Abstract

In the process of working downhole, the load of the bailer chain drive motors (main drive) of multi-digger excavators and dredges, all other things being equal, is continuously changing. Fluctuations (called natural fluctuations) of the motor load of this drive are the result of variability of the number of scoops in contact with the mined rock and changes in the total resistance to digging along the length of the face. The frequency f of natural load fluctuations is determined by the speed v and the pitch t of the scoop chain ...
