Geological Problems Reported
The roof of the Colchester Coal was about 18 feet of soapstone separated from the coal by 1 to 2 inches of dark bony shale. The seam had local dips or swales with over 5 feet of relief that made haulage difficult. The Colchester Coal also had lenses, balls and facings of pyrite, as well as calcite and gypsum fracture fillings.
