Anglo American (LON: AAL) is ramping up work to resume longwall mining at its Grosvenor coal mine in Queensland, Australia, almost 18 months after a methane explosion that seriously injured five workers.
The company, which was granted permission to bring back workers to the mine in April to conduct safety and compliance inspections, said it has been implementing since a staged resumption of operations since.
Delivering its third quarter results, Anglo noted it aimed to resume operations by the end of the year, subject to approval.
Since the accident, the company has completed works to permanently seal the impacted area of the mine with five large concrete seals.
It has also installed additional gas monitoring infrastructure and completed a highly rigorous risk assessment process, drawing on both internal and external experts.
Anglo American’s export metallurgical coal production dropped 11% to 4.3 million tonnes for the September quarter, as operations at its Moranbah North coal mine in the Queensland were impacted by challenging geological conditions for most of the quarter.
Grosvenor, located about 190km south-west of Mackay, produced its first coal in 2016 and has an anticipated mine life of over 30 years.
