摘要
针对老挝爬奔金矿的工程地质条件及水文地质条件展开调查,首先根据地质调查与钻探揭露其地层岩性,分析其地层分布、岩土体特性和地质构造,分析了地表水、地下水腐蚀性,认识了爬奔金矿矿区的工程地质特征;其次对矿区潜在地质灾害进行野外调查、分类,对矿区边坡稳定性进行了分析,同时分析了矿区的地质灾害危险性等级,并提出了相对的防治措施。
Investigation of engineering geological and hydrogeological condition in Phapon gold mine, Laos. Firstly, based on geological survey and drilling, analyzing the distribution of stratigraphic lithlogy, rock features, geological structure, and corrosion to concrete and rebar by water. From this research, the engineering geological features were systematically studied. Then, the geological hazards distributions were analyzed by used geological survey and classification. And also, the slope stability was drawn and calculation by used stereographic projection method and circular arc method, respectively. At last, the geological hazards risk grade and corresponding prevention measures were proposed in Phapon gold mine.
