| 摘 要： | 发生于2006年9月11日的南京石膏矿特大突水灾害不仅改变了矿区及外围的地下水流场, 并引发了矿区地面沉降变形, 对地表附属物产生了一定的破坏作用, 造成了包括矿山关闭在内的巨大财产损失。南京石膏矿涉及典型的深部矿山地质工程问题, 影响地下开采稳定、矿山灾害和环境问题的主要因素是矿体及围岩的岩性结构及岩体结构构造, 特别是断裂构造及其影响带裂隙发育情况、富水性、导水率。围岩的岩溶强烈富水带的存在是矿坑突水的直接水源; 矿体的软岩特性、矿山开采扰动使采场周围的应力场重新分布、开采对断裂构造及裂隙带等结构体的活化作用都加剧了突水灾害的发生。

| Abstract: | The especially big water invasion event occurred on September 11,2006 in Nanjing gypsum mine.It changed the groundwater flow field of the mining area and surrounding influenced area,and resulted in ground settlement and ground fissures over the mining space and periphery zone,and led to surface structure destroyed such as road,houses,and workshops,and caused tremendous economic losing including mine closed up.The Nanjing gypsum mine is a typical underground deep mine with geological engineering issues.The main factors influencing the underground mining stability,mine hazard,and geo-environmental problems are rock mass properties and their structures,which are especially as faults,joints or fissures etc.,their sale,mechanics and spatial,and water abundance and conductivity.The intensive karst water abundance zones exist in the rock layer above the ore bed and in its south,which are the direct water invasion source.The soft rock(ore) properties,together with deep mining,mining disturbance to the original stress field surrounding the mining space,the deformation activation of the existing faults or joints or fissures,provides the water invasion hazard conditions. |
