The overlying rock strata isolation grouting filling technology is introduced,aimed at addressing issues such as surface construction,roads,and rivers being impacted by coal mining activities,resulting in coal compression,severe resource wastage,and associated problems including surface subsidence and ecological degradation.A filling technique involving injecting slurry material between rock strata to fill voids was designed,thereby stabilizing the surface,alleviating surface pressure,and preventing surface collapse.The study focused on the technical principles and key stages of construction,validating the effectiveness of the technology through on-site practical experiments.Analysis encompassed the working principles of the technology,as well as the materials and methods for grouting filling.The application scope of this technology primarily lies in surface engineering within coal mining areas,offering significant economic and societal benefits.Compared to conventional methods,this technology more effectively addresses issues such as surface subsidence and ecological damage while also reclaiming the original coal mining areas,thus reducing resource wastage.Practical application has led to the conclusion that this technology is feasible and superior in actual implementation.
