【Abstract】 In order to obtain the optimal grouting parameters, BIM-based technology was used to realize the numerical simulation of collapse and grouting reinforcement risk in underground metal mines. The 3^rd section of №1 stope in the middle section of the main ore body of a lead-zinc mine was selected for the numerical simulation of grouting reinforcement. The numerical simulation results showed that the slurry diffusion radius increased with the increase of grouting pressure and grouting time, and the optimal chemical grouting parameters were determined based on the numerical simulation results. As a result, the rock mass quality in the collapsed area is significantly improved after grouting with the determined chemical grouting parameters.更多还原
