Underground Explosives Charging Equipment

Safe and reliable charging system


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.

During the past four decades 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 explosive production and country 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.

Charging System

Today, all high-production underground operations use bulk explosives: ANFO, water gels or modern site sensitized emulsions.

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:

  • Be safe and reliable
  • Meet highest productivity and quality requirements of the industry

Normet has designed a complete range of underground explosive chargers around these needs.
Charmec’s are the result of:

  • Over 40 years of accumulated experience
  • Close partnership with tunnelling and mining customers across the globe.
  • Close partnership with global bulk explosive manufacturers

Normet has developed its modern emulsion 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.
