Abstract

Based on mining in working face floor karst collapse column, the damage of surrounding rock and the water inrush of GeTing coal floor of concealed karst collapse column as the research object, using numerical simulation software FLAC3D for mining stress field and plastic failure zones in the process of vertical direction and the vertical displacement change analysis, analyzed the different forward distance of concealed under the floor water inrush process of karst collapse column. The results show that the surging forward distance, increased the plastic range, the karst collapse column bottom vertical displacement increasing, when the coal floor of the plastic zone and the plastic zone of karst collapse column connection .
