23112主采面重点瓦斯地区通风及瓦斯治理研究
|
摘要
为解决山西曙光船窝煤业23112工作面回采初期工作面风量不足、瓦斯浓度过高、下隅角出现瓦斯积聚状况,该矿通过采用了单进双回、双进双回等通风方式,改进割煤工艺,有效控制了23112工作面的瓦斯浓度,确保了工作面的高产高效安全开采。
In order to solve such problems in 23112 working face of Shanxi Shuguang Chuanwo Coal Industry as the insufficient air volume, the too high gas concentration, the corner gas accumulation conditions etc, the mine adopted the single advance-and-double-return, double-advance-and-double-return ventilation way, and improved the coal cutting process, which effectively controlled the 23112 working face gas concentration, ensured the safety of the high production and efficiency of working face mining.
