针对目前瓦斯抽采钻孔封孔材料封孔质量差、抽采浓度低、材料强度低、固结时间长等缺点,以硫铝酸盐水泥熟料、石灰和石膏为主料,并辅以改性材料,研发了一种新型无机双液瓦斯抽采钻孔封孔材料。该材料固化速度快、强度高、渗透性强,具有微膨胀性能,能够有效将孔内封实,消除孔内漏气通道。该新型材料在抽采钻孔封孔领域具有良好的应用前景。
In view of the shortcomings of poor sealing quality, low pumping concentration, low material strength and long consolidation time of the gas drainage drilling plugging material, the main material of the gas drainage drilling plugging material is sulphoaluminate cement clinker, lime and gypsum, supplemented by Modified materials, developed a new inorganic double-liquid gas drainage drilling sealing material. The material has the advantages of fast curing speed, high strength, strong permeability and slight expansion property, which can effectively seal the hole and eliminate the leakage channel in the hole. The new material has a good application prospect in the field of drilling and hole sealing.
