目前,国内煤矿井下都基本采用防水闸门硐室和水闸墙为井下防水的主要安全设施,在井下巷道适当地点安装防水闸门硐室和水闸墙的位置,使矿井形成分翼、分水平或分采区隔离开采。在水患发生时,能够使矿井分区隔离,缩小灾情影响范围,控制水势危害,确保矿井安全。 At present, the domestic coal mine basically adopts the waterproof gate chamber and the water gate wall as the main safety facilities for underground waterproofing, and installs the positions of the waterproof gate chamber and the water gate wall in the proper place of the underground tunnel to make the mine form a wing, sub-level or sub-level District isolated mining. In the event of flooding, the mine can be partitioned to reduce the scope of the disaster, control water potential hazards and ensure mine safety.
