对露天矿台阶深孔爆破效果的评价方法,概括起来有以下几种: 1.用电铲的铲装性能来衡量爆破效果 澳大利亚的Shirley Williamson等人提出了用电铲的某些性能来衡量爆破效果的优劣。电铲的这些性能通过监测直流马达和引起生产变化的继电器以及爆堆的可控指标来评价的。用磁带记录仪记录电铲每一工作循环的各个参数所对应的马达电压信号,并用计算机进行处理,再按经验确定可控制指标值。这些指标包括块度分布、膨胀系数和爆堆形态。
To summarize the evaluation methods of deep-hole blasting effect of open-pit mines, the following methods can be summarized: 1. Shoveling performance of shovels to measure blasting effect In Australia, Shirley Williamson et al. Proposed to measure blasting with certain properties of shovels The pros and cons of the effect. These features of the shovel are evaluated by monitoring the DC motor and the relays that cause the change in production, as well as the controllable indicators of the blast. Using a tape recorder to record the motor voltage signal corresponding to each parameter of each working cycle of the shovel and processing it by a computer, and then the value of the index can be controlled according to experience. These indicators include the degree of block distribution, expansion coefficient and explosive stack morphology.
