ALLIANCE RESOURCE PARTNERS, L.P.
Announces Resumption of Production Operations at Dotiki Mine
TULSA, OKLAHOMA, May 4, 2010 – Alliance Resource Partners, L.P. (NASDAQ: ARLP) today announced that, following a series of rigorous safety inspections and reviews, officials from the Mine Safety and Health Administration (MSHA) and the Kentucky Office of Mine Safety and Licensing (OMSL), along with employees of ARLP’s subsidiary, Webster County Coal, LLC determined that the Dotiki mine could safely resume operations and production began early this morning. Operations had been idled since a roof fall accident that occurred at approximately 10:00 pm on Wednesday, April 28, 2010. “Our internal investigation to date indicates that the roof fall was an unpredictable accident involving unforeseeable geological conditions,” said Charlie Wesley, Executive Vice President of Webster County Coal and a former Dotiki miner. “We will continue to cooperate fully with the MSHA and OMSL as they complete their investigations.”
The accident claimed the lives of two Dotiki miners, Justin Travis and Michael Carter. “We ask that you join us as we continue to pray for, think about, and extend support to the families of these dedicated men,” said Wesley. “We also ask that you keep our entire Dotiki family in your thoughts and prayers as we have each felt the impact of this terrible tragedy.”
“As we mourn the loss of these two brave men,” Wesley stated, “we remain proud of the Dotiki miners and our safety record. This tragic accident is the only event of its kind in our forty-four years of operating at Dotiki. Our lost-time-injury rate for the past five years is 48% below the industry average.”
Dotiki, the largest mine in Kentucky and one of the largest underground mines in the United States, employs more than 400 miners and has almost 600 miles of ventilated underground tunnel – longer than the distance from the Dotiki mine near Madisonville, Kentucky to Washington, D.C.
Commenting on the mine’s compliance record Wesley stated, “It is unfortunate that some have misunderstood citation statistics, ignoring varying mine sizes and the regulatory structure under which we operate. Since the pure number of citations greatly depends on the size of the mine, a much more relevant measure is the number of citations per inspection day. Dotiki’s citation rate per inspection day is 43% below the industry average. Perhaps more importantly, in 2009 and 2010, Dotiki has not had a single unwarrantable failure citation or, prior to this accident, been closed a single time by either federal or Kentucky inspectors.” Wesley concluded, “Our culture of safety is strong. We have families that have sent three generations to work in the Dotiki mine. I know these miners care, they represent themselves and safety is their top priority.”
