Seal Breaching Operation in Quinland Coal Mine: A Case Study.

PB90265406

Publication Date	1988
Personal Author	Doyle-Coombs, D. M.; Hansford, R.
Page Count	30
Abstract	In late July 1985, air samples from a sealed portion of the Quinland coal mine in West Virginia showed the presence of carbon monoxide (CO). Mine Safety and Health Administration (MSHA) personnel concluded that a fire was burning behind the seals. Since an imminent danger existed, the mine operator was given a closure order. The gases behind the seals were monitored, and almost 2 million ft of carbon dioxide (CO) gas was pumped into the sealed area to stabilize the environment. Sixteen days after the closure order was issued, MSHA allowed the mine to return to production. Approximately 1 year later, mine management submitted a seal breaching request to MSHA in order to drive a set of entries to further develop the mine. The Bureau of Mines established a sampling strategy and monitored gases from behind the sealed area during the breaching operation until the atmosphere was safe. The report is an account of the seal breaching conducted by the mine, MSHA, and the Bureau.
