Coulterville Quadrangle

Mining in the Coulterville Quadrangle

Mining has taken place almost continuously from before 1878 until present in the vicinity of the Coulterville Quadrangle. The oldest mines are directly contiguous to the town of Coulterville near the western edge of the quadrangle, and the more recent mines have advanced eastward from Randolph County. The Herrin Coal was mined, usually having a thickness over 6 feet. The roof material was often problematical, with pods or lenses of white top that came down readily, associated with slips and rolls that further contributed to poor roof conditions. Energy Shale was also present in some areas, a sandy gray shale that is also known as a roof that falls readily. In most areas, a competent limestone was present above the shale, and in some cases, was the immediate roof over the coal.
