Coal mine safety monitoring system connected with explosion impact air-pressure explosion-protection sensors

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 and main 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 at county, municipal and provincial levels at the very beginning, thereby gaining the time for rescue.
