Comprehensive Analysis of Geological Structure Physical Environment Impact on Coal and Gas Outburst

Through a comprehensive discussion upon the tectonic coal characters,tectonic stress characters,coal seam gas occurrence laws in geological structural belt and tectonic combination characters,this paper analyzes the effects of geologic structure physical environment on the coal and gas outburst.It shows that the existence of tectonic coal stratification provides a favorable condition for the initial excitation and further development of the coal and gas outburst,besides,the complex degree of geological structure damage,the coal seam gas occurrence in the geological structural belt,the superposition of the tectonic stress field and the growth of tectonic coal are the key factors influencing the outburst,which improves the risks of outburst.In addition,this paper hold the view that the comprehensive function of disturbing factors,such as the tectonic physical environment and mining activities,control the coal and gas outburst in the geological structural belt.
