It is examined a mine workings dumping increase dependence on the water inflow for deep anthracitic mines in zones near-by disjunctives. Due to the decline of strength of the watered roof rocks the coefficient of stability of the mine workings diminishes in nonlinear way down to 0,3–0,4. It is set the coefficient of the structural weakening exponential dependence on the distance to a tectonic violation, the time of exploitation of a mine working and amplitudes of disjunctives.
