Abstract
The determinants are found and the matrix is developed for rate of wear of heading machine cutting tool. Influence of rock strength on active life of heading machines is assessed. The authors describe field studies into the nature and rate of wear of cutters. The design of multiuse tangential revolving cutter of prolonged operating life is engineered and trialed. It is proposed to enhance rock cutting efficiency using a tool with a cutting wheel.
