Research on Establishing the Indexes System of Controlling the Coal and Gas Outburst Accident

Coal and gas outburst accident aggravates with the increasing depth of coal mining, which amplifies geostress on coal seam, gas pressure and gas capacity. Studying on coal and gas outburst accident, this paper sets up the indexes system of controlling on the coal and gas outburst accident with consideration on technology factor, including basic technological work, reliability of relative system, prevention technology and concept, technological innovation, technic equipments, and management factor, including investment, management, institution configuration on governing gas, as two main elements.
