摘　　要：在收集大量文献资料的基础上,对乌审旗一带刘家沟组作为高矿化度矿井水回灌目的层的可行性进行了分析。通过研究分析得出,①刘家沟组存在可供矿井水回灌运移通道和空间,能够满足矿井水回灌的空间需求;②回灌目的层刘家沟组距离志丹群含水层垂直距离约1800 m,采取一系列措施后基本不会对含水层产生影响,在确保“良水回灌”前提下,亦不会造成刘家沟组水质恶化;③刘家沟组与煤层和油气层垂直距离较大,正常情况下回灌不会对其产生影响;④刘家沟组作为乌审旗一带回灌目的层从储集空间和环境影响上都是可行的,所以采取一定措施后,刘家沟组作为矿井水回灌目的层是可行的。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.
