The loaders and trucks normally stay underground in the mine: there even is a large underground workshop where maintenance and repairs on these are carried out. For some reason these two got to see the daylight today. When you imagine that the tires on the loader are about as tall as I am it can be quite scary when these trucks come flying at you on the steep and narrow underground roads

Drill rod Mikado... A large part of the rods that we were using appeared to be so rusted on the inside that the inner tube became stuck on its way up and down. This resulted in numerous wireline cable breaks (the fact that the cable had been rusting somewhere outside for the last 10 years did not help here) and once we drilled without the inner tube assembly in place. This means that you drill the core but that it does not go into the core tube but rumbles around in the corebarrel instead. Eventually, after replacing all the rusted rods, we succeeded in retreiving 8 of the 10 feet of this core.
Monday morning 06:30 in Pearisburg: an absolutely stunning sunrise seen from our hotel. Pearisburg lies in the middle of the Appalachian mountains and in fact the Appalachian trail (some 1500 miles long or more) passes right through it. Unfortunately I have not had the time yet to wander around a bit... maybe later today?
Saturday and Sunday last week we spent in the workshop making one working LM37 drill from two pieces of LM37 junk that have been sitting outside for years and years. And yes, bolts and other parts tend to be rusted into place then... One big cheer for the penetrating oil and the anti-seize is definately justified here
