Low-temperature reinforcement materials for mines Low-temperature reinforcement materials for mines are produced by mixing and reacting two-component substances at a volume ratio of: under low-temperature conditions. They are specially used to reinforce broken rock formations in coal mines or tunnels. After the material is injected into the formation, it can quickly penetrate fine cracks, expand and solidify, and use its excellent connection and cementing properties with the rock to connect the broken rocks into a whole, increasing the solidity and support of the rock formation. And it can quickly solve various formation problems with safety risks. Prevent accidents such as roof breakage and roof collapse, gas outbursts and water leakage, and ensure production safety. It is easy to use, can effectively simplify the construction process, save construction time and reduce construction costs.
Scope of use
, Reinforcement of tunnels or tunnels and compressed coal pillars
, Reinforcement of broken coal and rock when the working face passes through faults
, Reinforcement of working face supports or Broken rock layer at the top of the tunnel
, filling and reinforcing the high risk area of the tunnel
, reinforcing and sealing the surrounding rocks of various cave chambers underground
, and sealing the gas drainage holes.
Material features
, strong adhesion, fast bonding to the formation
, low viscosity, easy to penetrate cracks
, high elasticity, not damaged by formation movement
, fast The performance indicators are met and the construction is rapid.
