This mine had difficulties with gas; one man was killed in a 1913 explosion, and nine were killed by a 1916 explosion. The roof was gray shale, reportedly 107 feet thick, which fell readily after exposure. Generally 14 to 30 inches of top coal was left to support the roof at the active face; this top coal and some of the pillars were mined on retreat. The seam contained pyrite and calcite lenses, but less than was common in the district. The underclay heaved when wet. A squeeze was noted in SE 19-T6S-R2E.
