【Abstract】 In this paper, the authors have analyzed and studied the distregulation and the lithology of the third aquifuge of the Quaternary system in the 810 mining area of Luling Mine. By means of the mineralogical analysis and the sticky indexes and the permeability testing, the authors found out that the third aquifuge had better impermeability and can prevent effectively the groundwater of the third aquifer from infiltrating to the mining area.更多还原
