摘　　要：为了解决阳泉矿区在开采过程中本煤层瓦斯涌出量大,上隅角瓦斯经常超限的问题,通过对工作面前方煤壁的应力变化情况和卸压瓦斯在煤层中的运移和涌出规律及其之间关系的研究,为本煤层抽采瓦斯正确选择抽采瓦斯钻孔参数、提高瓦斯抽采率、钻孔位置的选择提供了依据。Order to solve the high gas emission from the mining seam and the gas content frequently over limit at the top corner during the coal mining process in Yangquan Mining Area,the study on the stress variation of the coal wall at the front of the coal mining face and the pressure released gas in seam migration and the gas emission law as well as the relationship could provide the references to correctly select the gas drainage borehole parameters of the mining seam gas drainage,to improve the gas drainage rate and to select the borehole location.
