As far as the surface soil mining is concerned at the surface coalmines, there are usually large quantities of the excavated material comparing to the quantities of mineral resources, which causes significant exploitation costs.The important fact here is the number of delays because of the frazzle of the cutting element (tooth) of the dredge shovel. The very fact proves that the previous approaches in solving this issue did not meet the basic efficiency requirements of the dredge exploitation. In this study, only some of the parameters that affect the cutting body strength have been discussed.
