梧桐庄矿地热异常成因初探

简述了梧桐庄井田的地质、水文地质条件及井田热水特征。在此基础上,结合梧桐庄井田的水化学特点、地质构造特征、地下水径流条件,针对地热形成必须具备的“热水储层”、热储盖层、热的来源、导热通道”四大因素进行了分析,认为梧桐庄井田为一受活动性强大断裂控制的、深循环对流型的热水型地热异常区,为今后矿井治理与利用地热资源提供了依据。

Preliminary Research on Genesis of Geothermal Abnormalism in Wutongzhuang Mine

The geological and hydrogeological conditions of Wutongzhuang mine field and properties of thermal water in mine field have been brief reviewed. On the basis and combine with the hydrochemical properties and features of geological structure and watershed conditions of ground water of Wutongzhuang mine field, and carried out analyses aim at 4 factors needed by geothermal formation such as " reservoir of thermal water, thermal reservoir caprock, thermal source and passageway of heat conduction" , and hold that Wutongzhuang mine field is a hot water type geothermal abnormal area which controlled by faults of strong activity and belongs to convection type of deep cycle. So it hos provided bases of harness of mine and utilization of geothermal resources.
