| Coal and gas outburst,which threatens coal mine safety production,is a kind ofcomplicated dynamical phenomena in minings and one of the most serious naturaldisasters.Regional predictionis based on the cognition of mechanism of coal and gas outburst.On account of complexity of outburst,different viewpoints are in concurrence.At present,it is widely accepted in the world that Coal and gas outburst is the synthesized result of stress,gas, coal physics mechanics etc. It is indicated by domestic and overseas mining practice thatcoal and gas outburst is regional distribution and the disaster occurrence area accounts foronly 8%～20% of whole mine district. In this paper, geo-dynamic zoning method was used toascertain regional geology structure, geo-stress survey and numerical simulation were used tomake sure rock mass stress state, the influence between gas stress and content and othersfactors affecting coal and gas outburst was analyzed. Based on which, multi-factor probabilityprediction method was applied to predict regional coal and gas outburst danger. The miningarea was then divided into coal and gas outburst dangerous area,threat area and safety area.By assessing and predicting the danger of coal and gas outburst, the accuracy of gas of coaland gas outburst predict was improved.
