Efficient ventilation systems in underground mines are paramount for regulating airflow, the amount and quality of air, as well as returning contaminants (gases, dust and heat) to the surface. Without proper control, extraction or dilution of contaminants, poor ventilation conditions can jeopardise the occupational health and safety of underground mine workers, resulting in potential fatalities. Generally made up of two ventilation systems, the primary one controls the total air volume flow through an underground mine, drawn in from the surface, and is also the exhaust circuit for the mine’s ventilation, or return airways (RAW) The secondary ventilation system refers to the provision of ventilation to development ends, stopes and services facilities which constitute secondary circuits tapped off the primary circuit...

IT’S essential for underground mining that adequate ventilation systems are in place. The Ventchoke system is a low cost mechanism that can control  secondary ventilation circuits underground with any vent duct installation. After 30  years working underground, UVS chief executive officer Darren Gilbertson took matters into his own hands to improve the ventilation issues he had experienced, and developed Ventchoke. Designed and innovated over four years, it has been through strict condition testing on-site, including 13 months initial research and development on a Kalgoorlie underground mine site. The Ventchoke offers a solution to the problem of ongoing repairs by eliminating costs on maintenance. It will work continually without attention for a minimum of 12 months, offering massive saving to mines...
