摘　　要：目前复兴村金矿区已完成部分详查工作,未来的开采必然引发一系列工程地质问题。矿区地表风化强烈、裂隙发育,断裂构造较发育,岩石质量较好,岩体质量较差,工程地质环境质量属于较差—中等。依据岩性、岩石力学性质将工程地质岩组划分为第四系松散岩类岩组,较坚硬薄层变质岩岩组、坚硬块状碳酸盐岩组、坚硬块状火山岩组,边坡及地下采空区围岩的稳定性是主要的工程地质问题。对可能存在的工程地质问题进行了预测并提出相应问题的防治建议,为后续的矿山开采技术条件提供必要的依据。So far part of the general exploration has been completed in Fuxingcun Gold Deposit, which suggests future mining will inevitably cause a series of problems about engineering geology. The faults develop well ,the surface weathers strongly and cracks grow, rock quality is good while rock body poor, all the above makes the environmental quality of engineering geology is of poor-moderate grade＇in the region. According to the property of lithology and mechanics, the rocks can be grouped into the Quaternary lax rocks, relatively hard and thin metamorptlic rocks, hard lump carbonate rocks and hard lump volcanic rocks in engineering geology. The stability of surrounding rocks in slope and underground mined-out area is the main engineering geological problem. The paper predicts the possible environmental engineering geological problems and proposes corresponding prevention recommendations to provide the basis for con- struction and development of the mine.
