Coal mine water quality quick detection and water damage pre-warning system

Abstract

The invention relates to a coal mine water quality quick detection and water damage pre-warning system. The system is characterized in that a sensor set, an ion electrode socket, a handle and a secondary instrument are included; the sensor set is used for collecting ion and gas simulation signals contained in water at detection points; each sensor in the sensor set is fixedly arranged at one end of the ion electrode socket; the other end of the ion electrode socket is fixedly connected with the handle, and a transmitter is arranged in the handle; the transmitter converts the detected simulation signals collected by the sensor set into digital signals and sends the digital signals to the secondary instrument; the secondary instrument carries out water quality analysis and water source judgment according to the received signals and conducts out water damage pre-warning. By means of the system, serious water damage accidents of a coal mine can be greatly reduced, safety of coal mine production is improved, and coal mine casualties are reduced.

Description

technical field [0001] The invention relates to the technical field of coal mine detection and early warning, in particular to a coal mine water quality rapid detection and water damage early warning system. Background technique [0002] my country is one of the countries with the most serious coal mine disasters in the world. In recent years, although the state has adopted corresponding management measures to reduce the annual death toll of coal mines slightly, the annual death toll caused by coal mine floods is still rising. Water, alluvial flooding and surface water inflows occur frequently. In recent years, various frequent mine disasters and coal mine flooding are caused by these four kinds of water hazards. Therefore, the early warning of coal mine water hazards is of great significance to reduce or even eliminate vicious mine disasters. [0003] There are three reasons for frequent major disasters caused by water seepage in old empty areas: 1. Old empty areas are co...

Problems solved by technology

The previous research work was limited to the identification of mine water inrush sources, but this method needs to take out the underground water samples and send them to a special laboratory for testing. The speed is slow and the cycle is long. It is difficult to solve urgent problems in production and fail to achieve the purpose of early warning. Sudden mine water hazards such as Laokong seepage cannot be eliminated, especially when the precursors of Laokong seepage such as weak seepage in coal and rock walls, subsidence column inrush, and alluvium burst water are too small to be sampled and tested. It also missed the precious opportunity to identify water sources, making disasters that could have been avoided become helpless
