System for forecasting mine water regime and intelligently controlling drainage

Abstract

The invention relates to a system for monitoring and forecasting mine underground water regime and intelligently controlling drainage and belongs to the technical field of management of the mine underground water regime. The hardware devices of the system comprise an underground local accumulated water well accumulated water volume detection sensor group, a main accumulated water well accumulatedwater volume detection sensor, an RS-485 communication network module, a liquid level detection device, a master control room computer, an underground drainage pumping station and a pumping station master control box, wherein the RS-485 communication network module comprises an RS-485 communication control bus, a bus communication controller and a repeater. The system has the advantages of savingenergy, reducing emission, reducing underground drainage cost, improving the safety of underground drainage, increasing the communication distance of an underground sensor, greatly reducing water level detection cost and improving system reliability. By the system, the underground water regime can be comprehensively known and controlled conveniently by a ground master-control room, and the safetyof the underground water regime is improved.

Description

technical field [0001] The invention belongs to the technical field of underground water regime management in mines, in particular to a mine water regime prediction and drainage intelligent control system. Background technique [0002] In the process of coal mine production, groundwater can often be seen flowing into roadways and working faces, which is mine water. The formation of mine water is generally caused by roadway exposure and goaf subsidence affecting water sources, and its water sources are mainly atmospheric precipitation, surface water, fault water, aquifer water and goaf water. [0003] Although the geological and hydrogeological mining conditions of each coal mining area are different, the formation process of mine water will be correspondingly different, but its mechanism and restrictive factors have common characteristics. Mine water presents two storage forms, that is, form 1, in order to ensure safe coal production, in the process of mining, it must be dr...

AI Technical Summary

Problems solved by technology

Existing liquid level detection sensors are relatively expensive, and it is impossible to establish a water level detection system

However, due to the relatively large randomness of water regime changes, it is impossible to establish an accurate mathematical model, so it is also impossible to predict the changes in the water regime.
