摘要
爆破工艺是巷道掘进最常见的施工工艺之一,若爆破参数计算不准确、炮眼布置不合理以及爆破防护措施不到位,都会影响巷道掘进效率和质量标准化。西山煤电集团屯兰矿开拓四队在施工12505系统巷时对爆破施工工艺进行分析研究,并制定合理的爆破防护措施,力求保证巷道安全高效施工。
Blasting is one of the most common construction technology of tunnel excavation if the calculation of blasting parameters is not accurate, the borehole layout is not reasonable and blasting protection measures is not in place, will affect the tunneling efficiency and quality standardization. Xishan Coal and electricity group, fourth development team analyzed the blasting construction technology in the construction of 12505 systems lane, formulate reasonable blasting protection measures, and strive to ensure safe and efficient roadway construction.
