I am working as a coal geologist for over 6 years and often plan and manage exploration program for coal. Here are some snaps where I worked with some of the most experienced drillers from LJ Huges and Sons. They had a nice Atlas Copco Drill. We drilled couple of hole, one of then nearly 900 feet deep. Enjoy some of the snaps I took at the site.
