Highland Mine complex near Henderson is being idled while repairs are made to a preparation plant damaged by a structural failure last week.
Patriot Coal Corp. announced Monday that the complex was stopping all coal production and expects full production to be restored by June 30.
Patriot said in a statement that limited production may resume earlier when sufficient repairs have been made to the preparation plant to resume partial coal processing operations.
More than 500 people work at the complex at full operation. It ships approximately 3.8 million tons of coal annually.
A portion of the preparation plant was damaged in the failure on Tuesday.
Patriot Coal produces and markets coal in the eastern U.S. and has 10 active mining complexes in Appalachia and the Illinois Basin.
