Simulation of micromechanical characteristics of coal seam grouting based on particle flow method
Grouting method is one of the commonly used methods for soft roadway reinforcement. Through the discrete element simulation method, the grouting process of coal seam was studied, and the grouting effect under different coal strength and grouting pressure was explored, and the diffusion form of the...
