Abstract: Based on systemic and detailed survey research on hydrological geologic、engineering geologic and environmental geologic of Xiaohe-Shimenkan ore block of Liuju copper mine, The study results show survey area ore deposit was cranny hydrated stratum. Water-filling intensity of ore deposit was weak. It belonged weak water characteristic ore deposit. mass stability of Xiaohe-Shimenkan is better, geologic complication-degree was simple. Environmental ge-hazards of survey area and ore deposit exploiting area didn't obviously develop. It can afford reference warranty for future whole engineering lay and ore deposit mining method option.
