Mining Media International has opened registration for the Longwall USA 2015 International Conference & Exhibition, which will take place June 16-18, at the David L. Lawrence Convention Center in downtown Pittsburgh.

With an expected turnout of 2,000 or more, Longwall USA will be the largest technical conference geared toward underground coal mining this year. The program focuses specifically on longwall mining — the safest, most productive form of underground coal mining. Professional development hours are available for mining engineers.
