FIELD: mining.
SUBSTANCE: according to the offered solution in addition the saturation voltage of the selection circuit is determined, the level of input signal of the selection circuit is determined and the identical values of coefficient of re-ejection and amplification in pairs are selected. Then the value of amplification coefficient k is determined, and the saturation voltage of amplifiers Usat-a in pairs is selected from the inequation Usat-a>Usat-sc.
EFFECT: increase of reliability of monitoring of change of physical-mechanical state of mass of rocks at selection of forecasting characteristics.
