摘　　要：该矿为一复式背斜构造,核心由中、上泥盆统和下石炭统火山岩构成,两侧为中、上石炭统白云岩,是矿区重要的控矿构造。矿区围岩侵蚀强度大、类型复杂,具有多期叠加、分带性明显等特征。根据矿床成矿条件、地层岩性、构造、物化探异常等综合因素分析,在矿区莲花山西南部146~143线、厂背斜核部、老厂水库一带、睡狮山、下平坝等区域具有很好储矿空间,具备找寻铅锌盲矿体的地质条件。The mine is a duplex anticline construction,it core is composed by middle Devonian,upper Devonian and lower Carboniferous volcanic rocks,the both sides of the mine are middle and upper Carboniferous dolomite,it is the important ore-controlling structure of the mine lot.The geotechnical erosion of the mine has high strength,the type is complex,it has multi-stage superposition and obvious zoning and the other characteristics.According to mineralization conditions of ore deposits,stratigraphic lithology,construction,geophysical and geochemical anomaly and the other comprehensive factor analysis results,the mine has good ore-contained space in 146~143 line of south-west part of Lianhuashan,arch core of Laoshan mine,reservoir area of Laoshan mine,Shuishishan,Xiapingba and so on,it has geological conditions for searching of lead-zinc blind ore bodies.
