Experimental study on mechanical properties and microstructure of cement-based expansion grouting materials for broken coal mass.
As the excavation depth of the tunnel increases, the stress on the surrounding rock increases, and the tunnel becomes fragmented, especially in coal tunnels, which require grouting reinforcement. Conventional materials are inadequate for the grouting and reinforcing demands of this type of surroundi...
