A western Kentucky county has approved changes that will allow a new coal mine to be opened, but there are some restrictions once mining begins.

The Daviess County Fiscal court voted unanimously last night to uphold the rezoning of nearly 700 acres in the southern end of the county. But county officials also placed some limits on what type of equipment could be used at the mine and when the mine could operate.

The mine will be operated by Western Kentucky Minerals. The company officials estimate that about 2.1 million tons of coal are embedded in the land it wants to mine through surface or strip mining techniques.

An attorney representing homeowners who oppose the mine says no decision has been made whether to challenge the mine in court.
