Abstract: This paper analyzes the hydrogeological characteristics and dynamic groundwater changes in the mining area.The type of hydrogeological exploration is determined.The water source conditions for water supply in the mining area are evaluated.The stability of the ore body structure,the roof and floor as well as the surrounding rock of main roadways is analyzed,so as to determine the engineering geology type;through the analysis of the natural environment,earthquake intensity and its environment,the environmental geological classification of the mine area is further clarified.This paper basically explains the technical conditions for deposit development and provides a basis for mine construction.
