Abstract：The traditional contact prediction method based on drilling for coal and gas outburst has a great limitation. The early warning of coal and gas outburst according to the dynamic characteristics of gas emission is of great significance for ensuring safe production and improving production efficiency of the mine. Based on the investigation and analysis on the dynamic characteristics of gas emission in the heading face in Dashucun Mine, the early warning indicators applicable for coal and gas outburst in this mine were determined, an early warning system based on the dynamic characteristics of gas emission of the mine was established with the aid of the mine safety monitoring system and LAN, and the real-time and dynamic early warning of outburst hazard in the heading face was thus realized. The successful application of this early warning system formed a mutual complement with the traditional contact prediction method, which improved the prediction accuracy of coal and gas outburst and ensured the safe production of the mine.
