PT Atlas Copco Nusantara in partnership for KPC
THE Kaltim Prima Coal (KPC) mine at
Sangatta is an 11-pit operation - so large that
it takes an hour just to travel from one side
of the property to the other. To meet the
monthly production goal of 3.3 million
tonnes, KPC contracted the drilling services
of Pama and Thiess. PT Atlas Copco
Nusantara’s satellite branch at Sangatta is a
complete partner with all three operating
companies, offering drill rig support and a
variety of service-related items.
The Sangatta service branch is like an ant
hill of activity. Although 90% of its work is
done outside the shop, service vehicles and
people move in and out of the property in a
continuous flow. Service operations are
active 24 hours a day, 7 days a week and 365
days a year, with 75 people manning the
office, customer shops, pits or the many fuel
depots and transfer locations.
The branch provides fire suppression system
installation, hose and fittings, lubrication
systems and consumable parts. It also services
and supports what could be seen as the largest
fuel management system in the world.
At KPC’s Sangatta mine 280 million
tonnes of overburden and 40 million tonnes
of coal are shifted annually, and that requires
a very large fleet. Atlas Copco’s technical
advisor Raymond Daniels says, “Every big
truck brand and large digger you can think
of is operating at KPC.”
KPC operates 30 of the largest diggers
made. For digger efficiency and to support
the optimal 12-metre bench height, 300-ton
trucks are the most efficient, and there are more
than 500 in operation. Add the truck fleets and
there are 800 trucks operating at KPC Sangatta
Mine. Combined, the vehicles consume more
than a million litres of fuel a week. Atlas Copco,
an authorized Banlaw dealer, manages the
sophisticated electronic fuel tracking system.
Thiess Indonesia Sangatta’s Drill and Blast Manager
Marradian Dwi shows the sticky overburden mine
that can cause complications with hole flushing.
PT Atlas Copco Nusantara’s responsibility
doesn’t end with fuel systems. It’s also charged
with the installation and maintenance of auto
lubrication, fire suppression systems and overall
fluid maintenance onsite.
Each pit presents variations in formation with
depths ranging from 40 to 70 metres of overburden
over the coal seam not lower than 120
metres below sea level. Marradian Dwi is
drill and blast manager for Thiess’ mining
operations and says two pits can be totally
different with up to 8 layers of coal in 5 to
30 metre seams at varying depths with 40 to
70 metres of overburden between layers.
One pit has a flat layer of coal 10 metres
thick with the bottom lying 120 metres
below sea level.
Due to the formation variations there is no
perfect bit but they’ve found the Atlas
Copco Secoroc EH42CAH 7 ⅞-inch bit and
Teamalloy 6.25 drill pipe to be the best for
the formation overall. They average 8000 to
11,000 metres per bit. Because Thiess is
paid by tonnage of overburden, it’s necessary
to have their operational equipment all
the time.
“We expect 98% utilization from our drill
rigs,” says Marradian Dwi. Their need for
dependable equipment brought them to PT
Atlas Copco Nusantara. In total they operate
seven drills. They use Atlas Copco’s DM45
SP and DML SP drill rigs for most drilling,
but they also have a multi-pass DM45. Each
drill averages 80 metres per hour, and each
is expected to drill 50,000 metres per month.
Marradian Dwi says, “For me, our decision
to use Atlas Copco comes down to less
maintenance required and greater availability.
That means greater operational availability
and greater parts availability.” As they
move forward he said he would also like to
utilize more training services. “My drillers
know how to drill but I want to make them better
and standardize best practices.”
Collaboration is proving the key to success at
Sangatta. By customizing its service offerings
to fit the needs of all operating companies, PT
Atlas Copco Nusantara is demonstrating how it
can be part of the large-scale operation’s winning
strategy.
