Abstract

In a post-mining water-resisting layer reconstruction method through partition grouting for a coal-measure aquifer in coal seam roof strata, a precise analysis of hydrogeological characteristics of overlying strata may be achieved by comprehensively considering geological parameters and strata distribution parameters of a target mining area. Subsequently, a development height of a water-conducting fracture zone may be determined by utilizing distribution feature algorithms and numerical simulation algorithms. Further, an analysis of a correlation between the water-conducting fracture zone and the hydrogeological characteristics may be conducted through a distribution relationship algorithm. In this method, by implementing a target grouting control strategy based on distribution relationships for post-mining coal seam roof strata, the precision of water hazard control may be significantly enhanced. Further, a related post-mining water-resisting layer reconstruction device is also disclosed.
