Qualitative and Quantitative Relationship of Coal and Gas Outburst Scale and Influence Factors

To improve accuracy of prediction of coal and gas outburst scale,the author based on Linhua Coal Mine representative 21 outburst accident data.Using method of combining qualitative and quantitative to analysis of the relationship between outburst scale and influence factors of coal and gas outburst and the close degree between factors and outburst scale.Studies have shown that Lin Hua-mine the main factor to influence and control the outburst scale followed by buried depthdegree of destruction of coalmode of operation= prominent forecast geological structure,provide a new way to forecast the outburst scale.
