Property "Seam" (as page type) with input value "Danville A microfilm map (document 351372, reel 03135, frame 410) shows room and pillar mining near the shaft from March 1933 to May 1934. The seam is not designated on the map source. Because the map shows the workings in the last two years of operation, the room and pillar mining may actually be mining of the large block of unmined coal surrounding the shaft bottom in the longwall part of the mine (in the lowest seam, Colchester Coal). However, the configuration shown does not precisely match the un-mined block. The map may show operations in what was termed the “1st Vein”, or Danville Coal. Because of the uncertainty, the accompanying map for the Danville Coal may not accurately depict the mining that took place." contains invalid characters or is incomplete and therefore can cause unexpected results during a query or annotation process.
Property "Seam" (as page type) with input value "Assumption At times an upper vein was mined. The interval between the two seams varied from 2 to 25 feet. The upper seam was often too thin to mine." contains invalid characters or is incomplete and therefore can cause unexpected results during a query or annotation process.
