Consol Energy is blaming lost production from its Buchanan Mine Number One in Virginia for a 94 percent decline in its fourth-quarter profit. The Pittsburgh-based coal company said it earned 6.8 million dollars in the three months ended December 31st. Consol earned 115.3 million dollars in fourth-quarter 2006. Total revenue and other income in the quarter fell to 918.6 million dollars from 953.7 million dollars in 2006. The Buchanan mine near Mavisdale, Virginia, has been idled since a roof collapse in July. Consol says it took about 31 million dollars in charges related to Buchanan, after accounting for an initial insurance recovery of 25 million dollars. Consol is also considering ways to increase production due to high demand for coal exports.
