Historical documents suggest this coal seam was mined for steam coal for river boats on the adjacent Ohio River. Four exploratory borings will also be advanced in the general area to determine if mine voids exist and if there has been any collapse in the mine voids if they do exist. Percussion drilling and air- hammer drills are not allowed on this project.

AML employees will utilize a downhole camera to verify current c
