光面爆破技术在坚硬顶底板半煤岩巷道施工中的应用

Application of Smooth Blasting Technology in Construction of Hard Roof-to-floor Coal-rock Drift

以慈林山煤矿9号煤层轨道大巷实际施工为例,介绍了施工中坚硬顶底板半煤岩巷道光面爆破参数的选择、调整,从理论和实际施工情况分析、介绍了光面爆破的优点以及在实际施工过程中技术管理的重要性。

Taking the actual construction on main roadway of Cilinshan No. 9 coal seam track for example, it presents the choice and adjustment of smooth blasting parameter in contraction for hard roof - to - floor coal - rock drift. Meanwhile, it analyses and introduces the advantage of smooth blasting with the theoretic and actual condition, and stresses the importance of technical management in the process of real construction.
