摘要
针对ER9350液压铲对货源提出的要求,通过对爆破设计参数的优化,采用大孔距小抵抗线爆破技术反复进行现场试验,达到了改善其货源条件的目的,使其可以高效安全的进行采掘。
Aiming at the requirements of ER9350 hydraulic shovel for the supply sources, the blasting technique has been tested repeatedly with wide spacing and small burden on site to reach the goal of improving the supply source conditions so that high efficiency and safe excavation operation can be achieved.
