Hauling the CoalIn addition to its new

Caterpillar 6015B hydraulicmining shovel, LehighAnthracite LP also pur-chased two Caterpillar 777Frigid frame haul trucks. The777Fs were needed to helpkeep up with productionsince the new shovel waspurchased. LehighAnthracite LP spent quitesome time searching for twoquality haul trucks to add tothe fleet. (Lehigh has a fleetof multiple Caterpillar 777s,775s 773s, Hitachi 1700-3sand miscellaneous Euclids.)

The 777Fs are 2008 models and were pur-chased from Bill Miller Equipment SalesInc., which is located in Eckhart Mines, Md. Lehigh has dealt with Bill Miller in the

past and has built a great relationship withthe company. Miller’s technicians rebuiltand repainted these two 777Fs in house.Once they were delivered to Lehigh’s minesite, Miller’s technicians assembled and test-ed them, making any necessary adjustmentsand fixes. The cab and chassis were deliv-ered separately from the dump bodiesbecause the latter required a super load per-mit to be moved. The 777F is powered byCat C32 Acert 12-cylinder engine, whichhas a net horsepower rating of 939 hp. Thetruck has a top speed of 40 mph whenloaded. The 777Fs have a 100-ton loadcapacity and weigh in around 180 tons whenloaded. These two trucks are usuallyassigned to moving raw coal from the minesite to the stockpile/processing area.

Supplying the Coal Needs of the WorldLehigh Anthracite Coal produces a wide array of coal products from its mines in Tamaqua and Nesquehoning, Pa. These finished products

include:• Egg/Stove, which is 3 ¼-in. x 1 9/16 in. This is used as a carbon additive in electric arc furnaces (EAF), as well as a heat source in the sugar

beet process, and as a radiant heat source in pizza ovens;• Nut, which is 1 9/16-in. x 13/16-in. This also is used in EAFs and is a very popular size for home heating;• Pea, which is 13/16-in. x 9/16-in. This is another size popular for use in EAFs and sometimes home heating;• Buck, which is 9/16-in. x 7/16-in. This particular size is ground into a paste that is then made into high voltage electrodes for EAFs. This also is

a source of heat for large greenhouses; • Rice, which is 7/16-in. x 3/16-in. and is very popular for home heating;• Barley, which is 3/16-in. x 3/32-in. This is used in carbon injection in EAFs to create an insulating blanket on top of the liquid metal in a kettle; • #4, which is 3/32-in. x 3/64-in. This is used as a filter media (along with sand) in municipal water treatment plants; and• #5, which is 1 mm x 100 mesh. This also is used in carbon injection for EAF, water filtration and as an ingredient in charcoal briquettes.
