Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a method for utilizing underground space in a mine. Background Art

[0002] The mining methods used in underground mines are generally divided into three categories, namely, open-pit method, caving method and backfill method. In underground mines that use caving method and backfill method, the underground goaf is filled with surrounding rock or backfill and cannot be used. In underground mines that use open-pit method, the surrounding rock is relatively stable, so a large amount of underground space is reserved for development and utilization.

[0003] At present, the relevant management departments regard the goaf formed by open-field mining as a potential disaster hazard and require mines to fill the goaf, wasting a lot of available underground space. In addition, the research on how to utilize underground spaces such as mine chambers and goafs is still in the research stage in China. Although three development and utilization models have been proposed, namely underground storage type, sewage disposal type and scientific and educational type, all of the above three utilization models have great limitations and there is no actual application scenario in China at present. Summary of the invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a method for utilizing underground space in mines to solve the problems raised in the above-mentioned background technology. The present invention utilizes the underground space of mines to develop and utilize to build data centers, and includes underground goafs and chambers. The underground space of mines is reinforced and supported to enhance the stability of the utilized underground space. At the same time, the protection effect of each server is improved with the help of the data center server mounting frame.

[0005] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical solutions: a method for utilizing underground space in a mine, including network laying, building a data center server installation frame, and building a server cluster, a drainage system, a refrigeration system, a ventilation system, and a monitoring and surveillance system; the network laying is for communication network access to be built to the underground space of the mine, using a fiber optic high-speed network, the server cluster is a large-scale server, and the data center server is installed in the underground space of the mine, and the data center server stores, calculates, and exchanges data; and each data center server is supported and fixed by an independent installation frame, and the installation frame is fixed to the point column and the ground area at the same time during the construction of the underground space of the mine.

[0006] Furthermore, when the drainage system is constructed, for underground mines that can drain by gravity, the drainage system is various drainage ditches and drainage holes, and for underground mines that cannot drain by gravity, the drainage system is a mechanical drainage pump station and drainage pipelines.

[0007] Furthermore, the refrigeration system is divided into an air-cooled refrigeration system and a water-cooled refrigeration system. The air-cooled refrigeration system cools the server by cold air, and the air-cooled refrigeration system is connected to the top of each data center server mounting rack through an air-cooling pipe. The water-cooled refrigeration system cools the data center server by circulating low-temperature water.

[0008] Furthermore, the ventilation system utilizes the mine's original ventilators, ventilation tunnels, air doors, air bridges, air inlet shafts, air return shafts, etc., or newly excavated ventilation shafts and other facilities, and adopts an exhaust ventilation method to send fresh surface air flow into the underground space underground, thereby ensuring that the air in the data center in the underground space underground is fresh.

[0009] Furthermore, the monitoring system utilizes the existing video monitoring systems, wind speed and pressure sensors, environmental monitoring systems, and ground pressure sensors of some mines to monitor the operation of the mine's underground data center in real time through the monitoring system.

[0010] Furthermore, the video surveillance system includes a video surveillance camera, and the environmental monitoring system includes CO, NO2, O2 sensors, etc.

[0011] Furthermore, the installation steps of each data center server include: first fixing the bottom of each mounting frame in a preset area, using fixing bolts to fit the fixing plates on both sides of the mounting frame to the surface of the point column closest to the side, and finally placing the data center server on the surface of the bottom plate, and using the top plate to fix one side of the data center server against it.

[0012] Furthermore, the external low-temperature airflow is transported to the interior of the air-cooling pipe through the air-cooling refrigeration system, and one side of the low-temperature airflow is transported to the cooling component on the top of each mounting rack through the air-cooling pipe. The interior of the cooling component transports part of the low-temperature airflow to the interior of the thermal interlayer through the first air inlet box, and at the same time, part of the low-temperature airflow is blown downward toward the surface of the data center server through each guide fan at the bottom through the second air inlet box.

[0013] Furthermore, the end of the screw is pressed against the middle position of one side of the top plate, and the end of the screw is movably connected to the surface of the top plate using a bearing, and the hand wheel is turned to control the movement of the top rod until it is pressed against the top and bottom of one side of the data center server.

[0014] Furthermore, for the mining of the mine room, after the mining is completed, the areas with poor stability of the top plate are used for waste rock cementation filling using waste rock from the production period and waste rock after photoelectric ore dressing. Other areas with stable surrounding rock or good support are used as underground space, and this part of the well-supported area is built and utilized as a data center computer room.

[0015] Beneficial effects of the present invention:

[0016] 1. The method for utilizing underground space in mines can develop and utilize the underground space in mines to build data centers, and includes underground goafs and chambers. The stability of the underground space in mines is enhanced by reinforcing and supporting the underground space.

[0017] 2. This utilization method makes it possible for underground space in mines to no longer be treated as a potential disaster hazard, and fully and effectively utilize underground space. The technical solution of the present invention has wide applicability and feasibility, and the utilization of underground space in mines is no longer limited to the utilization model of traditional research. At the same time, after the mine stops mining, it also finds a new source of income for the closed mine.

[0018] 3. Each data center server in the data center constructed in the mine underground space utilization method is installed and supported by an outer mounting frame, thereby providing targeted locking and protection for each data center server, and directly blowing the heat dissipation airflow evenly from around the data center server, thereby improving the efficiency and uniformity of heat dissipation.

DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0026] See also Figures 1 to 5 The present invention provides the following technical solutions: a method for utilizing underground space in a mine, which realizes the utilization of underground space in a goaf of a pre-controlled top pillar mining method. This embodiment provides the following specific steps:

[0027] The block is 100m long along the strike and 100m long along the dip. A 4m wide pillar 6 is left between the blocks. Top and bottom pillars 4 are arranged along the strike, and the segmented transport tunnel is arranged in the top and bottom pillars 4. The mine room is arranged horizontally along the strike in the block, and regular point pillars 7 are left in the mine room. The size of point pillars 7 is generally 4m×4m, and they are arranged at intervals of 8m along the strike and dip. The mining field structural parameters can be adjusted appropriately according to the actual situation in the later stage: when the surrounding rock conditions of the mining field roof 25 are unstable, 5m isolation pillars are left between adjacent mining rooms. And measures can be taken to increase the stress area of ​​point pillars 7 - leave 5m×5m point pillars 7, or take measures to reinforce point pillars 7 - construct a circle of steel mesh around point pillars 7, and apply a certain stress to restore point pillars 7 to a three-way stress state.

[0028] Mining in the ore block is to withdraw from the center of the cutting tunnel to both ends, and from top to bottom along the cutting uphill 2, and leave spacers 6 and point columns 7 according to the design requirements and the specific geological conditions of the mine room. That is, a horizontal tunnel is cut from the end of the cutting uphill 2 to both ends, and a return air port 8 is cut at the end of the horizontal tunnel. When a smooth ventilation circuit is formed in the mine room, a new horizontal cutting groove is pulled from the end of the cutting uphill 2 at an interval of about 12m for mining. During the mining process, the next horizontal cutting groove is pulled at an interval of about 12m, and the mining is completed in sequence; during the mining process, a regular ore pillar of 4m×4m is left at an interval of 8m along the strike and 8m along the dip, and continuous spacers 6 and top and bottom pillars 4 are left around the ore block to facilitate the ventilation of the mining field and the management of the roof 25.

[0029] 1) Rock drilling and blasting: shallow holes are used for ore dropping, and CYTJ45 hydraulic rock drilling rig is used for rock drilling. The blast hole diameter is φ42mm, the blast hole depth is 3.1m, and the equipment efficiency is 180 meters / shift. Emulsion and ammonium nitrate explosives are used as explosives, and digital detonators are used for detonation. Ventilation should be strengthened after blasting to expel blasting smoke as soon as possible.

[0030] 2) Prying: Prying is performed immediately after blasting and ventilation. If the stability of the roof 25 is poor, the roof 25 is anchored after prying.

[0031] 3) Mining: Due to the thin thickness of the ore body, cars cannot directly enter the mine to transport the ore. Therefore, the ore in the mine is transported to the ore centralized loading point 9 by a shovel loader and then directly loaded into the truck in the pit.

[0032] 4) Ventilation of the mining area: The middle transport tunnel is used for air intake. Fresh air flows through the inner ramp and segmented tunnel 1, and then flows to the mining working faces on both sides through the cutting uphill 2. The dirty air after washing the mining area flows through the mining area return air port 8 into the upper level segmented tunnel 1, and is discharged into the upper middle section horizontal tunnel through the inner ramp, and then discharged to the surface through the return air shaft. Local fans are arranged on the working face to assist ventilation.

[0033] 5) Empty area treatment (underground space utilization): After the mining of the ore room is completed, the area with poor stability of the roof 25 is filled with waste rock cementation using waste rock from the production period and waste rock after photoelectric ore dressing. Other areas with stable surrounding rock or good support are used as underground space. The mined-out area of ​​the mining field is constructed and utilized as a data center computer room, and the data center server 11 cabinets are installed in the underground space of the mining field.

[0034] The utilization method makes it possible for underground space in mines to no longer be treated as a potential disaster hazard, and fully and effectively utilize the underground space. The technical solution of the present invention has wide applicability and feasibility, and the utilization of underground space in mines is no longer limited to the utilization mode of traditional research. At the same time, after the mine stops mining, a new economic source is found for the closed mine.

[0035] This embodiment also provides installation steps for each data center server 11, specifically including: first fixing the bottom of each mounting frame 12 in a preset area, using fixing bolts 14 to fit the fixing plates 13 on both sides of the mounting frame 12 to the surface of the point column 7 closest to the side, and finally placing the data center server 11 on the surface of the bottom plate 20, and using the top plate 25 to fix one side of the data center server 11. Each data center server 11 is installed and supported by the outer mounting frame 12, thereby providing targeted locking and protection for each data center server 11, and directly blowing the heat dissipation airflow evenly from the surroundings of the data center server 11, thereby improving the efficiency and uniformity of heat dissipation.

[0036] In this process, the mounting frame 12 used is fixed to the ground of the space through the base 26 at the bottom, and a bottom plate 20 is provided at the bottom of the mounting frame 12, and a back plate 21 is integrally formed at the rear end of the bottom plate 20, and both sides of the back plate 21 are welded to the fixing plate 13 as a whole, and the fixing bolts 14 pass through the surface of the welding plate.

[0037] The external low-temperature airflow is transported to the interior of the air-cooling duct 15 through the air-cooling refrigeration system, and one side of the low-temperature airflow is transported to the cooling component 16 on the top of each mounting rack 12 through the air-cooling duct 15. The interior of the cooling component 16 transports part of the low-temperature airflow to the interior of the thermal interlayer 22 through the first air inlet box 17, and at the same time, part of the low-temperature airflow is blown downward toward the surface of the data center server 11 through each guide fan 19 at the bottom through the second air inlet box 18.

[0038] The air-cooling process uses a cooling component 16, which includes a first air intake box 17 and a second air intake box 18. The air-cooling duct 15 passes through the first air intake box 17 and the second air intake box 18 at the same time, and the guide fan 19 is installed at the bottom of the first air intake box 17. A gap is set between the top of the placed data center server 11 and the guide fan 19, and one side of the heat accumulation area of ​​the data center server 11 is against the surface of the back plate 21, and the heat is directly transferred to the heat dissipation fins 23 inside the heat dissipation interlayer, and the bottom of the heat dissipation interlayer is set to an open state.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
