Abstract On the basis of collecting a large amount of literature, the feasibility of the Liujiagou Group as a destination layer for mine water recharge with high mineralization was analyzed. It was concluded that (1) the Liujiaogou group had a transport channel and space for mine water recharge, which can meet the spatial demand for mine water recharge; (2) the Liujiaogou group was about 1,800 m away from the Zhidan aquifer, which would not affect the aquifer after taking a series of measures, and not have any impact on the aquifer to ensure good water recharge;(3) The vertical distance between Liujiagou formation and coal seam gas layer was large, and the recharge would not affect it under normal circumstances;(4)
Liujiagou Group is feasible as a recharge destination layer in terms of storage space and environmental impact, so it is rensonable to recharge Liujiagou Group as a mine water recharge destination layer after taking certain measures.
