Automatic mine drainage control system

Abstract

The invention discloses an automatic mine drainage control system. The system comprises a ground central control room and a plurality of pump rooms, wherein an upper computer is installed in the central control room and comprises two industrial personal computers, each pump room comprises a plurality of inner water sumps and a plurality of outer water sumps, water pumps, ultrasonic flowmeters, mining pressure sensors, negative pressure sensors and liquid level sensors are arranged in the outer water sumps and the inner water sumps, a monitoring stations are arranged in the pump rooms, the manual / automatic control function of one / the plurality of water pumps is achieved, and meanwhile the complete monitoring protection and alarm functions of the water level, the pressure, the flow, the temperature and the like are achieved. The system has the advantages that the system adopts a two-stage network topology structure; although double redundancy backup systems are adopted by a ground system, an underground and ground interruption emergency mechanism is still designed in the system, once the system breaks down, an underground-130 pump room No.1 master station automatically takes over and are responsible for control and analysis authority of the whole system, and it is guaranteed that the risk resistance of the whole system is high.

Description

technical field [0001] The invention relates to the technical field of mine safety monitoring, in particular to a mine automatic drainage control system. Background technique [0002] The formation of mine water is generally caused by the exposure of the roadway and the subsidence of the goaf to the water source. The water source is mainly atmospheric precipitation, surface water, fault water, aquifer water, goaf water and mining operation water. In the raw coal mining of coal in my country, an average of 2-4 billion cubic meters of groundwater will need to be pumped to the ground by drainage equipment every year. If the mine water cannot be discharged from the mine in time, it will not only restrict the mining of the mine, but also cause disastrous consequences such as casualties, equipment property loss, and mine collapse. [0003] The technology was poor in the early years. With the continuous progress of society, the drainage systems in many old mines have obvious failu...
