摘要
针对寺河煤矿东井区23071巷和33112巷连采机掘进工作面的瓦斯涌出规律，采用分源法进行了研究。结果表明，掘进面瓦斯涌出量随着掘进进尺的增加而增大，煤壁瓦斯涌出所占工作面瓦斯涌出的比例也是逐渐增加的。从统计数据可知，连采机掘进工作面的瓦斯涌出总量中，落煤瓦斯涌出占16．2％-34．5％，煤壁瓦斯涌出占65．5％-83．8％，为西井区和东井区接替盘区巷道掘进时的瓦斯治理提供了理论依据。
Gas emission law of 23071 lane and 33112 lane in Eastern Region of Sihe Coal Mine, was studied by using the subsource method. The results showed that gas emission was increasing because driving forward, and coal wall＇s gas emission ratio at coal face was gradually increased. Statistical data showed gas emission of failed coal occupied 16.2%-34.5% and gas emission of coal wall occupied 65.5%-83.8%. It provided a theoretical basis for predicting gas emission in the west and east region.
