This interesting article from the NYT compares and contrasts the safety and business practices of the Upper Big Branch Mine with those of the nearby E3-1 Mine, run by TECO Coal Corporation. While the details on the culture and practice of mine safety are of technical interest, of greater interest to me is the contrast between business philosophies. One cut corners to maximize short term profits with tragic consequences. The other invested in training and safety to aim for long term success. Hat tip: Paul Blair.
