摘要
光面爆破在岩巷施工中,已经有了成形的理论和经验,而在煤巷施工中有待于进一步探讨和研究。以双河煤矿三水平8#皮带道采用光爆施工为例阐述了光爆在煤巷施工中的具体应用。
The appliction of smooth blasting to rock tunnel already has normal theory and experience, but the appliction of smooth face blasting to coal tunnel will be farther studied. Take the three - level 8# seam, Shuanghe Coal Mine for example, sets forth the detailed application of smooth blasting to coal tunnel.
