Abstract
Xincheng gold deposit is located in Xincheng Village of Jiaodong, Laizhou Jincheng, near Bohai Bay, and is one of the largest mines in China. The orebodies of Xincheng gold deposit located in Jiaojia fault zone are mainly located in the pyrite sericite-quartzized cataclasite belt and the pyrite-sericite-quartzized granodioritic cataclasite belt under the main fault plane (Fault Gouge). Based on the exploration data and test data, the occurrence characteristics of I and V major orebodies in the deposit are analyzed, and the mining evaluation is made on the basis of the hydrologic and environmental characteristics of the deposit. The results show that the rock of the Orebody, roof and floor is mainly massive igneous rock and Metamorphic Rock, which has high mechanical strength and is hard and semi-hard rock with simple engineering geological conditions The Ore and waste rock are not easy to decompose harmful substances, have no heat harm, the possibility of local surface deformation caused by mining is not big, the circulation of groundwater is bad, the evaporation is big, the water quality is bad, the mined-out area formed by mining has little influence on the stability of rock mass in the mining area. The main ore body in the study area is of good geological environment.
