Mudrush prevention
According to SRK, Mudrush, mudflow, or mudpush are the most common terms describing the uncontrolled ingress of an assorted mixture of water and solids.
“Mudrush is the underground equivalent of surface debris flow. It can have different origins but produce the same results: injury, loss of life, damage to property, excess dilution, and production delays, or — in extreme cases – mine closure. Mudrush dynamics in underground mining are especially complex due to confinement and stress within the muckpile”
