Mine-wide Automatic Rock Dust System

MARS II is designed to distribute large quantities of rock dust underground, greatly simplifying the process and reducing the amount of man-power required to accomplish the task.

  • Mine-wide pipeline system with Transfer Stations in specific locations
  • Transfers bulk quantities of rock dust over distances up to 3,500 ft (1,000m)
  • Multiple lateral branches along the pipeline allow hose dusting at various intervals
  • Final Transfer Station can be used to fill portable rock dusters for additional and/or remote area coverage of the mine
  • Additional compressor stations enable the advancement of the system for the life of the mine


Permissible Underground Transfer Station
  • Fully automatic, semi-automatic, or manual underground distribution of rock dust
  • Single refill location at the surface
  • Results in considerable time and labor savings
  • Capabilities for large quantity handling, transport and storage
  • Flexible options for manual hose dusting along pipeline
  • Accessible underground storage for portable/mobile rock dusters
