顺层钻孔一体式布囊封孔试验研究

Bedding Borehole One-piece Cloth Encapsulated as Experimental Study

瓦斯抽采是防治煤矿瓦斯灾害的根本措施,也是开发煤层气资源的重要手段,其中,顺层钻孔是煤矿抽采瓦斯的一种重要布孔方式。研究表明,定点定长布囊带压封孔新技术有助于增加封孔的气密性,增加钻孔瓦斯浓度,降低封孔成本,扩大瓦斯抽采能力,提高瓦斯抽采率,缩短抽采达标时间。

The gas extraction is a fundamental measures of prevention and control of coal mine gas disasters is also an important means of development of coalbed methane resources, among them, the bedding drilling is a kind of important gas of coal extraction holes. Suggests that capsule fixed-point fixed-length cloth with pressure sealing hole new technology has helped increase the tightness of hole sealing, increase drilling gas concentration, reduce the cost of sealing hole expanding gas extraction ability, improve the gas extraction rate and shorten the extraction amount to mark time.
