Abstract
In view of the difficulty of gas control in the stratified mining face of the high gassy thick coal seam in Changcun Mine,which restricted the safe and efficient mining of the working face,according to the difference of gas emission from the upper and lower layered working faces and the actual mining situation of the working face,the comprehensive gas control measures for the upper and lower layered working faces were proposed.Through the analysis of the field application results,after the comprehensive gas control measures were taken,the gas concentration of the upper and lower layered working faces during the mining period was kept below 0.3％,no gas overrun accident occurred during the mining of the working face.关键词
