The potential for mudrushes is a potential hazard that should be evaluated during cave mining studies. Mudrushes are a phenomenon that can have very different origins, but produce the same results: injury, loss of life, damage to property, excess dilution, production delays, or mine closure. Although mudrushes are more common in cave mines than other mines, any mining activity that enables the accumulation of fine particles and water is susceptible to mudflow. This paper describes the process developed by the authors during the past decade to evaluate the risk of mudrushes, specifically in caving and sublevel caving mines.
