摘要
封孔材料及工艺是决定瓦斯抽采效果的关键技术之一,针对含水煤层瓦斯抽采钻孔封孔质量差的难题,采用新型封孔材料,配合封孔袋的隔水作用及改进的封孔工艺,可有效封堵有水钻孔,保证矿井瓦斯抽采的效果。
Sealing material and process is one of the key technologies to determine gas drainage effect. Aiming at the problem of poor sealing quality of gas drainage drilling in hydrous seam, using new sealing material with the impermeable role of sealing bags and the improved sealing process, the drilling fulled with water can be sealed effectively, which can ensure the gas drainage effect.
