Situation

Since 1983, Peabody Energy has had a successful coal min-
ing presence in Wyoming’s Powder River Basin. Originally two
separate mines, the North Antelope and Rochelle operations
merged in 1999 to become one of America’s largest coal mines.
Located 65 miles south of Gillette, WY, the North Antelope
Rochelle Mine (NARM) is located in the top coal-producing
region in the world.

In 2010, NARM shipped a record 105.8 million tons of com-
pliance coal. Nearly 2.5 billion tons of recoverable low-sulfur
coal remain in an area covering almost 28,000 acres (11.331
hectares). Coal is moved at NARM by the truck and shovel
method. Considering the annual shipment levels and the

recoverable tonnage available, a considerable fleet of equip-
ment is necessary to maintain current production.

Solution

In order to achieve these increased productivity goals,

Peabody chose to build a fleet of Liebherr T 282 C mining
trucks at NARM. The T 282 C combines a high-horsepower
diesel engine with an efficient Litronic Plus AC drive sys-
tem to maximize productivity and minimize fuel consump-
tion. Having the largest payload to empty vehicle weight in its
class, the T 282 C hauls more for less to achieve maximum
profitability.

Discussions started between Peabody and Liebherr in 2008.
Peabody Energy began replacing their smaller mining trucks
with T 282 C models in 2010. As of November of that year,
14 trucks were sent to NARM, a number that was doubled four
months later. At present, over 40 Liebherr T 282 C mining trucks
are operating in the Powder River Basin.

Assignment Report

NARM has coal seams in this area ranging from 60 to 80
feet thick (18 to 24 meters) in reserve areas 100-400 feet

below the surface (30-122 meters). Average high tem-
perature is 85º F (29º C), and average low temperature is

10º F (-12º C), but ambient temperatures can range anywhere
from -40º F (-40º C) to 110º F (43º C). As Peabody sought to
maintain and increase production at NARM, a fleet of mining
trucks capable of high-level productivity in extreme condi-
tions and adaptable to various surfaces and applications was
needed to meet these goals. This challenging mining envi-
ronment demanded equipment that not only delivered the

performance necessary to maintain and increase production,
but that could also perform efficiently under such conditions.

With such a high volume of coal being extracted and moved
through the mine, Peabody’s goal required an extensive, cost-
effective fleet of mining trucks. To make this increased produc-
tion profitable, this fleet needed to be fuel-efficient in order to
reduce costs, and to have the versatility to haul coal and waste.

Performance

With its versatility to consistently haul 400-ton payloads of
coal or overburden and its high fuel efficiency, the T 282 C has
proven its productivity while maintaining a low cost per ton.
For these reasons, the Liebherr T 282 C will continue be an inte-
gral part of Peabody Energy’s increased production goal at NARM.
