| Abstract: | The water hazard was deduced as the cause of water cell breaking wllich was caused by over burden strata separation during mining activities according to hydrogeological and geotechnical analyses, physical analogue and numerical simulation. Drilling and borehole scanning verified the above results. To control the water hazards, the responding draining measure was taken and the tests were successful. The achievements were applied to the working faces with the similar hydrogeological condition to guarantee mining safe. |
