Shanxi coal mine reinforcement materials and construction, Shanxi Maosen Mining

Mining reinforcement material is a two-component polymer slurry used to reinforce soft and broken rock formations that are prone to flaking coal walls. With its controllable expansion rate, high bonding strength and high safety of use, it plays an irreplaceable role in the reinforcement of surrounding rock. The material is injected into the formation using double-liquid grouting at a ratio of: After injection, the low-viscosity liquid penetrates into the fine cracks and expands and solidifies at the same time for the purpose of reinforcement.
Scope of use
Reinforce broken surrounding rock tunnels
Reinforce the excavation working face in advance to deal with roof collapse
3 Control the mining working face area
Reinforce the coal-rock triangle area.
Material Features
Controllable expansion rate: Reduce the amount of material and at the same time play a self-emitting effect. Fully fill the cracks
Strong adhesion: quickly and firmly bond the coal seam
3 Low viscosity: easily penetrate into micro-cracks
High toughness: enough to adapt to changes in the rock formation
Quick reflection and solidification: improve overall production efficiency.
