Probability Integral Prediction and Numerical Simulation of Surface Subsidence in Bed Separation Grouting and Filling Mining in Changcun Coal Mine
Taking the No.2311 working face of Changcun Mine as the research object,this pa-per compares and analyzes the degree of surface subsidence caused by mining with and without bed separation grouting through probability integral prediction and discrete element numerical simulation.The results show that surface subsidence can be effectively controlled.The technolo-gy can effectively control surface subsidence and improve the recovery rate of coal resources.
