Abstract. The key objective of this paper is the presentation of a new risk assessment tool for underground coal mines based on a simplified semi-quantitative estimation and assessment method. In order to determine the risk of explosion of any work process or activity in underground coal mines it is necessary to assess the risk.

Pulverizers / Mills. Reliable coal pulverizer performance is essential for sustained full-load operation of today's power plants. An effective pulverizer must be capable of handling a wide variety of coals and accommodating load swings in utility boilers as large as 1,300 MW. B&W's pulverizers, found at power stations throughout the world.

Power generation typically involves direct firing systems. There is an air swept mill with direct pneumatic conveying through to the burners. The risk of explosions is more or less reduced to an explosion inside the mill, which therefore needs to be explosion, pressure, and shock-resistant. NFPA requires coal mills to be good for 50 PSI.
