  • There are various problems caused by environmental pollution around the abandoned mines. In addition, they are exposed to the risk of safety accidents due to sinkholes caused by ground subsidence. Therefore, the ground is stabilized through the filling and construction of abandoned mines using industrial by-products. However, in the case of Backfill Material, secondary pollution caused by acidic drainage and leachate is not suppressed. To solve this problem, the liner and cover material is first installed. Therefore, in this study, the watertightness of the liner and cover material was improved by mixing crystalline admixtures by content.
