摘 要:针对回采工作面的底板断层及断层活化引起的突水,在分析采场断层活化突水机理的基础上,建立了力学分析模型并对断层活化和突水灾害的产生进行了分析、研究,得到了判断断层活化的剪应力准则。对断层最短突水路径进行了分析,建立了断层最短突水路径计算模型,该模型对类似地质条件下开采具有较大的意义。Aiming at water inrush caused by floor fault and fault activation of stope working face,On the basis of analyzing the mechanism of water inrush induced by fault activation in stope,the mechanical analysis model was established,the generation of fault activation and water inrush disaster was analyzed and studied.The shear stress criterion for fault activation was obtained.The shortest water inrush path of the fault was analyzed,and the calculation model of the shortest water inrush path of fault was established,which is of great significance to mining under similar geological conditions.
