一、Product overview

This product is a kind of two-component inorganic powder, fast setting, early strength, the use of grouting pump into broken coal rock mass, fast reinforcement of loose coal rock mass, prevent flake. It can be used for grouting reinforcement of coal working face, fault grouting reinforcement of working face, grouting reinforcement of small coal pillar along goaf (no need to advance grouting), full anchor support of roadway affected by high stress and mining (including original support), it can also be used for filling reinforcement of mountain, tunnel, brick wall, concrete, as well as non-flowing sand and other ground reinforcement without bearing capacity. It is mainly used for reinforcement of broken roof and coal seam in mining face and can replace polymer materials used for reinforcement of coal and rock mass.

二、Scope of application

It is suitable for rapid reinforcement of coal and rock mass in crushing working face

It is suitable for the advance and pre-reinforcement of coal rock mass during the coal uncovering period of roadway driving
