Traditional contact based on the drilling of coal and gas outburst prediction method had great limitations. According to dynamic characteristics of gas emission, early gas outburst warning was of great significance to protect and improve the efficiency of coal mine safety in production. Based on Dashucun mine drivage face gas emission investigation and analysis of dynamic characteristics, ore prominent warning index adapting to the mine was determine, and with the aid of mine safety monitoring system and the local area network (LAN), builded the mine ore prominent warning system based on gas emission, implemented the coal mine tunneling faces highlight the real-time, dynamic early warning of danger. The successful application of early warning system with the traditional prediction method of contact formed complementary, effectively improved the accuracy of the outstanding risk to ensure the safety of mine production.
