【 摘 要 】

In the paper the directions of a significant increase in effectiveness of mine rocks destruction by tools equipped with super hard inserts from composite materials are reviewed and justified. Designs of mining drill bits with the cutting insert in the form of elliptical Cassinian oval and the asymmetric ring cleaves are suggested. Versions of laboratory stand constructions are developed in order to determine the power consumption of rock destruction.
