| Abstract: | Based on double longwall mining on confined aquifer in Yangzhuang colliery, the stress dis-tribution and fracture characteristics in floor strata are investigated by means of in-situ measurement, physical modeling and numerical analysis. The influence of different mining parameters on the mechanical behavior of floor strata is recognized. The rational technical parameters and engineering measures are proposed through the study for safe mining on confined aquifer. |
