Observations from an Enhanced Gas Recovery Field Trial

"Without ventilation, a mine can't run, but with an efficient and optimised ventilation system you can save millions of dollars over the life of a mine."

Lionel Musson, Technical Services Superintendent, CBH RESOURCES – ENDEAVOR OPERATIONS

Mining ventilation, dust suppression and gas control are crucial to ensuring worker safety and equipment optimisation on site. Explosions, breakdowns and health problems can all increase if ventilation is not kept up to scratch. Furthermore, with inspectors and government setting such high standards, it is critical that your site continually reviews and updates ventilation strategies as the mine expands and airflow strategy becomes more complex.

This presentation from a recent Mining Ventilation conference describes an enhanced gas recovery field trial at a coal mine pre-drainage site in central Queensland. The speaker has had extensive experience in the field of gas drainage and gas management and will outline the results of the trial in relation to the outcomes sought. Russell Packham, Gas Drainage Contract Engineer and PhD Scholar with the UNIVERSITY OF NEW SOUTH WALES describes his experience with this trial in relation to:

  • Injecting nitrogen into a partially-drained coal seam
  • Stimulating improved methane recovery
  • Lowering residual gas contents
