BEHIND THE SEAMS AT
BOGGABRI
A fleet of Cummins-powered dump
trucks and excavators is achieving
availability targets for mining
contractor Downer Mining at Boggabri
Coal in the Gunnedah Basin, NSW.
Cummins’ on-site support rates highly
at Boggabri with the mine operating
24/7 and set to produce more than
5.0 million tonnes of coal in 2014.
Downer Mining has been the mining
contractor at Boggabri Coal since
2006 when production began. The
mine is owned by Idemitsu Australia
Resources, a subsidiary of Japanese
petroleum company Idemitsu Kosan
Co., Ltd. Construction of the mine
began in January 2006 and the first
coal was produced in October.
Downer Mining’s current contract with
Idemitsu, which runs to December
2016, involves drilling and blasting, mine
planning, and loading and haulage.
Overburden haulage at Boggabri is
spearheaded by 17 Komatsu 930E trucks
with a 290-tonne payload capacity, and
the force behind their tractive effort is the
Cummins QSK60 engine rated at 2700 hp.
The reliability of the 930E trucks is
critical as they contribute significantly
to a total annual overburden and coal
movement of around 36 million BCMs.
The oldest 930Es had clocked up around
9,000 hours near the end of 2013,
with the youngest at 5000 hours.
