The invention relates to an anchoring agent, which is resin
mortar for an anchoring agent and the anchoring agent, and is used for anchoring large-
diameter anchor cables used in the construction of the support of
coal mine roadways and the protection of underground
engineering. The resin
mortar comprises the following compositions in portion by
mass: 800 to 1,200 portions of MG
unsaturated polyester resin, 4,000 to 6,000 portions of limestone
powder, 3 to 10 portions of
dimethylaniline, and 6 to 12 portions of white
carbon black, wherein the particle size of the limestone
powder is between 80 and 120 meshes. The resin
mortar and a curing agent form a bi-component anchoring agent. The anchoring agent can effectively reduce the consistency of the resin mortar, and improve the
compressive strength after the solidification of the anchoring agent, thereby realizing the effects during the use such as high
adhesive force, low stirring resistance and the like; and the anchoring agent meets the requirement of using large-
diameter and high-strength anchor cables in the support of the
coal mine roadways, reduces anchoring length, construction time and construction personnel, and improves the production efficiency.
