Charging

The no.1 charging system

Successful drill and blast excavation in underground mines and tunnels ensures professional, productive and safe charging and blasting. While rock and groundwater conditions and local legislation dictate the types of explosives that can be used, all drilling and blasting operations have one thing in common: no method of charging will make up for poor drilling, but good quality drilling can be ruined by inadequate blast design and poor charging quality.

Today, all high production underground operations use bulk explosives: ANFO, emulsions or water gels. To maximize the benefits of bulk materials, the charging processes must be properly mechanized. The equipment has to be safe and reliable, while meeting the highest possible productivity and quality requirements of the industry – whether for face charging with horizontal holes or for production charging with up-hand and/or down-hand holes.
