摘要
将保利久联高精度JR数码电子雷管用于贵州省晴隆县某露天矿山开采试验,并与塑料导爆管雷管的爆破振动和爆破块度进行对比分析,结果表明,在露天矿爆破中采用高精度JR数码电子雷管比塑料导爆管雷管爆破质点振动速度峰值降低了28.76%,振动主频提升了47.30%;爆破块度方面0~20cm增加了17.44%、20~40cm降低了7.23%、40~60cm降低14.97%、60~80cm降低19.02%。采用JR数码电子雷管能有效减小爆破振动危害,降低了爆破大块率,提高现场挖掘和装载效率,减少二次破碎,保证了工期,进而使得整体施工成本得以降低,确保了整体的经济效益。
Comparative analysis of blasting vibration and blasting block for the Polylong joint high precision JR digital electronic detonator and the plastic nonel detonator used in the open pit mining tests in Qinglong County,Guizhou province showed the peak value of blasting particle vibration velocity down 28.76%,vibration frequency up 47.30%,blasting block 20~40cm up17.44% and blasting blocks 20~40cm,40~60cm and 60~80cm down 7.23%,14.97%and 19.02%respectively using the high precision JR digital electronic detonator in open pit mine blasting compared with the plastic nonel detonator.The JR digital electronic detonator can effectively reduce blasting vibration damage and rate of blasting chunk,increase efficiencies of the site excavation and loading and reduce secondary crushing to ensure the project completion on schedule,thereby lowering the overall construction costs and securing the overall economic benefits.
