The mine had gas problems; 50 men died in a 1905 explosion, and in 1909, two explosions killed 29 men. The roof was a hard gray shale. Top coal was generally left to support and protect the roof. Some rolls were present in the seam. The seam had very frequent and prevalent flexures and swags that maintained a general southeast-northwest trending direction. This created serious haulage problems because of the steep grades. The top coal contained a considerable number of calcite seams. Pyrite balls were present but the distribution was very irregular. A squeeze occurred because of drawn pillars (1913), but generally the underclay floor did not heave.
