隧道掘进水压爆破施工技术

摘要

对常规爆破和掘进水压爆破技术的爆破参数以及两种爆破方法的技术指标及经济指标进行对比分析，并对掘进水压爆破的工艺流程、爆破参数、装药结构、材料用量以及三种爆破炮眼装药结构进行对比分析，总结得出掘进水压爆破施工技术的注意事项，以利此技术地应用推广。%In this paper, first, the technical and economic index of the conventional blasting technology and water pressure blasting technology are compared and analyzed. Then, the process flow, the blasting parameters, the charging structure, the material dosage and the charging structure of three different blasting perforations are analyzed. Finally the precautions of water pressure blasting technology are introduced.
