Some bad economic news for southwestern Indiana. Alliance Resource Partners has announced that its subsidiary Gibson County Coal LLC has issued Worker Adjustment and Retraining Notices to around 185 of its employees as the result of idling production at the Gibson North Mine. Company Chairman, CEO, and President Joesph Craft released a statement says the coal export markets have deteriorated over the last seven months and have contributed to an oversupplied domestic coal market. Until the conditions improve Craft says the response at the mine allows the company to adjust its volumes to meet current demand expectations at the lowest cost possible.
