摘要
分析了大空孔螺旋掏槽爆破机理,并建立了首爆装药孔爆破力学模型,对其爆破参数的确定进行了探讨,将研究结果应用于广西华锡集团爆破掘进中,效果良好.
Based on the blasting mechanism of spiral cutting with big empty hole, a mechanic model of blasting in the first blast charges hole is estabhshed and the selection of blasting parameters is discussed. It proves that the blasting effect is very successful when the research results has been applied in the rock under- excavation blasting in HUAXI LTD,Guang Xi Province.
