| 摘 要： | 晋城成庄煤矿岩溶陷落柱比较发育,其中导水性陷落柱严重威胁着煤矿安全生产.结合三维地震勘探、矿井水文地质等资料,在分析成庄煤矿地层沉积史、区域构造演化史的基础上,研究了晋城成庄煤矿岩溶陷落柱的成因,认为陷落柱的形成是由奥陶系灰岩含水层的强径流溶蚀作用、地层旋回差异升降运动引起的.对于裂隙发育的陷落柱,陷落裂隙可能沟通强含水地层、地表水或采空区积水时,矿井开采过程易引起突水事故.

| Abstract: | Karst subsided columns greatly develope in Chengzhuang colliery,and some transmissibility subsided columns would badly threaten mining safety.By studying strata sedimentation history,regional tectonic evolvement history,three-dimensional exploration data and hydrologic geology data etc,it has been brought forward that subsided columns formation is attributed to both dissolution and erosion of Ordovician water to lime rock and the differential uplifting-subsidence of strata in different structure stages.The subsided columns,which have crevices extending to the strata containing water,surface water and accumulating water gobs,have stronger transmissibility and easily give birth to water outburst accidents. |
