Coal mine underground water prevention and control early warning system

Abstract

The invention relates to the technical field of coal mine underground water prevention and control early warning, in particular to a coal mine underground water prevention and control early warning system. The system comprises a monitoring terminal, a control terminal, a main power supply terminal, a node detection end, a ground detection end and a ground buzzer alarm, wherein the control terminalcomprises a node power supply control end detection unit, a node power supply end detection unit, a temperature and humidity detection sensor detection unit, a water level detection sensor detectionunit, an image sensor detection unit, a water flow detection sensor detection unit, a water pressure sensor detection unit, a node control end detection unit, a node buzzer alarm detection unit and amain control data analysis unit; and the node detection end comprises a node power supply control end, a node power supply end, a temperature and humidity detection sensor, a water level detection sensor and an image sensor. According to the coal mine underground water prevention and control early warning system, the effects of high efficiency, comprehensiveness and effectiveness of coal mine underground water prevention and control early warning are achieved.

Description

technical field [0001] The invention relates to the technical field of underground water prevention and early warning in coal mines, in particular to an underground water prevention and early warning system for coal mines. Background technique [0002] With the continuous increase of coal mining, the mining layers are getting deeper and deeper, the hydrogeological conditions of coal mines are complicated, and major water inrush accidents in coal mines occur from time to time, causing huge losses and adverse consequences to miners' lives and national property. Social influence, groundwater has become an important factor that threatens coal mine safety production. In recent years, mine water inrush has been one of the main disasters affecting coal mine safety production. The real-time monitoring and effective management of the mine are particularly important. In the traditional monitoring method, the method of manual measurement and recording is used to grasp the change of the...

[0002] With the continuous increase of coal mining, the mining layers are getting deeper and deeper, the hydrogeological conditions of coal mines are complicated, and major water inrush accidents in coal mines occur from time to time, causing huge losses and adverse consequences to miners' lives and national property. Social influence, groundwater has become an important factor that threatens coal mine safety production. In recent years, mine water inrush has been one of the main disasters affecting coal mine safety production. The real-time monitoring and effective management of the mine are particularly important. In the traditional monitoring method, the method of manual measurement and recording is used to grasp the change of the water level (water pressure) for the hydrological observation holes above and below the mine; the measurement of the pipeline flow and open channel flow is also used The traditional monitoring method cannot monitor the required monitoring data in real time, and cannot realize dynamic monitoring and alarm functions, and the existing detection device cannot set nodes according to the depth of the mine Real-time monitoring of different positions of the mine, the precipitation at the mine mouth often affects the water level inside the mine, so the mine lacks a detection device for surface rainfall, which cannot play an early warning role
