深孔松动爆破提高瓦斯抽放率的应用研究

Applied Study on Deep Hole Standing Shot to Improve Methane Drainage Efficiency

本文探讨了深孔松动爆破孔和瓦斯抽放孔的布置参数及工艺等 ,并设计了实施方案。在潘一矿的应用试验表明 ,用深孔松动爆破技术来提高低透气性煤层的瓦斯抽放效果 ,是一条很好的途径。

In this paper, layout parameters and technology of deep hole standing shot and methane drainage holes is discussed and implemented plan is designed, test in Panyi Coal Mine shows that it is a very good path to improve methane drainage efficiency by using deep hole standing shot technology in low permeability coal seam.
