摘要
华北型煤矿由于特殊的水文地质条件,主要受底板灰岩突水威胁,断层是灰岩突水最重要的突水通道之一。以断层的水文地质特征为主综合考虑突水时空与动态特征,进行底板断层突水水文地质分类,通过统计典型华北型煤矿断层突水实例,进行验证分析。研究成果可以为华北型煤矿底板灰岩突水防治提供借鉴。
Due to special hydro-geological condition,North China-type mines are mainly threatened by water inrush of limestone aquifer of floor.Fault is one of main channels of water inrush.Based on the hydro-geological features of the fault,time-space and dynamic features of water inrush are integrated to classify the hydro-geology of the floor fault.Typical fault water inrush accidents were calculated and verified in North China-type mines.The results could provide guidance to prevent the water inrush of limestone aquifer.
