Description

Technical Field

[0001] The utility model relates to the technical field of underground inclined shaft sludge discharge, in particular to a combined structure for drainage, sludge discharge and fine ore recovery at the bottom of an inclined shaft. Background Technique

[0002] When using an inclined shaft to hoist ore in an underground mine, there will always be some crushed ore or ore powder mixed with a part of slurry or muddy water, which will inevitably be scattered in the inclined shaft during the ore discharging process. Therefore, after ore discharging for a period of time, a certain amount of fine ore and slurry water will accumulate in the inclined shaft. If not cleaned, on the one hand, it will cause waste of fine ore, and on the other hand, the slurry water will cause underground pollution, and over time, it will cause a safety hazard of the inclined shaft being flooded.

[0003] Generally, for the treatment of fine ore and slurry water in an inclined shaft, methods such as manual cleaning of fine ore slurry and water pump drainage, or cleaning with an electric scraper, a loader, a mucking machine and water pump drainage, or single air pressure tank sludge discharge, and jet pump sludge cleaning and water pump drainage are usually adopted. Traditional methods either have a simple method but are difficult and inefficient for manual cleaning, or have a high degree of mechanization but a large investment, are restricted by site conditions and are not conducive to large-scale mechanized operations, and the interference between the processes of cleaning fine ore, slurry and drainage is large, and the ideal effect cannot be achieved, bringing many adverse factors to subsequent production. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the defect that the existing manual and mechanical operations cannot achieve the ideal effect and bring many adverse factors to subsequent production, and provide a combined structure for drainage, sludge discharge and fine ore recovery at the bottom of an inclined shaft.

[0005] The technical solution adopted by the utility model to solve its technical problem is a combined structure for drainage, sludge discharge and fine ore recovery at the bottom of an inclined shaft, including an inclined shaft. There are ore bins and fine ore treatment chambers on both sides of the inclined shaft, and there is a fine ore trolley in the inclined shaft. There is fine ore and slurry water in the ore bin. A water channel, a fine ore sedimentation tank, a slurry sedimentation tank and a bottom water sump are arranged in the inclined shaft. The fine ore sedimentation tank, the slurry sedimentation tank and the bottom water sump are located at the bottom of the inclined shaft from right to left in sequence. The water channel is communicated with the fine ore sedimentation tank. The fine ore treatment chamber is arranged on the side of the fine ore sedimentation tank, and there is a roadway repair machine in the fine ore treatment chamber.

[0006] The fine ore and slurry water flow into the fine ore sedimentation tank through the water channel for primary sedimentation, the slurry water flows horizontally into the slurry sedimentation tank through the water channel for secondary sedimentation, and the slurry water flows horizontally into the bottom water sump through the water channel for tertiary sedimentation.

[0007] The roadway repair machine is equipped with a bucket which shovels powdered ore into the powdered ore trolley and transports it out of the inclined shaft. A sludge discharge tank and a sludge delivery pipe for transporting sludge to the outside are arranged in the sludge sedimentation tank. A water diversion device and a water diversion pipe for transporting water to the outside are arranged in the bottom sump.

[0008] Further, the powdered ore and sludge water in the ore bin flow into the powdered ore sedimentation tank through the water channel and undergo primary sedimentation in the powdered ore sedimentation tank. The powdered ore precipitates preferentially and is transferred to the powdered ore trolley by the bucket, and is lifted to the upper middle section ore bin or the ground by the powdered ore trolley for recovery.

[0009] Further, when the sludge water in the powdered ore sedimentation tank is full, it overflows and flows horizontally to the sludge sedimentation tank for secondary sedimentation. There is also a sealed mud bin chamber on the side of the inclined shaft. A steel sealed mud bin connected to the sludge delivery pipe is installed in the sealed mud bin chamber. The steel sealed mud bin is provided with a mud discharge pipe. The sludge is transported to the sludge delivery pipe, the steel sealed mud bin, and the mud discharge pipe in sequence through the sludge discharge tank, and the mud discharge pipe transports the sludge to the goaf or the ground.

[0010] Further, the steel sealed mud bin is also provided with a slag discharge pipe which is connected to a pipeline to discharge the remaining water and residues.

[0011] Further, the excess water in the sludge sedimentation tank flows horizontally into the bottom sump for tertiary sedimentation. There is also a pump chamber on the side of the inclined shaft. A pump is installed in the pump chamber. The pump is provided with a drain pipe. The water is transported to the drain pipe, the pump, and the drain pipe in sequence through the water diversion device, and the drain pipe discharges the water to the upper middle section sump or the ground.

[0012] Further, the connecting water channels of the powdered ore sedimentation tank, the sludge sedimentation tank, and the bottom sump adopt a roadway horizontal flow structure.

[0013] The utility model has the following beneficial technical effects:

[0014] The powdered ore is shoveled into the powdered ore trolley by the roadway repair machine and directly lifted to the upper middle section ore bin or the ground; the sludge is discharged to the stope for backfilling or directly to the ground through the sludge discharge tank via the steel sealed mud bin; the water is discharged to the upper middle section sump or directly to the surface through the pump. The utility model solves the problems of comprehensive utilization and discharge of powdered ore and sludge water generated during ore discharging from the ore bin in the inclined shaft. This construction process is simple, the process flow is clear and practical, the investment is small, the use is wide, and the effect is good. Description of the Drawings
