Mining sealing material as well as preparation process and application thereof
The invention provides a mining sealing material as well as a preparation process and application thereof, and relates to the field of sealing materials. The mining sealing material provided by the invention is prepared from the following raw materials in parts by weight: 25 to 45 parts of slag, 5 to 15 parts of Portland cement clinker, 15 to 40 parts of auxiliary materials, 5 to 20 parts of gypsum, 3 to 15 parts of lime, 0.1 to 2 parts of grinding aid, 1 to 5 parts of activating agent, 0.1 to 5 parts of adhesion promoter, 0.3 to 3 parts of anti-cracking agent and 0.5 to 5 parts of reinforcing agent. The sealing material is high in setting speed, good in fluidity and good in water retention, construction difficulty is reduced, gas leakage is not prone to occurring, hole sealing quality is good, safety meets the requirements of mining hole sealing materials, and therefore the sealing effect and gas drainage efficiency of coal seam gas extraction drill holes are improved, and raw material sources are wide. The preparation method is simple, and the production cost is reduced; meanwhile, the application is simple, the construction difficulty is reduced, and the hole sealing period is short.
本发明提出了一种矿用密封材料、制备工艺及其应用，涉及密封材料领域。本发明提供的矿用密封材料，按重量份数计其包括以下原料：矿渣25‑45份、硅酸盐水泥熟料5‑15份、辅料15‑40份、石膏5‑20份、石灰3‑15份、助磨剂0.1‑2份、活化剂1‑5份、附着力促进剂0.1‑5份、抗裂剂0.3‑3份以及增强剂0.5‑5份。凝结速度快，密封材料的流动度良好，保水性好，减小了施工难度，不易漏气，封孔质量良好，安全性均达到矿用封孔料的要求，从而提高了煤层瓦斯抽采钻孔的密封效果和瓦斯抽放效率，原料来源广泛；制备方法简单，降低了生产成本；同时，本发明提供的应用简单，减小了施工难度，封孔周期短。
