水压爆破在隧道开挖中的应用研究

Application of energy saving hydraulic blasting in tunnel

节能环保水压爆破技术属建设部科技成果推广项目,王家沟隧道开挖施工中采用该项技术,介绍其爆破施工工艺流程,总结相关施工要点和质量控制要求,最后将常规爆破和节能环保水压爆破的爆破效果进行了对比分析,该爆破法可充分利用炸药能量,有利于岩石破碎,块度均匀,有效控制飞石,缩短爆堆距离,提高隧道掘进施工效率,水的雾化还能起到降尘作用,具有一定推广价值。

The energy saving hydraulic blasting technology is the Ministry of Construction projects to promote scientific and technological achievements, the tunnel excavation and construction Wangjiagou adopt the technology, introduced its blasting construction process, summarize the main points related to the construction and quality control requirements, and finally conventional blasting and conservation environmental hydraulic blasting blasting effect a comparative analysis, the method can make full use of dynamite blasting energy is conducive to rock fragmentation, fragmentation uniform, effective control of flying rocks, rock pile shorten the distance, improve the efficiency of tunneling construction, water atomization dust can also play a role, with some promotional value.
