琅琊山铜矿地下开采空间开发利用前景分析

琅琊山铜矿位于安徽省滁州市城区,与琅琊山风景区附近,地理位置优越。该矿山矿床为矽卡岩接触交代型富铜矿床,矿体顶板及围岩以石英闪长玢岩为主,局部为寒武系碳酸盐岩;围岩工程力学性质及稳定性良好,地下水贫乏;地下采矿遗留有大面积的开采空间。通过对琅琊山铜矿赋存的自然背景条件、地下采矿方式、地下遗留的开采区面积来分析该矿山地下开采空间可开发利用前景,提出了未来可供选择的利用方式为建设矿山公园、人防工程、地下物资储备库等,以此变废为宝,提升地下采矿的社会经济效益。

Analysis on the prospect of underground mining space exploitationat Langyashan copper mine

Langyashan copper mine has an excellent location in the vicinity of Chuzhou City and Langyashan Scenic Area. The deposits is Skarn contact meta - type copper - rich deposits on which top and every side rock are mainly quartz-porphyrite rock and the Cambrian carbonate rock in the local, with good mechanical properties and stability,and groundwater scarcity, in where a large area of mining space appearing after mining. Based on the natural background conditions, the methods of underground mining. area of underground goaf space, the prospect of development andutilization of the goaf space was analysed and researched by presenting of the available ways on construction of mine park, civil air defense project, underground storage, hazardous waste disposal sites and so on, in where the precious space appearing, which mining benefits being improved further.
