摘　　要：随着煤矿开采深度的增加,瓦斯涌出量大幅度提高,而采空区中由于落煤、邻近层、围岩等因素导致的瓦斯涌出,在矿井瓦斯涌出量中所占比例不容忽视,单靠通风方式的改变很难满足矿井安全生产的需求。本文以郭庄矿为例,分析总结了几种采空区抽采方法在3313工作面的应用效果,有利于后续抽采的优化设计,并为其他采场和邻近矿井的瓦斯抽采提供借鉴。With the increasing of mining depth,gas emission increased greatly,and because of the coal in goaf,adjacent layer and surrounding rock caused by factors such as gas emission,the proportion in the mine gas emission cannot be ignored.It is difficult to meet the demand of mine safety production by means of ventilation.Based on Guozhuang Mine,this paper analyzed the application effects of several goaf extraction method in 3313 working face,and summarized several goaf extraction methods,which is advantageous to the subsequent extraction optimization design,and provides good reference for other mine stope and nearby gas extraction.
