煤层底板突水是涉及地质学、煤矿开采学、岩体水力学和岩石断裂力学等学科的一个复杂问题。

It is a complicated problem involving several of subjects such as geology, coal mining, rock hydraulics and rock crack mechanics.

在底板高压岩溶含水层上且靠近较大断裂构造弱面采矿时，隔水层段的残余厚度和断裂的采动活化程度是能否突水的关键因素。

The residual thicknesses of aquifuge and mining reactivations of the fault are the key factors to control the water inrush when mining is near the large-scale fault with karst aquifer under the floor.
