Mining

Mining is one of the larger contributors of inorganic dust in the environment.
Dust suppression systems and dust control systems on surface and
underground mines have been mandatory for decades.

Mine dust and gas management experts

CDC Dust Control is a mine dust suppression and mining dust control expert for all mining activities involving continuous miners, road headers, conveyor belt transfers and underground roads. We bring these expertise to gas control too, offering a niche dust and gas scrubbing solution for above- and below-ground mining applications.

Our company precedes 1995 with colliery dust control experience, but was only formerly launched that year in response to the impact and dangers of increased dust loads in mines. At the time, we worked in conjunction with the CSIR and DMR to develop a range of dust suppression systems in mines that would alleviate some of the dust loads. Each day since, our R&D specialists have engineered dust suppression solutions for niche applications in above and belowground mines, each designed to meet industry dust suppression requirements as they arise. Keeping abreast of evolving mining technology has helped us deliver mine gas and dust control solutions that exceed customer expectations.

Catering to both hard- and soft-rock mines

While our origins are in the coal mining sector, our specialised dust suppression equipment has evolved to meet the demands all hard rock and soft rock mining requirements. Our range of equipment for dust control in underground mines and surface mining can be used when mining:

Wet Fan Scrubber Units

High efficiency dust capturing with lower water and power requirements. Available in hydraulic or electric drive.

Spray Fan Systems

Available as directional and reverse-flush spray blocks, creating air flow that wets dust and lubricates equipment.

Transfer Point Assemblies

Ideal to dampen dust at conveyor transfer points and underground roads. Standalone or part of system.

Air Movers

Provides optimal air movement with minimal water and eliminates conveyor rollback.

Booster Pumps

2 variations that ensure optimum water flow and pressure for dust management equipment.

Water Filters

Manual, automatic & semi-automatic back-flush increases component protection.

Below ground and surface mining methods

Surface mining

Surface mining involves stripping dirt and vegetation, and then digging through layers of bedrock to reach ore deposits.

Methods of above-ground mining include:

  • Open pit mining:
    A large pit (hole) is dug which is wide enough so that as the pit deepens, mining machines and equipment are easily transported to and from the digging site.
  • Quarrying:
    Extremely similar to open pit mining, but sand, stone and clay rather than minerals are mined.
  • Strip mining:
    In this method, surface layers are stripped to expose either ore or ore seams hidden beneath the surface.
  • Mountain top removal:
    This involves removing the top of a mountain to access deep ore deposits.
  • Landfill mining:
    Not common in South Africa yet, this method is used to excavate and process landfills and is seen as a possible solution to deal with long-term methane emissions.

Underground mining

In underground mining, mine shafts (tunnels) are dug to deep depths beneath the earth’s surface to reach ore deeply buried ore deposits. The minerals mined are then brought to the surface where processing of the ore continues.

Methods of underground mining include:

  • Drift mining:
    This method makes use of horizonal access tunnels.
  • Slope mining:
    Diagonally sloping access shafts are used to approach the ore.
  • Shaft mining:
    Vertical access shafts are used to get to the ore.
  • Shrinkage stope mining:
    This technique involves mining upward to create a sloping underground room.
  • Long wall mining:
    This method involves grinding a long ore surface beneath the ground.
  • Room & pillar mining:
    Ore is removed from the room and pillars are left in place to support the roof.

We tailor all our equipment to suit clients’ exact specifications.
