Inorganic grouting material for coal mine
The invention discloses an inorganic grouting material for a coal mine, which comprises two groups of slurry A and slurry B, and the two groups of slurry A and slurry B are mixed according to the same mass ratio to obtain the inorganic grouting material, the group A slurry is prepared from 90 to 100 parts of Portland cement, 10 to 20 parts of sulphoaluminate cement, 0.5 to 2 parts of a water reducing agent, 0.1 to 1 part of a thickening agent, 0.1 to 1 part of a retarder, 42 to 48 parts of a diluent, 0.1 to 0.5 part of a catalyst, 0.2 to 1.5 parts of a dispersing agent and 10 to 25 parts of a curing agent; the slurry group B comprises 70-80 parts of gypsum, 30-40 parts of lime, 3-5 parts of a water reducing agent, 2-5 parts of a retarder, 40-50 parts of a diluent, 1-5 parts of an accelerator, 0.5-1 part of a catalyst, 1-3 parts of a dispersing agent and 15-30 parts of a curing agent. The slurry A and the slurry B are combined, so that the slurry has the characteristics of high fluidity, rapid solidification, micro-expansion, high strength and the like, can rapidly permeate into coal cracks of surrounding rocks around drill holes, and has a good sealing effect.
本发明公开了一种煤矿用无机注浆材料，包括AB两组浆料，所述AB两组浆料按照相同的质量比混合使用得到无机注浆材料，所述A组浆料包括硅酸盐水泥90‑100份、硫铝酸盐水泥10‑20份、减水剂0.5‑2份、增稠剂0.1‑1份、缓凝剂0.1‑1份、稀释剂42‑48份、催化剂0.1‑0.5份、分散剂0.2‑1.5份和固化剂10‑25，所述B组浆料包括石膏70‑80份、石灰30‑40份、减水剂3‑5份、缓凝剂2‑5份、稀释剂40‑50份、速凝剂1‑5份、催化剂0.5‑1份、分散剂1‑3份和固化剂15‑30份。本发明通过将A组浆料和B组浆料进行结合，具有高流动性、快速凝固、微膨胀、强度高等特性，能迅速渗入钻孔周边围岩煤裂隙，具有良好的密封效果。
