World-class dragline performance has been credited for helping Stanmore Coal achieve strong results from its Isaac Plains complex near Moranbah last year.
The site’s Bucyrus Erie 1370W dragline – owned by Stanmore and operated by Golding Contractors – moved 16.843m bcm in 2019, a 19 per cent increase from 14.149m bcm in 2018.
During the last quarter of 2019, the dragline averaged over 50,000 bcm per day compared to the calendar year average of 46,600 bcm per day, after a new 49 cubic metre bucket was installed in August.
General manager operations Bernie O’Neill said the dragline’s performance at Isaac Plains East would put Stanmore and Golding among the best operators in the world.
World-class dragline performance
“For a BE1370-sized machine, this is world class performance and Isaac Plains would have been one of the best dragline operations in the world last year,” he said.
Isaac Plains East mine delivered significant improvements in total overburden removal last year with a 56 per cent increase in dragline system prime performance (dragline, blast cast and dozer push) from 9.862m bcm to 15.421m bcm.
ROM coal mined also increased by 46 per cent to 3.274m tonnes in 2019 and Stanmore’s CHPP processed 3.3 million tonnes of coal compared to 2 million
tonnes in 2018, an increase of 60 per cent.
The improvement in mining performance translated into strong growth in coal sales, from 1.6 million tonnes in 2018 to 2.6 million tonnes in 2019.
Stanmore also expanded its market footprint and is now selling to customers in Japan, Korea, China, Vietnam, India and Germany.
Mr O’Neill said Stanmore was looking to maintain this momentum in 2020.
“We made significant improvements over the 2019 calendar year in all key metrics and we expect to continue this in 2020,” he said.
“We commissioned a new CAT6060 excavator in November, which adds 11m bcm of overburden capacity to support performance improvement again this year.
“Our success over the past 12 months is a great credit to all involved including operators, supervisors, maintenance, drill/blast, tech services and support personnel.”
