TY - Data T1 - Test data set for modification and reconstruction of water-retaining layer in alpine Kuangqu mining area (2023-2024) A1 - li cheng A1 - sun zhi long PY - 2026 DA - 2026-07-06 PB - National Cryosphere Desert Data Center AB - The large-scale coal mining in high-altitude mining areas has caused serious damage to surface vegetation, permafrost layers, water resources, etc., and the ecological restoration of mining areas lacks necessary soil resources. Utilizing the solid waste resources of coal gangue in mining areas as the main material for reconstructing the coal gangue matrix, optimizing the hydraulic characteristics of the reconstructed coal gangue matrix through the addition of functional materials is of great significance for water conservation and vegetation restoration in high-altitude mining areas. Research on using coal gangue as the main material for water retention layer reconstruction, screening several specifications of main materials, and conducting water retention layer reconstruction experiments by adding functional materials. The data includes the water holding capacity, porosity, saturated hydraulic conductivity, evaporation, etc. of different main materials, as well as the water holding capacity, porosity, saturated hydraulic conductivity, wetting front transport depth, cumulative infiltration, daily evaporation, cumulative evaporation, profile water content distribution after evaporation, water holding coefficient, etc. of different functional materials added to reconstruct the water retaining layer. The reconstructed water retaining layer model based on coal gangue as the main material provides hydraulic parameters.
