By use of several digging principles, such devices as scrapers, clamshells, power shovel loaders, etc., have been perfected. The net results have been an almost complete elimination of hand mucking, an increase of loading speed, and a reduction of sinking costs. Moreover, the elimination of hand mucking has had a favorable psychological effect on the crew, as well as saving physical effort for the other phases of the shaft-sinking cycle.
