The board has launched a search process to identify a replacement for Crutchfield.
"On behalf of our Board, I want to thank Kevin for his steadfast leadership and numerous contributions made toward the company's success during his many years with Contura and its predecessor companies," said Board Chairman, Neale Trangucci.
"Kevin's departure is not expected to change the company's business strategy, including the plan to return capital to shareholders. While Kevin will be missed, we have every confidence in the management team to execute on the solid operating foundation already in place as we work to identify the best individual to lead our company forward for years to come."
