Mine confined water self-discharging system

Abstract

The invention discloses a mine confined water self-discharging system, which comprises a confined water supercharging device provided with water inlets (38 and 40) and water outlets (39 and 41) and an automatic reversing device, wherein a power output end of the automatic reversing device is connected with a power input end of the confined water supercharging device by water pipes (46 and 47), and a power output end of the confined water supercharging device is connected with a power input end of the automatic reversing device. The system has the advantages that: the design is reasonable, themanual control of the system is unnecessary after the starting, the confined water can be continuously discharged from the mine all year around, the operation of the system is safe and reliable, the labor power is saved, the fresh confined water can be automatically discharged to the ground, and directly used for industry and agriculture without any treatment, even used as domestic water, and thesystem can not only make full use of water source, but also avoid the environmental pollution; moreover, the system also has the advantages of simple structure, low cost, energy conservation, convenient maintenance, and strong safety, and can alleviate the labor intensity of workers and create good production benefits and social benefits for mine enterprises.

Description

technical field [0001] The invention belongs to underground drainage equipment for mining, in particular to a mine pressurized water self-drainage system. Background technique [0002] There are two different buried types of groundwater, phreatic water buried above the first stable aquitard and confined water buried between the upper and lower stable aquitards. As the mining depth of the mine continues to increase, when it reaches the position of the confined water, due to the influence of the hydrostatic pressure, the confined water will flow into the mine, causing a water inrush accident. The water level after the inrush is determined by the pressure of the confined water. Pressure decides. [0003] In coal mine production, water inrush is the second most serious accident after coal mine gas outburst. The hydrogeological and structural geological conditions in most mining areas in China are very complex, and about 65% of the mines are threatened by severe water inrush. ...

AI Technical Summary

Problems solved by technology

[0008] Limited by technical conditions, it is currently impossible to identify the precursory information of water inrush and then give an early warning; therefore, pre-drainage, decompression and decompression are still the main methods for mine water disaster prevention and control

At present, centrifugal pumps and submersible pumps are the main drainage equipment, but using pumps consumes a lot of electricity and costs a lot, and requires a special person on duty to manually start and stop the equipment, which is less safe
