Somerset County
A limestone mine you drive into
Two operations work near this borough. The Mine Safety and Health Administration records the Romesburg Quarry as an underground limestone operation with 13 people under Garrett Limestone Company, and underground is the unusual part — it is what makes the haulage here different.
The second is the Westgren Mine, working bituminous coal at surface with 7 people under Coal Loaders Inc. So one borough carries a surface coal mine and an underground limestone mine, and both sit about 2.7 miles from the borough centre.
Loading under a roof changes the day
That difference shows up in the equipment rather than in the rock. A room-and-pillar mine runs at a stable temperature and out of the weather, so the machines that work inside it are not taking the frost and rain that age a surface fleet. What comes out still has to meet the road at the portal, which makes a mine truck and a road truck two different vehicles here.
So the equipment turns over on two clocks. The Eichorn Mines about 12 miles south-west work limestone underground with 28 under Keystone Lime Company, and the Rockwood Quarry about 6 miles west works sandstone at surface with 8.
Four crossings in ten miles that will not take a load
Those crossings are the constraint the ceiling does not describe. Within 10 miles of the mines the FHWA National Bridge Inventory records 161 structures and four of them are coded below legal loads. The nearest is about 3 miles away, and the lowest rating among them will not take a commercial vehicle at all, empty or loaded.
So the county picture is heavier than the local one. Across Somerset County twenty-one of sixty-three county-maintained structures and thirteen of sixty township-maintained ones carry that coding — a third of the county stock and about a fifth of the township stock.
Tri-axle dumps and aggregate haulers off the stone, coal trucks and haulage bodies off the surface mine, flatbeds, day cabs and road tractors, rollbacks, service bodies and the pickups every small operation keeps beside its big truck.
Between the Westgren Mine here and the Cambria Fuel Plant about 10 miles north-east the two trades turn over separately, and a body set up for limestone is not what a coal operation is looking for.
- Tell us whether it has been on the road, because a machine that never left the workings is a different proposition to a registered truck.
- Can you collect from a pit or a portal?
A seam finishes or a contract ends, and the truck that served it has no obvious second home. At two and seven-person scale there is nothing to absorb it.
So it stands between the Rodamer Quarry about 11 miles south-west and the Coyote Mountain job about 14 miles south-east, on ground that has no further use for it.
