Analysis is made on the influences of the main constructions in the mine on the roof wall rock and the water containing layer, the ubiety between the roof and the interlayer or relative interlayer, the influence of the water containing layer and exploration drilling on jamb mining. The safety mining depth as well as the height of collapsed belt and the cranny guiding water are calculated. Furthermore, the ANSYS software is adopted to simulate the stability of the cover terrane and the maximum permit exposure area.
