Coal seam gas extraction hole sealing material and preparation method and construction method thereof
The invention belongs to the technical field of coal seam gas control, and discloses a coal seam gas extraction hole sealing material, a preparation method and a construction method. The hole sealing material comprises a component A and a component B, the component A comprises the following components: ordinary Portland cement, calcium sulphoaluminate, a polymer emulsion, quick lime and bentonite; and the component B comprises the following components: glass beads, hydroxypropyl methyl cellulose and an auxiliary agent. The hole sealing material disclosed by the invention has relatively good fluidity and short solidification time, the safety meets the requirements of a mining hole sealing material, and the sealing effect and the gas drainage efficiency of a coal seam gas extraction drill hole are improved.
本发明属于煤层瓦斯治理技术领域，公开了一种煤层瓦斯抽采封孔材料及制备方法和施工方法。该封孔材料包括A组分和B组分；所述A组分包括如下组分：普通硅酸盐水泥、硫铝酸钙、聚合物乳液、生石灰和膨润土；所述B组分包括如下组分：玻化微珠、羟丙基甲基纤维素和助剂。本发明的封孔材料具有较好的流动度，凝固时间短，安全性达到矿用封孔料的要求，提高了煤层瓦斯抽采钻孔的密封效果和瓦斯抽放效率。
