Abstract

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.

Description

technical field [0001] The invention relates to an anchoring agent, in particular to a resin cement for the anchoring agent and an anchoring agent, which are used for anchoring large-diameter anchor cables used in coal mine roadway support and underground engineering protection construction. Background technique [0002] In coal mine construction projects, in order to ensure construction safety, the roadway must be supported by anchor nets, that is, anchor rods, anchor cables, metal mesh, steel belts, etc. are used to form a support system, and the anchor rods and anchor cables are anchored by drilling holes. The agent anchors it to the rock formation to form a pressure-bearing ring. [0003] At present, the anchoring agent used in coal mine bolt support in my country is divided into cement anchoring agent and resin anchoring agent. The resin anchoring agent is composed of resin cement and curing agent, also known as two-component glue. The resin cement is made of unsaturate...
