Mining of coal leads to coal dust, and flour mills likewise have large amounts of flour dust as a result of milling. A gigantic explosion of flour dust destroyed a mill in Minnesota on May 2, 1878, killing 14 workers at the Washburn A Mill and another four in adjacent buildings.
The Grover Shoe Factory disaster was an industrial explosion, building collapse and fire that killed 58 people and injured 150 when it leveled the R. B. Grover shoe factory in Brockton, Massachusetts on March 20, 1905. Following a boiler explosion, the four-story wooden building collapsed and the ruins burst into flames, incinerating workers trapped in the wreckage.

If velocities drop below, 3,000 fpm, fire or explosion in a coal pipe or pulverizer is possible if you don't pay attention to all of the coal particle velocities and sizing in each coal pipe.
Maximum Explosion Pressure at Constant Volume. Maximum explosion pressure (p max, MPa) is the maximum pressure, emergent by explosion of airborne powder in a closed vessel with initial pressure 101.325 kPa. These data are necessary for strength design of the equipment.
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.
