The silicate-modified polyurethane material for reinforcing coal and rock masses in coal mines is developed to address issues such as roof collapse and maintenance at coal mine working faces, roadway deformation reinforcement, and surrounding rock reinforcement under adverse geological conditions. It consists of two components, A and B, which are mixed in a volume ratio of 1:1 and undergo a rapid reaction to form a consolidated body with high strength and certain toughness. This consolidates the originally loose and discontinuous coal and rock masses into a continuous and integral stress-bearing unit, thereby achieving the reinforcement effect.

Lianshi Inorganic Coal and Rock Reinforcement Material (KWJ-Ⅰ) can fully fill and reinforce broken coal and rock masses, and eventually form a dense consolidated body integrated with the coal (rock) mass. It is used for filling and reinforcing cracks in mountain bodies, tunnels, brick walls, concrete, as well as coal and rock in mines. It is especially applicable when passing through faults, and can also be used for non-flowing sand, gravel and other ground with no bearing capacity.

This product consists of two components, Component A and Component B, which are mixed and used in a volume ratio of 4:1. The chemical reaction during the reaction process is mild with low heat generation, and the surface temperature rise before and after the reaction is within 5 degrees Celsius. It has a low initial viscosity. After being injected into the space of fractured coal and rock mass, it has excellent diffusion and penetration performance. The final generated solid can form a firm consolidated body with the coal and rock mass, featuring high compressive strength and good elastic deformation resistance. It efficiently enhances the integrity and supporting capacity of the coal and rock mass, ensuring the safe production of the mine.
