The paper determined the main water filling aquifer and water filling factors of the deposit, and pointed out the direction of the mining area water supply source; carried out mechanical test for the main rock and orebody roof and floor rock, evaluated the engineering geological conditions of host rocks of the ore bodies and top and floor rock and identified the effect of structural fracture belt and soft interlayer on the ore mining; slope stability of open pit was briefly evaluated; deposit hydrogeology, engineering geology and environmental geology exploration were divided into several types, which can provide the basis for economical and technkal evaluation of ore deposits, and feasibility and general plan of mine construction in the future.
