In connection with the coal and gas outburst problem in coal seam of Yian coal mine in recent years, comprehensively counted and analyzed the forecasting index of heading face outburst namely drilling cuttings volume index S,drilling gas inrush initial velocity q and gas desorption index of drill cuttings Δh2 .Using the ideas of the mathematical model,and combined with standard deviation and fuzzy priority sorting decision,makes sure the out-burst prediction sensitive indexes is q and Δh2 of heading face in coal seam of Yian coal mine.This conclusion can guide prevention outburst in the mine,is of great significance and far -reaching influence.
