Mining inorganic reinforcing material and preparation method thereof
The invention relates to the technical field of materials, and discloses a mining inorganic reinforcing material which comprises the following components in percentage by mass: 21.9%-27.3% of water, 37.5%-38.3% of sulphoaluminate cement, 1.2%-2.0% of sodium carbonate, 3.9%-5.9% of lime, 19.5%-26.6% of gypsum, 7.8%-11.7% of stone powder and 0.8%-1.2% of a water reducing agent. The invention further discloses a preparation method of the mining inorganic reinforcing material. The material is a pure inorganic material, the reaction temperature is low, and the ignition risk is avoided. In the material solidification process, bleeding and precipitation are avoided, and good fluidity and high groutability are achieved. After the material is injected into a coal-rock mass, the bearing capacity of the coal-rock mass can be quickly improved.
本发明涉及材料技术领域，公开一种矿用无机加固材料，包括质量百分比的以下组分：水21.9％～27.3％，硫铝酸盐水泥37.5％～38.3％，纯碱1.2％～2.0％，石灰3.9％～5.9％，石膏19.5％～26.6％，石粉7.8％～11.7％，减水剂0.8％～1.2％，并公开了其制备方法。本发明中的材料为纯无机材料，反应温度低，无着火风险。材料凝固过程中不泌水、不沉淀，具备良好的流动性和较强的可注性；注入煤岩体后，能够快速提高煤岩体承载能力。
