Abstract
In order to carry on the effect-test of regional outburst prevention measures on the 12011 coal face of Xinyi coal mine.Accoding to the complex conditions of coal seam occurrence on the face and the provision of coal and gas outburst prevention,the effect-test holes are selected.The number of effect-test holes is analyzed by the 3σ rule.The boreholes index method and the gas remainder quantity method and outburst omen were applied to the effect-test of the regional measures,which finally determined the effect of outburst elimination.关键词
