This product is a kind of inorganic powder with strong injectivity. It can be used to fill and reinforce coal body, rock mass, mountain, tunnel, brick wall, concrete and other cracks by pressure injection method, and strengthen underground faults and working faces by pre-grouting.
一、Product overview
This product is a kind of inorganic powder with strong injectivity. It can be used to fill and reinforce coal body, rock mass, mountain, tunnel, brick wall, concrete and other cracks by pressure injection method, and strengthen underground faults and working faces by pre-grouting. It can also be used for non-flowing sand and stone and other non-bearing ground reinforcement. It is mainly used for advance grouting reinforcement of underground faults, working face over faults, mining small coal pillar grouting reinforcement and filling reinforcement of roadway that may be affected by dynamic pressure.
二、Scope of application
Suitable for permanent roadway in high stress area
The surrounding rock reinforcement of small coal pillar is suitable for soft coal, soft rock and other broken coal roc
It is suitable for repairing roadway deformation caused by ground pressure and mining
It is suitable for strengthening loose coal rock with low strength, easy weathering and low degree of cementation
三、產(chǎn)品特點(diǎn)
