摘要
近年来针对邯邢矿区的一些突水事故,对底板奥灰突水特征进行了系统分析。结合突水实例,对大采深高承压水矿井底板奥灰突水致灾关键因素进行了深入剖析,系统地阐述了深部煤层开采底板奥灰水防治所面临的难题,针对性地提出了地面奥灰区域超前治理的防治水对策,变一面一治理为一个采区或一个水平进行治理;将治理目标层由薄层灰岩变为奥灰含水层顶部;变采前治理为掘前治理,目的在于从突水根源上消除奥灰岩顶部存在的地质缺陷,达到深部矿井安全开采的防治水目的,对大采深高承压水矿井防治奥灰水害具有重要的指导意义。
Aiming at some water inrush accidents happened in Handan-Xingtai mine district in recent years,the features of water inrush from the Ordovician limestone of the floor were systematically analyzed.Combining with the example of water inrush,the disaster causing key factors of water inrush from the Ordovician limestone of the floor for the coal mine with deep mining depth and high pressure water were deeply analyzed,and its prevention difficulties were systematically elaborated,the targeted countermeasures of water inrush prevention that were advanced treatment of surface Ordovician area were proposed,which changed the treatment of one face to the treatment of one mining district or one level.The treatment targeted layer was changed from thin limestone to the top of aquifer in Ordovician limestone.The treatment was changed from ahead of mining to ahead of advancing in order to eliminate the geological faults of top of Ordovician limestone from the source of water inrush and ensure the safety mining,which had a directing significance for the coal mine with deep mining depth and high pressure water.
