  • 3D Blast Movement Monitoring BMT

    Controlling ore loss and dilution is critical for all mining operations. Getting it wrong can result in tens of millions of dollars of lost revenue per year. You want the ore that you ve spent money defining and grade-controlling to end up in the mill. But ore movement occurs in all blasts. And failing to account for movement post-blast means that ore is sent to the waste pile and waste to the mill.

  • Drilling and Blasting Technical Aspects of Mining

    Most blasting in mines involves charging explosives into holes drilled in rock. The entrance or mouth of a drill hole is called the collar and the end is the toe. Drilling is still carried out in some cases in the ASM sector by hand using a hammer and chisel. This is obviously tedious and slow especially in hard-rock mining conditions.
