The roof was generally a white shale that did not hold up well. In some cases, these developed into sinkholes that opened up to the surface. Wherever possible, 18 inches of top coal was left to support the gray shale roof. In some areas, the roof was black shale, and this held up well. Rolls were present, generally in the northwest part of the mine where they were numerous. These rolls sometimes cut down into the coal so that only 2 feet of coal remained. Some of these areas were designated on the source map as “very bad coal”.
