Problems solved by technology
At present, the safety monitoring system installed by the production and operation units monitors the gas concentration, temperature, negative pressure, CO concentration, wind speed, smoke, temperature, damper switch, etc. in the coal mine workplace in real time. Explosion accidents such as dust explosions, pyrotechnic explosions, and gas and coal dust explosions cannot be monitored in real time. After an explosion accident in a coal mine, the accident report mainly relies on the telephone to report to each level. The reporting time is slow, which delays the first emergency rescue time of the explosion accident.

The invention relates to a coal mine safety monitoring system connected with explosion impact air-pressure explosion-protection sensors, and belongs to the technical field of coal mine monitoring. The coal mine safety monitoring system is characterized in that the explosion impact air-pressure explosion-protection sensors (2) are arranged on underground excavating working faces, main laneways andmain drilling chambers, and places possibly affected by an explosion, and are directly connected with a monitoring substation (13) of a current safety monitoring system (1) by special communication cables (3). The technical proposal ensures that the explosion information of a coal mine where an explosion accident occurs is transmitted to the safety monitoring systems of supervision departments atcounty, municipal and provincial levels at the very beginning, thereby gaining the time for rescue.
Description
technical field [0001] The invention relates to a coal mine safety monitoring system connected with an explosion-impact air pressure explosion-proof sensor, belonging to the technical field of coal mine monitoring. Background technique [0002] Article 13 of the "Measures for the Implementation of Safety Production Permits for Coal Mine Enterprises" stipulates that high gas, coal and gas outburst mines shall be equipped with gas drainage systems and safety monitoring systems according to regulations, and low gas mines shall be equipped with gas power-off devices and wind power gas blocking devices. At present, the safety monitoring system installed by the production and operation units monitors the gas concentration, temperature, negative pressure, CO concentration, wind speed, smoke, temperature, damper switch, etc. in the coal mine workplace in real time. Explosion accidents such as dust explosions, pyrotechnic explosions, and gas and coal dust explosions cannot be monitor...
