INFLUENCE OF SILICA FUME ON FIRE RESISTANCE
the risk of explosive spalling in case of high strength concrete with silica fume. Hertz [4] suggested to replace 10% of cement by silica fume as upper limit to avoid spalling.

1) Effects of blast pressure on the human body
explosions likely affect just one working section, whereas a large explosion could affect the entire mine. Usually, methane explosions at the face or outby range from small to medium explosions traveling hundreds of feet. If coal dust becomes involved, the explosion may become "large" and travel thousands of feet.

The "Explosion" in Blast Resistant Construction
01-10-2007The pressure decreases by a factor related to the cube of distance. For instance, a 25-lb charge exploding 30-ft away produces a pressure wave of 824 lbs/ sq ft (psf). Increase the distance to 50 ft and the pressure decreases to 365 psf. The blast shock wave creates two kinds of hazards. The pressure itself can destroy objects in its path.
