Geological Problems Reported
Very little timbering was needed for the gray shale roof. It arched well and the gob packs behind the advancing longwall provided adequate support. Black shale made up the roof locally, and ranged from 1 to 3 feet thick. This black shale came down easily and contained concretions. The coal was thinner under the black shale. The roof was poor near slips and rolls. The coal contained pyrite bands and balls as well as sheets of calcite and pyrite along cleavage planes. A persistent band of pyrite balls occurred 21 inches from the top of the seam.
