New developments present ways to mitigate wild flyrock more effectively

Wild Flyrock has historically been a major problem in the mining industry, resulting in the injury of mineworkers who are caught in the blasting process. However, the reality is that the risk of flyrock can be greatly reduced by using new techniques and improving the attitude of those involved in the blasting process. Simon Tose, Group Consulting Mining Engineer at AEL, says blasting teams must follow the correct procedures in order to mitigate the possibility and severity of flyrock. “Any type of surface blasting breaks up rock, which is then propelled into the planned blast zone. Sometimes this rock is thrown further away than expected, which is referred to as wild flyrock and can result in damage to property as well as injuring people on the blast site and in nearby homes.”

The Evolution of Explosives from Fire Setting to Electronics provides big improvements to blasting

The evolution from the Bronze Age fire setting to modern day blasting with electronics has yielded major benefits for the mining industry. These include mitigation of damage to the environment, improving safety and enhancing efficiency of the blast, thereby also improving output and yield of the mining operations. This is according to Simon Tose, Group Consulting Mining Engineer at AEL Mining Services (AEL), who recently published the paper “From fire setting to electronics - A fun look at the evolution of explosives.” Tose says the main reason for the shift from the old dynamite cartridges to on site chemical energy coupled with electronic blasting is that it offers more control over the blast and the environment making the process significantly safer, more efficient and improving production. “Looking back to the methods applied through the ages from fire setting , where one relied on heating the rock, throwing water on it to rapidly cool and then breaking it down, to dynamite and safety fuse there was no real control over the blast.

Ensuring knowledge transfer at the WEETR

AEL’s annual WEETR (Workshop for Explosive Engineers and Technical Representatives) was hosted in June. The conference was tailored to increase technical product knowledge and equip the frontline with detailed information on specific AEL product offerings; best practice and how these offers differentiate AEL in the market. The conference affords AEL technical staff the opportunity to get updates Ensuring knowledge transfer at the WEETR (Workshop for Explosives Engineers and Technical Representatives) on the latest technical methods and projects, to be trained or refreshed on technical issues and to share their own work through presentations and informal discussion.
