大社矿井下开采对水体拦水坝的破坏机理及治理措施

Failure mechanism and control measures of water dam caused by underground mining in Dashe mine

通过分析开采引起的各种移动变形,对水体拦水坝的破坏机理进行了分析,结合各水体拦水坝的结构特点和所承受的开采变形情况,提出了针对性的井上下治理措施。其中,西佛店、大淑村、南旺和香山圆水体需在开采过程中对拦水坝裂缝进行治理;矸石山水体和香山水体需要在开采前对拦水坝进行工程治理,在开采过程中对坝体裂缝进行治理。

By analyzing the mechanism of water dam failure caused by mining movement and deformation,combining with the structural characteristics and deformation of each water dam caused by mining, surface and underground control measures are proposed. For the Xifodian,Dashucun,Nanwang and Xiangshanyuan water body,dam crack should be treated in the mining process; and for Ganshishan and Xiangshan water body,engineering control measures should be taken before the mining process and the cracks be treated in the mining process.
