Method for solving underflow discharge of deep cone thickener

The invention discloses a method for solving underflow discharge of a deep cone thickener, and relates to the field of mine tailing disposal. The method comprises the following steps that a feeding mechanism feeds materials into a deep cone thickener; a feeding coefficient is obtained; if the feeding coefficient exceeds/is lower than a preset coefficient threshold range, an early warning signal is generated; a control center receives the early warning signal and allocates a corresponding manager to adjust the feeding mechanism, and the feeding coefficient is adjusted to be within the preset coefficient threshold range, so that the situation that too high material discharging speed and too many materials are accumulated in a deep cone pit, a cone pit is blocked, and the materials are hardened is avoided, and it is guaranteed that the equipment can normally discharge underflow; when the pressure at the bottom of the deep cone thickener exceeds a preset pressure value, the control center controls the feeding mec
