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。
This paper discusses the layout parameters and process of loose holes and gas drainage holes in deep holes, and designs the implementation plan. The application test at Pan Mine shows that it is a good way to improve the gas drainage effect of low permeability coal seam by using deep hole loose blasting technology.
