May 12, 2014· Researchers at the NIOSH Mining Program have addressed the prevention of mining electrical injuries over the years with numerous studies focusing on power system design, engineering controls, work organization and procedures, protective equipment, and human factors. Much of this work utilized the NIOSH Mine Electrical Laboratory.
In the mining of most heavy minerals, the denser material would be the desired mineral and the rest would be discarded as floats (or tailings). There are some minerals, notably coal,that are lighter (lower in density) than the surrounding rock and in such instances the process of extraction would work in reverse, i.e. the coal would settle on
