摘　　要：安徽省巢湖市望湖山水泥配料用砂页岩矿,为一单斜沉积层状矿床,主要赋矿层位为志留系坟头组、茅山组。为探讨该矿山的开发利用条件,详细分析了该矿床的地质特征、矿体特征。研究表明①矿区主要含矿层位坟头组(S2f)细砂岩、粉砂质泥岩;②矿石自然类型为泥质粉砂岩、粉砂质泥岩、细砂岩、粉砂岩;③矿床开采技术条件属以工程地质条件为主的中等类型(Ⅱ-2);在上述分析的基础上,进行了矿床开发利用初步分析,建议适当降低矿体工业指标,可实现资源集约化利用、扩大矿区资源储量,为后期详查、矿山建设及类似矿区地质找矿和开发利用提供借鉴。The wanghushan sand shale ore for cement proportioning in Chaohu City,Anhui Province,is a monoclinic sedimentary stratiform deposit,and the main ore bearing strata are the Fentou formation and Maoshan formation of Silurian system.In order to discuss the development and utilization conditions of the mine,the geological characteristics and ore body characteristics of the deposit are analyzed in detail.The results show that:①the main ore bearing strata in the mining area are fine sandstone and silty mudstone in the Fentou formation(S2f);②the natural types of the ore are argillaceous siltstone,silty mudstone,fine sandstone and siltstone;③the mining technical conditions of the deposit belong to the medium type(Ⅱ-2)mainly based on the engineering geological conditions;On the basis of the analysis,the preliminary analysis of the development and utilization of the deposit is carried out.It is suggested that the industrial index of the ore body should be properly reduced,which can realize the intensive utilization of resources and expand the resource reserves of the mining area,and provide reference for the later detailed investigation,mine construction and geological prospecting and development of similar mining areas.
