High-strength quick-setting material for grouting of complex stratum in underground coal mine as well as preparation method and application of high-strength quick-setting material
The invention relates to a high-strength quick-setting material for grouting of an underground complex stratum of a coal mine and a preparation method and application of the high-strength quick-setting material, and belongs to the technical field of coal mine drilling. The material comprises the following components in parts by weight: 30-150 parts of aluminate cement, 50-100 parts of blast furnace slag, 0.1-1 part of a dispersing agent, 1-30 parts of a lightening agent, 1-10 parts of an activating agent, 0.1-0.5 part of a suspension stabilizer, 1-3 parts of a retarder and 60-120 parts of water. The material retains part of characteristics of aluminate cement, a solidified body with strength can be formed, and the early strength is stably guaranteed; due to the introduction of the blast furnace slag, the hydration heat release of an aluminate cement system is remarkably reduced, the later strength of a material forming a solidified body is ensured not to decline, and the material can be used within the temperature range of 25-80 DEG C. The material has the advantages of being high in hardening speed, good in fluidity, moderate in viscosity, short in thickening time and the like, the strength of a solidified body in one day is larger than 5.5 MPa, the sealing requirement in coal mine underground complex stratum drilling operation is met, and the material is suitable for drilling sealing in different stratum environments.
本发明涉及一种煤矿井下复杂地层注浆用高强度速凝材料及其制备方法和应用，属于煤矿钻探技术领域。该材料按重量份计，包括如下组分：30‑150份铝酸盐水泥、50‑100份高炉矿渣、0.1‑1份分散剂、1‑30份减轻剂、1‑10份激活剂、0.1‑0.5份悬浮稳定剂、1‑3份缓凝剂、60‑120份水。材料保留了铝酸盐水泥的部分特性，可以形成具有强度的固化体，早期强度有稳定的保证；高炉矿渣的引入显著降低了铝酸盐水泥体系的水化放热量，保证了形成固化体的材料后期强度不会衰退，能够使材料在25‑80℃的温度范围内进行使用。该材料具有硬化速度快，流动度好，粘度适中，稠化时间短等优点，一天的固化体强度大于5.5MPa，满足了煤矿井下复杂地层钻孔作业中封固要求，适用于不同地层环境下的钻孔封固。
