Application of Longhole Shock Blasting Technique in 5413_Ⅱ~s Gate Construction

简要介绍了深孔松动爆破的作用机理,以及该技术在5413Ⅱs顺槽高突掘进头施工中应用,增加了煤层的透气性,大大提高了抽放效果,加快了掘进速度,为高突掘进工作面的防突提供了一成功范例。

This paper gives a brief description of the action mechanism of long-hole shock blasting and its application in 5413IIS gate construction of serious outburst heading face. The application of this measure increased the gas permeability of coal seam, greatly raised gas drainage effectiveness, speeded up drivage rate and provided a successful example for outburst prevention in serous outburst heading face.
