摘要
针对常规封孔工艺在瓦斯抽采过程中存在的弊端和“两堵一注”囊袋式封孔装置造价偏高以及对封孔设备和操作要求较高等问题,拟研究一种经济实惠、操作便捷兼有两堵一注封孔优势的便携式两堵一注全程下筛管的高效封孔技术,经现场应用与对比试验,分析得出:该封孔技术较之两堵一注囊袋封孔经济实惠,且操作便捷,瓦斯抽采浓度、抽采量对比常规封孔方式有显著提高,为矿井的高效、经济地治理瓦斯提供了有力保障。
In view of the disadvantages of the conventional hole sealing process in the process of gas drainage and the high cost of the "two plugging and one injection" bag type hole sealing device and the high requirements for hole sealing equipment and operation, it is proposed to study a portable two plugging and one injection high-efficiency hole sealing technology with the advantages of two plugging and one injection hole sealing. After field application and comparative test, the analysis shows that the hole sealing technology is more economical and convenient than two plugs and one injection bag sealing,and the gas drainage concentration and volume are significantly improved compared with the conventional hole sealing method, which provides a strong guarantee for the efficient and economic gas control of the mine.
