GC: What kinds of producers are most proactive in coal mill safety?
The generation of nitrogen oxides within post-blast gases (commonly referred to as "fume") has become increasingly important for mines from a safety, productivity and regulatory standpoint, particularly those in populated areas. Coal mines are susceptible to fume when sleeping large blasts in soft, weathered and wet sedimentary rock.
Mill fires require immediate attention to prevent damage to the pulverizer and more damaging mill "puffs". Explosions in a pulverized coal system are normally called "puffs." A mill puff is an explosion in the mill system caused by an explosive combination of coal, air and temperature.
