Lightning Protection Audit and Gas Drainage Risk Mitigation (Rio Tinto)

In two key projects, one of RioTinto’s mines was audited for all aspects of lightning protection and earthing.

The Brief

LPI was engaged to develop a solution to minimise the risk of methane ignition in the underground coal operations as a result of the installation of gas drainage wells across part of the mine site.

The Outcome

The audit was completed successfully, resulting in improvements to the existing protection scheme and a novel way of protecting gas drainage wells and avoiding underground sparking was developed. The latter method has been presented at mine safety and earthing conferences around Australia.
