摘　　要：随着社会生产生活对煤炭资源需求度与日俱增,致使煤矿开采深度不断增加,矿井作业施工难度增加,煤层透气性下降,瓦斯浓度和压力等参数逐步升高,很容易出现瓦斯积聚或超限等问题,严重情况下会导致爆炸事故,危害到作业人员的人身安全。对此,需要充分契合煤与瓦斯突出矿井特性,在工作面回采中加强瓦斯治理,优化通风系统,改善井下作业环境,保障井下作业效率和安全。本文此展开分析,契合煤与瓦斯突出矿井实际寻求合理的瓦斯治理方法,合理应用到采煤工作面回采中。With the increasing demand for coal resources in social production and life,the depth of coal mining is increasing,at the same time,the construction difficulty of mine operation is increasing,the permeability of coal seam is decreasing,and the parameters such as gas concentration and pressure are gradually increasing,which leads to problems such as gas accumulation or overrun.In severe cases,it will lead to explosion accidents and endanger the personal safety of operators.Therefore,it is necessary to fully meet the characteristics of coal and gas outburst mines,strengthen gas control in the recovery of mining face,optimize ventilation system,improve underground working environment and ensure the efficiency and safety of underground work.Combined with the actual situation of coal and gas outburst mines,this paper analyzes the problem and seeks for a reasonable gas control method,and applied it into the recovery of mining face reasonably.
