The 1909 Coal Report stated that the mine made considerable gas. Two explosions, one in 1909 and one in 1917, killed a total of 6 men. A southeast-northwest trending igneous dike was cut through the coal 800 feet east of the shaft. A northwest-southeast trending fault, shown on the source map, halted eastward expansion. The roof was 10 feet of black shale that contained numerous concretions (some ranging up to 4 feet in diameter). In some limited areas, the roof was lenticular gray shale pods up to 2 feet thick. The boundary between the coal and the roof was irregular. The coal was very hard and this made for difficulties in shooting off the solid. Concretions were also present in the seam, and the floor contained pyrite concretions. The floor tended to heave when wet.
