Deep-well mine auxiliary drainage device utilizing surface water potential energy

Abstract

The invention discloses a deep-well mine auxiliary drainage device utilizing surface water potential energy. The deep-well mine auxiliary drainage device comprises five parts of a box, piston connecting rods, a gear transmission system, valves and pipelines; the box is internally provided with two purified water cylinders and two sewage cylinders; the device is mounted at the bottoms of main and auxiliary wells of a mine, during starting, surface water is injected into the purified water cylinders through the pipelines, the piston connecting rods are hydraulically driven to move downwards, pistons in the sewage cylinders move upwards through gear transmission, and sewage is lifted; the purified water cylinders and the sewage cylinders each have a water feeding stroke and a water draining stroke, at the same time, the two purified water cylinders always conduct the water feeding stroke and the water draining stroke at the same time, the two sewage cylinders always internally conduct thewater feeding stroke and the water draining stroke, thus the water continuously enters the device, and the sewage is lifted; and the water feeding and draining pipelines of the purified water cylinders and the sewage cylinders are switched through the valves, and the valves control the tail ends of the connecting rods to be tightly attached to cams on gears to achieve linkage. The high-potential-energy water, from the surface, in a deep well mining water supply system serves as a power source for lifting the sewage downhole, the purposes of energy saving and cost lowering of deep well miningare achieved, and the water quality of the downhole water is not affected.

Description

technical field [0001] The invention belongs to the field of deep mine drainage and energy saving, and in particular relates to an auxiliary drainage device for deep mines utilizing potential energy of surface water. The device is suitable for drainage of deeply buried underground coal mines and non-coal mines. Background technique [0002] With the exhaustion of shallow resources, more and more mines are going deep. When deep mines are mined, they not only face the problem of "three highs and one disturbance", but also the rapid increase of drainage costs with the depth of deep mines. All of these restrict the increase of mining depth and the utilization and recovery of resources. Therefore, it is particularly important for deep well mining to develop energy-saving and cost-reducing mining technologies and reduce drainage costs. [0003] As we all know, when mining, on the one hand, it is necessary to use clean tap water on the surface for underground rock drilling, ore ...

AI Technical Summary

Problems solved by technology

[0004] At present, the status quo faced by deep well mines is that a large amount of high potential energy supplied from the surface to the underground has not been utilized, and a large amount of energy is required to discharge the wastewater from the deep well. How to reasonably and economically reduce the high water pressure of the surface water supply in deep well mining and Draining underground water to achieve energy saving, cost reduction and efficiency increase is an important issue that mines care about
