摘要

塘坝金矿区位于甘肃省武都县,属琵琶乡管辖,气候为温暖带大陆性季风湿润气候,区内水系发育,属长江流域嘉陵江水系。塘坝金矿床是赋存在坚硬、半坚硬的碳酸盐岩和碎屑岩层中,灰岩和硅质角砾岩等硬性岩石一般为完整-较完整,岩体结构类型为块状结构,岩石稳定,工程地质条件较好,千枚岩等软弱岩石和断裂影响范围内的岩石一般稳定性差,岩石较破碎,岩体结构类型主要为层状碎裂结构和散体结构。矿区工程地质勘探属于第三类——层状岩类,工程地质勘探的复杂程度划分为中等型,属工程地质条件中等矿床。
        The Tangba gold deposit lie in Wudu of Gansu province under Pipa jurisdiction. The climate is a warm temperate humid continental monsoon climate and water development in this district as the Jialingjiang water system of Yangtze River valley. The gold deposits in Tangba are situated in carbonate rocks and clastic rocks with hard and semi-hard feature. In general,some hard rocks keep intact such as tuff and siliceous breccia. These structure types of rock mass have in block fabric,the rocks are stably and the engineering conditions are quite good.However,the stabilities of the weak rooks such as phyllite as well as the rocks in certain influence of fractured zone are poor and the rock is cracking. Its structure type is mainly layered blocky and granular structure. The engineering geological exploration,bedded rock,is third category. Its complexity can be divided into middle type,which belongs to the medium ore deposit under these geological conditions.
