摘要
瓦斯抽采是最常采用的瓦斯治理手段,抽采钻孔的钻深、孔径、钻孔存留时间直接影响瓦斯抽采效果。本文主要针对松软突出煤层钻进技术面临的难题,施工过程中使用的装备,总结提高钻进功效的有利经验。
Gas drainage is the most commonly used means of gas control. Drilling depth of drill hole, aperture, drilling retention time directly affect the effect of gas extraction. This paper focuses on the difficult problems of the drilling technology of soft and outburst coal seam and the equipment used in the construction process, and summarizes the beneficial experience of improving the drilling efficiency.
