Normets’ Charmec systems are built to improve safety and productivity in underground blasting and contribute to high quality and cost-effective bulk explosive charging. They also offer a consistently high resale value with low lifetime costs.
Hundreds of mobile Charmecs have already been delivered to hard rock mines and civil tunnelling projects worldwide.
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:
Today, all high-production underground operations use bulk explosives: ANFO, emulsions or water gels.
To maximise the benefits of bulk materials, the charging processes must be properly mechanised.
Whether the equipment is used for face charging with horizontal holes or for production charging with up-hand and/or down hand holes they have to:
Normet has designed a complete range of underground explosive chargers around these needs.
Charmec’s are the result of:
Normet has developed its modern emulsion and water gel charging concepts in close cooperation with explosives manufacturers as authorities usually regard the units where the explosive is sensitised on the charging unit as explosive factories.
