带压封孔技术提高瓦斯抽放效果的试验研究
Experimental Study on the Pressure Sealing Technology Increasing Effect of Gas Drainage
摘要
Abstract
Gas concentrations drop,and the effective gas drainage period of holes is shortened,because quantities of gas leaking cracks form under the pressure of tunnel drilling perturbation,borehole perturbation and gas absorption of the hole.The Pressure Sealing Technology is proposed as a solution to this problem.The principles are described and the hole-sealed technology parameters are attained by theoretical analysis.An industrial scale test of this methodwas carried out over a period of three months at No.10 mine mine of the Pingdingshan Mine Industry Group.The gas drainage concentration was improved by 40 to 65% after application of the method and the period of effective gas drainage was extended for 1-2 months.关键词
