浅谈底板岩巷掘进工作面的安全管理

煤矿安全一直以来都是煤矿的首要大事,高瓦斯突出矿井为了能够更好的治理煤层瓦斯,采用在煤层底板中施工专门（独立）的底板岩巷预抽煤层瓦斯,掩护上部煤巷掘进。因底板巷距B4煤层底板法向距约8～10m,底板岩巷的安全管理显得尤为突出,本文从控制底板岩巷层位、通风管理等七个方面论述了底板岩巷掘进工作面的安全管理,为相似矿井的安全生产提供技术借鉴。

Discussion on Safety Management of Floor Rock Drivage Face

Safety is always the principal thing for collieries.The particular floor rock roadway in coal seam floor is often applied to gas pre-drainage to shield the drivage at the upper roadway of collieries with gas outburst to control gas better.The safety management of floor rock roadway is prominent due to the normal distance of 8 to 10 meters between the floor lane and B4 coal seam floor.The paper elaborates the safety management of floor rock drivage face from seven aspects such as the control of the floor rock roadway layer and ventilation management etc.in Pinghu Colliery,which provides technological references for the safety production of similar collieries.
