| 摘 要： | 为了研究团柏煤矿煤层开采对底板岩层的破坏规律,制定相应的防底板突水方案,通过现场实测和数值模拟相结合的研究方法,分析煤层开采对底板破坏规律。结果表明:底板的破坏程度、破坏区域与含水层空间关系是决定矿井底板水害发生与否的关键因素,团柏煤矿10煤开采对底板的破坏范围为12 m~15 m,基于煤矿水文地质条件和研究成果提出了该煤层开采时底板突水隐患的预防和治理对策。研究结果对矿井开采设计与矿井防治水工作具有重要的指导意义。 |

| Abstract: | In order to study the damage rules of floor rock stratum result from coal mining,and formulate prevention water-inrush scheme,the actual measurement and numerical simulation on 10th coal of tuan-bai mine was used to analysis the laws.The results shows that,the key factor which restrict mine flood occurs was damage degree of floor and the spatial relationship of destroy regional and aquifer,the damage height of floor is about 12 meters to15 meters.floor water hazard preventing and controlling countermeasures... |
