Research and application of coal and gas outburst early warning system based on gas geological features

The geological structure of coal mines has always been a dangerous object attention in mine outburst prevention work. In order to realize safety information management and early warning gas disasters, comprehensive use theory, disaster computer technology other analysis methods, considering the influence structure, seam occurrence parameters, an indicator system for identifying risk outbursts reflecting characteristics constructed. identification is constructed using principle multi-index step-by-step extreme value determination, it applied on-site 3303 Measure Lane East Shaft Area Sihe Mine. research results show that can provide accurate area (belt) affected by 10m, based on signs geology such as thickness soft layers changes thickness. This provides effective support effectively prevent disasters ensure production safety.
