I am trying to find information on the phenomena known as a ‘Mud Rush’.  
This occurs in the ore passes of underground mines where the material in 
the ore pass suddenly changes from a sold mass to a virtual liquid.  When 
the ore pass is opened the material flows out engulfing the people and 
equipment in the exit area.

I am researching this as I believe that the Particle Size Distribution and 
moisture levels play a significant role and urgently need to find a method 
of preventing any re- occurrence

Thank You
