Abstract: In view of shortcomings that current monitoring of deep dynamic disaster in coal mine mainly depends on the on-line collector，which cannot realize data parallel and rapid sampling, a set of real-time and on-line monitoring system for mine dynamic disaster was designed. In the system, acoustic emission sensors, gas sensors and stress sensors are used to real-timely monitor parameters of strain energy, gas concentration and stress of coal and rock during occurrence of mine dynamic disaster; monitoring station is used to real-timely collect and process various sensor signals; PC data management software is used to realize effective analysis and results early warning of characteristic parameters change rule, so as to realize continuous dynamic monitoring of the dynamic disaster. Actual application results prove reliability of the system.
