摘要
通过对山西省阳泉矿区五矿的地质背景分析,结合已完钻孔成果及野外踏勘资料,对五矿区内地层特征进行了阐述,着重对奥陶系中统分组情况及岩性进行总结,并概述了该区构造特征及地下水补、径、排条件,对该区陷落柱在平面、剖面及陷落深度、物质组成等方面发育特征进行初步阐述和总结,概括分布规律,分析岩溶陷落柱形成机理,建议阳煤五矿加强陷落柱的调查研究和探测预报工作。
Through the No.5 coalmine geological setting analysis, combined with drilling results and field reconnaissance information expounded strata characteristics in the coalmine, emphasized on formation dividing and lithologic characters of Middle Ordovician Series, generalized structural features and groundwater recharge, runoff and discharge conditions. Preliminary summarized development characteristics of subsided column＇s planar, section configurations, subsiding depth, material composition and distribution pattern, analyzed subsided column formation mechanism and advised No.5 coalmine to strengthen subsided column investigation and orediction.
