    In areas where coal mining has not been previously practiced, the search process should result in obtaining coal samples that give reasonable evidence of the existence of a coal seam. In fact, it is not uncommon to drill down to the top of the coal seam by rotary drilling and then replace the drill tools for core drilling.
