The characteristics of strength of rock mass for wear of rippertipare expressed precisely as "Index of rock mass strength for wear".The wear amount and the wear length of pointed end of tip increaseapproximately with linear relationship to the ripping operation time,and each slope varies respectively according to the index of rock mass.For the rock mass which both index of rock mass strength for wear andabrasive strength of rock are small, the wear of side parts of tip progressesmore rapidly rather than that of pointed end of tip. On theother hand, for the rock mass which both index of rock mass strengthfor wear and abrasive strength of rock are large, the wear of pointedend of tip progresses more rapidly rather than that of side parts oftip.
