F_(29)断层突水危险性研究

Study on water inrush risk of F_(29) fault

为了研究断层在煤矿开采过程中的突水危险性,以F29断层为例,通过对水头压力、断层落差与倾角、矿山压力等主要突水因素进行分析,并且进行FLAC3D断层突水通道形成过程数值模拟分析,得出了F29断层局部具有突水危险性的结论,对过断层的安全采掘具有指导意义。

In order to study water inrush risk of faults during exploitation in coal mine, the main water inrush factors of water pressure, fault fall and obliquity, and mine pressure were studied, taking F29 fault as an example. Furthermore, the simulation of FLAC3D was carried out by the mathematical model for the forming processes of water inrush channels. It drew the conclusion that F29 fault has partial water inrush risk. It is useful for the safe work passing faults in a mining zone.
