The company's production expectations for the previous quarter announced in late July totalled 15.8 - 17.8 million tons, but actual production figures amounted to 14.5Mt.
Given the issues at the three mines, Consol has amended its fourth-quarter estimates from a range of 16.8 - 18.8Mt to 16.5 - 18.5Mt.
Assuming a November 15 re-start of its Buchanan operation in Virginia following ventilation issues that closed it earlier this year, Consol provided new guidance on its anticipated total for the year of 65.2 - 67.2Mt rather than 66.9 - 70.9Mt.
Earlier this week, the producer said it had submitted documentation and plans to reopen Buchanan, citing an overall and continued improvement in gas levels underground.
