Strata MARS II System

The Strata Mine-wide Automatic Rockdust (Stonedust) System (MARS) is an automated storage and dispersal system for the pneumatic transfer of rock (stone) dust in underground coal mines.

AUTOMATED STORAGE AND DISPERSAL SYSTEM

The system provides the capability to automatically transfer bulk quantities of rock (stone) dust from surface storage silos into a single, or multiple underground storage pods. A permanently installed underground pipe-range of inline slave pods can be expanded as the mine advances, carrying supplies mine-wide and inbye.  

  • Mine-wide pipeline system with Transfer Stations/Slave pods in specific locations
  • Inline slave pods can be placed at distances up to 3,500ft (1000m) apart
  • Each can be used for manual hose dusting directly from the pod
  • Multiple lateral branches along the pipeline allow hose dusting at various intervals
  • Final slave pod inline can be used as a refill station for mobile dusters such as trailer-mounted pod dusters, trickle dusters and flinger dusters
  • Additional compressor stations enable the advancement of the system for the life of the mine
