摘要
Abstract
Taking the current coal seam of Hexi Coal Mine as the engineering background,by analyzing the occurrence law of coal seam gas,the main controlling factors affecting the coal seam gas content are obtained.The contour map of coal seam gas content is drawn,and the gas emission rate of 3# and 4# coal seams is predicted using the source separation prediction method.The results indicate that the burial depth of the coal seams is the main controlling factor for the occurrence of gas,satisfying a linear relationship:3# coal seam is W3#=0.084 2H-31.898,R2=0.833 2;4# coal seam is W4#=0.034 2H-5.97,R2=0.893 9.In the case where the production capacity of 3# coal seam is 1.4 Mt/a and the production capacity of 4# coal seam is 1.4 Mt/a,the absolute gas emission rate(Q)and burial depth(H)of the coal mining face in 3# and 4#coal seams follow a linear regression relationship of Q3#=0.270 1H-94.36,Q4#=0.062 8H-14.42.The predicted results can provide important data basis for coal mine gas prevention and control.关键词
