Hole sealing material for gas drainage hole and preparation method
The invention discloses a hole sealing material for a gas drainage hole and a preparation method, and belongs to the field of coal mining. The hole sealing material is prepared from the following raw materials in parts by mass: 100 parts of a gelling component, 1.6 to 4.5 parts of a gelling admixture, 100 parts of an exciting component and 2.06 to 2.10 parts of an exciting admixture. The invention provides a novel gas hole sealing material which has good two-stage expansion performance and air tightness, is non-toxic and harmless and is low in price, and gas extraction can be completed in a high-concentration and high-efficiency manner. The novel hole sealing material has the characteristics of no segregation, no bleeding, no shrinkage and the like, and solves the problem of water seepage after grouting.
本发明公开了一种用于瓦斯抽放孔的封孔材料及制备方法，属于煤炭开采领域。所述封孔材料的原料按质量份数计，包括：胶凝组分100份、胶凝外加剂1.6‑4.5份、激发组分100份和激发外加剂2.06‑2.10份。本发明提供了一种具有良好双阶段膨胀性能、气密性，无毒无害，价格便宜的新型瓦斯封孔材料，可以高浓度、高效率的完成瓦斯抽采。此新型封孔材料具有不离析、不泌水和不倒缩等特性，解决了注浆后渗水问题。
