摘要
在松软突出煤层钻进中,采用中风压空气钻进技术在工艺及配套装备方面具有明显的优势。通过在平煤某矿的应用,解决了钻孔深度不足、孔内事故预防及处理难度大等问题。实践证明,中风压空气钻进技术在松软突出煤层中值得推广。
Drilling in soft and outburst coal seam,the medium pressure air drilling has obvious advantages in technology and supporting equipment.Through the application of this technology in Pingdingshan coalmine,borehole without enough depth,borehole accident prevention and accident treatment difficulties were effectively resolved.The practice showed that the medium pressure air drilling technology is worth popularizing in soft and outburst coal seam drilling.
