Abstract:
Due to the early non-standard and large-scale mining in Binchang Mining Area, local farmland has suffered from cracks, subsidence, and house damage. The production of rapeseed and wheat has decreased, making it impossible to farm normally, which has severely affected daily life and production, drawing significant attention from the local government. To address the increasingly prominent geological disaster issues of mining collapse in Binchang Mining Area, based on a thorough analysis of the development height and water isolation properties of the water-conducting crack zone, a combined approach of blocking and drainage is proposed. This method involves injecting grouting pipes within relatively isolated aquifers for sealing and drilling peripheral holes for drainage, with phased construction. Project applications have shown that the grouting technology for mining collapse in Binchang Mining Area is feasible, with good treatment results. This also provides valuable reference for similar future mining collapse control projects.
