Southern Indiana Drilling works for nine steady quarry clients in a 60-mile radius of its Scottsburg, Ind., headquarters.
Don Powell of Southern Indiana Drilling works an
area he refers to as a driller’s paradise. He and his six drillers work for
nine steady quarry clients in a 60-mile radius of their Scottsburg, Ind.,
headquarters.
Vice president of Atlas Copco independent distributors, Tom Borer, has known
Powell for years. He says the longevity of Powell’s client relationships is not
just about regional opportunity, attributing Powell’s success to his expertise
and reliability. “He’s one of the best drillers I’ve ever known,” Borer says,
adding that Powell does whatever it takes to get a job done. “When that has
meant staying 20 hours on a job, Powell has done it. His clients know he will
not let them down.”
His equipment has the same reputation. Borer relates: “It’s ridiculous how much
life Don gets from his equipment – rigs, bits, everything.” He still owns and
operates every rig he ever purchased since 1994, starting with his first
Ingersoll-Rand T4. He remained loyal to the brand through its 2004 acquisition
by Atlas Copco. His most-recent purchase is an Atlas Copco ROC L8. Powell works
with Atlas Copco distributor Brandeis Machinery and Supply, and counts on his
sales representative, Doug Flynn, to help him with what he
needs.
Borer gestures toward two Ingersoll-Rand T4BH rigs receiving preventive
maintenance this day from Powell’s crew on an asphalt pad that the Sellersburg
Stone quarry made for them. The first, a 1994, has more than 20,000 hours on
it. Neither it nor its sister rig, the 1990 model next to it, have been
refurbished. “I really should take them in for refurbishing,” Powell says,
explaining that he’s just too busy. He can’t take these rigs out of production.
Nor does it seem all that necessary.
Borer credits Powell for keeping his machines in shape: “They are running
great. He keeps them in good shape.”
When asked just how hard these rigs work for him, Powell answers, “I put 65,000
feet on one in one month – that was a really good month.” It was during a
record year for the quarry, which yielded nearly 3 million tons of aggregate.
This year, it will make 1.5 million tons.
Powell owns seven rigs – three T4 rigs, a DM-45, an ECM 720, an ECM 690 and a
brand-new Atlas Copco ROC L8. All of his rigs except for the DM-45 are on the
job every day. He used to do stripping work with the DM-45, which is just too
big for the quarry bench work he does today. He keeps it on hand in case a quarry
should want to expand and then need a great deal of overburden
removed.
When Powell bought his most recent acquisition – the ROC L8 – it wasn’t a
replacement rig or an upgrade; it was an addition. The new L8 looks as though
it will continue the legacy of its processors. Only six months on the job, it
already has more than 75,000 drill feet on it.
In this quarry, the L8 is used in place of a T4. The L8’s hefty compressor
delivers 865 cfm at 350 psi, which is ample enough to keep pace with a T4 on
the 40-foot limestone benches. Rate of penetration here between the two is
comparable in the quarry’s level, good-quality limestone. The two rigs will
average 31⁄2 feet a minute. The T4 trips a little faster because it has fewer
sections to makeup and breakout for the same distance – just three rods to the
L8’s four or five. However, the L8 shines in this quarry work because it offers
rapid setup on these benches. It does not need to lower its boom to move about
from hole to hole or pattern to pattern, and the boom itself can move forward,
backward and to the side for lining up quickly on pattern
targets.
The L8’s operator never leaves the cab to switch from driver to operator, never
even changes position, in fact. Its dual oscillating tracks can handle rougher
terrain and drilling attitudes. While he has plenty of utility for his T4s,
Powell says the L8 is more productive at less cost in this quarry application.
Unless you are the L8’s assigned driller, Chris Greenwood, you won’t ever get
the opportunity to run Southern Indiana Drilling’s L8. And if you are thinking
of waiting for it to break down to get a deal on it, good luck.
