the LHD vehicle loads the ore 8, it can conveniently reverse from the side ore loading drift 42 into the off-vein haulage roadway 2, and then through the off-vein haulage roadway 2 and the main ore loading drift 41, transfer the ore 8 to the stope ore pass 5 for unloading. Based on the same requirement consideration, the aforementioned arc transition surface should also be arranged on the surrounding rock 3 on the side of the connecting part of the ore loading drift 4 and the off-vein haulage roadway that is away from the main ore loading drift 41.

[0027] Thus, by setting the above-mentioned transportation system, the original underground transportation method of unloading from each level to the main stope ore pass system respectively can be changed to unloading from each level to the stope ore pass 5, and then through ore cars for centralized transportation at the main haulage level. Moreover, the stope ore passes 5 are arranged between two adjacent ore blocks. The ore 8 is transported by an LHD vehicle to the stope ore pass 5 for unloading, and is loaded into ore cars by a vibrating ore drawgear at the main haulage level, and is concentrated at the main haulage level for ore drawing and transportation to the concentrator, which can greatly shorten the walking path of the LHD vehicle at the ore extraction level. Through the reasonable planning of the driving paths of multiple LHD vehicles, the number of LHD vehicles that can be accommodated at the same ore extraction level can be significantly increased, thereby improving the operation efficiency of the ore 8. In this way, the transfer of the ore 8 from each level to the main haulage level can be realized, which can improve the ore extraction capacity of the stope, reduce the transfer links of the ore 8 at the same time, and meet the current mining capacity requirements.

[0028] Moreover, compared with the original stope bottom structure, the optimized stope bottom structure of the transportation system in this application adopts the ore drawing form of the mining area ore pass 5. One ore pass 5 is set between two adjacent ore blocks. A section above the transportation level is set as the trackless ore drawing equipment level, that is, the load-haul-dump (LHD) vehicle ore drawing level. The LHD vehicle transports the ore 8 through the out-of-vein transportation roadway 2 in the ore loading drift 4 to the mining area ore pass 5, and then directly drops it to the main transportation crossheading in the main transportation level through the mining area ore pass 5. The main transportation crossheading in the transportation level can continue to utilize the existing rail crossheading in the mine. Through this key facility of the mining area ore pass 5, the effective connection and coordinated operation between the ore drawing level and the transportation level are realized, thus ensuring the high efficiency and smoothness of the entire process from ore mining to transportation.

[0029] Therefore, the transportation system of this application can be applied to steeply inclined medium-thick ore bodies 7 that are in the process of transforming to trackless mining. This rail-trackless coordinated transportation process is an optimization of the stope bottom structure and the development and tunneling system. Its function is to ensure the continuous production of the mine under the current situation that a certain scale and relatively complete rail development system have been formed in some large and medium-sized mines, and to promote the transition of the mine to trackless and mechanized operations, with significant economic benefits.

[0030] In addition, to ensure the ore dropping efficiency of the mining area ore pass 5, referring to Figure 2 , the upper section of the mining area ore pass 5 is excavated completely vertically, and the lower section is excavated obliquely and guided to the main transportation crossheading, and the inclination angle of the lower section of the mining area ore pass 5 does not exceed 45°. Thus, on the basis of ensuring the ore dropping efficiency of the mining area ore pass 5, the lower section of the mining area ore pass 5 can be inclined to facilitate the connection between the trench roadways 9 at different positions and the main transportation crossheading, with a wider scope of application.

[0031] And to ensure that the ore 8 can be smoothly guided to the main transportation crossheading in the lower section of the mining area ore pass 5.

[0032] In another feasible embodiment, referring to Figure 3 , a chute steel plate groove 10 is laid on the material guiding inclined plane of the lower section of the mining area ore pass 5, and the height of the chute steel plate groove 10 extending to the vertical wall of the upper section of the mining area ore pass 5 is not less than 50 cm. Specifically, the chute steel plate groove 10 is generally in a "L" shape with an obtuse inner angle and a cross-section in a "U" shape; and the chute steel plate groove 10 can be fixed to the inner wall of the mining area ore pass 5 by means of anchor bolts, etc.

[0033] Thus, through the setting of the ore chute steel plate groove 10, on the one hand, the ore dropping resistance of the ore 8 in the inclined part of the lower section of the stope ore pass 5 can be greatly reduced, ensuring the smooth flow of the ore 8 in the inclined part of the lower section of the stope ore pass 5 and avoiding blockage and jamming. On the other hand, the ore chute steel plate groove 10 can serve as a protective structure for the inclined part of the lower section of the stope ore pass 5, significantly reducing the impact on the inclined part of the lower section of the stope ore pass 5 when the ore drops rapidly in the vertical part of the upper section of the stope ore pass 5, maintaining the stability and integrity of the structure of the inclined part of the lower section of the stope ore pass 5, and effectively avoiding the instability and collapse of the inclined part of the lower section of the stope ore pass 5, resulting in the drift of the connection point with the main transportation level.

[0034] The embodiment of the present application discloses a rail - trackless collaborative mine transportation method based on an elevation ore pass. Based on the above - mentioned rail - trackless collaborative mine transportation system based on an elevation ore pass, referring to Figure 1 and Figure 2 , it includes the following steps: S1. Construct the transportation system as described above; S2. Start the up - mining and ore caving in the stope, and the ore 8 falls into the trench roadway 9; S3. The load - haul - dump machine enters the ore loading access 4 corresponding to the stope ore pass 5, specifically referring to the main ore loading road 41, and clears and drops the ore 8 on the periphery of the stope ore pass 5 into the stope ore pass 5; S4. The load - haul - dump machine enters the ore loading access 4 that is not corresponding to the stope ore pass 5, specifically referring to the side ore loading road 42, and transports the ore 8 in the trench roadway 9 to the stope ore pass 5 for unloading; S5. The stope ore pass 5 drops the ore 8 to the main transportation level. At the main transportation level, the ore is loaded into the ore car through a vibrating ore draw device, and the ore is concentrated at the main transportation level for ore drawing and transportation to the concentrator.

[0035] Its specific transportation route is: ore mined from the stope → load - haul - dump machine ore loading → side ore loading road 42 → out - of - vein transportation passage → main ore loading road 41 → stope ore pass 5 → main transportation level → concentrator.

[0036] Thus, by arranging the stope ore pass 5 between two adjacent ore blocks, on the ore drawing level, the LHD only needs to enter the ore loading side road 42, load the ore 8 at the corresponding position, then retreat from the ore loading side road 42 to the out-of-vein transportation roadway, and then enter the main ore loading road 41, and unload the ore 8 into the stope ore pass 5. The stope ore pass 5 uniformly lowers the ore 8 to the main transportation level, which can significantly shorten the traveling path of the LHD on the ore drawing level, reduce the transfer times of the ore 8, and eliminate the need to additionally arrange ore cars on the ore drawing level. Moreover, through the reasonable planning of the traveling paths of multiple LHDs, the number of LHDs that can be accommodated at most on the same ore drawing level can be significantly increased, thereby improving the operation efficiency of the ore 8. In this way, the transfer of the ore 8 from each level to the main transportation level can be realized, which can improve the ore drawing capacity of the stope, reduce the transfer links of the ore 8 at the same time, and meet the current mining capacity requirements.

[0037] The implementation principle of a rail - trackless collaborative mine transportation system based on an elevation ore pass in an embodiment of this application is as follows: By arranging the stope ore pass 5 between two adjacent ore blocks, on the ore drawing level, the LHD only needs to enter the ore loading side road, load the ore 8 at the corresponding position, then retreat from the ore loading side road to the out-of-vein transportation roadway, and then enter the main ore loading road, and unload the ore 8 into the stope ore pass 5. The stope ore pass 5 uniformly lowers the ore 8 to the main transportation level, which can significantly shorten the traveling path of the LHD on the ore drawing level, reduce the transfer times of the ore 8, and eliminate the need to additionally arrange ore cars on the ore drawing level. Moreover, through the reasonable planning of the traveling paths of multiple LHDs, the number of LHDs that can be accommodated at most on the same ore drawing level can be significantly increased, thereby improving the operation efficiency of the ore 8. In this way, the transfer of the ore 8 from each level to the main transportation level can be realized, which can improve the ore drawing capacity of the stope, reduce the transfer links of the ore 8 at the same time, and meet the current mining capacity requirements.

[0038] Compared with the original stope bottom structure, the optimized stope bottom structure of the transportation system in this application adopts the ore drawing form of the stope ore pass 5. One stope ore pass 5 is arranged between two adjacent ore blocks. A section above the transportation level is set as the trackless ore drawing equipment level, that is, the LHD ore drawing level. The LHD transports the ore 8 through the out-of-vein transportation roadway 2 to the stope ore pass 5 in the ore loading drift 4, and then directly lowers it to the main transportation level roadway through the stope ore pass 5; and the main transportation level in the transportation level can continue to use the existing rail-type middle-section transportation roadway of the mine. Through this key facility of the stope ore pass 5, the effective connection and collaborative operation between the ore drawing level and the transportation level are realized, and the advantages of rail - trackless mining equipment are fully combined, thus ensuring the high efficiency and smoothness of the entire process from ore mining to transportation of the ore 8.
