Online monitoring and pre-alarming system for surrounding rock pressure of coal mine tunneling roadway

MENG Qingyong;CCTEG China Coal Research Institute;  
For problems of difficult realization of effective monitoring and poor pre-alarming ability of existing surrounding rock pressure monitoring technologies for coal mine tunneling roadway, a kind of online monitoring and pre-alarming system for surrounding rock pressure of coal mine tunneling roadway was designed by use of wireless sensor technology, and structure, principle, data transmission mode, functional module and pre-alarming flow of the system were introduced in details. The application shows that the system achieves real-time monitoring of roof separation, stress and acoustic emission of tunneling roadway, and the comprehensive pre-alarming flow with multiparameter improves pre-alarming.
