Nov 20, 2008 Coal mines were usually located near urban centers for economic reasons, they required a larger work force to extract the coal and were generally owned by big business. Smoldering fires (some begun in the 1870s), subsidance of land and mine drainage are among the impacts that the extensive coal mining has left on southeasternCoal Mill Safety,VG: At best, coal mill safety is not well understood and, at worst, it is ignored. When it comes to coal mill systems, most cement plant operators just presume that the supplier of the equipment knows all of the standards and rules and is 100% capable of making a system that conforms to these and is therefore safe. However, this is not the case.
