Water-inrush mechanism in working face under the effect of multiple-factors coupling

摘要：

In order to analyze the water-inrush mechanism of 51101W working face in liang zhuang coal mine,from the aspect of water quantity,water quality,water temperature and so on,we judged water-inrush water source as Ordovician limestone water,established water-inrush analysis model of vertical path in crack concentrated belt,analyzed water-inrush paths and the affect factors,thought that water-inrush mechanism of the working face was rock-hydraulic phenomenon which happened under the coupling of geologic structure,high confined groundwater,mine pressure,multi-faults and large area hanging arch are the main reasons to water-inrush.The control achievement proved that this analysis is right.
