Excavatability and the effect of weathering degree on the

Jun 01, 2016 · 1. Introduction. Excavatability is defined as the snapping off degree of rocks from whereabouts by excavating equipment and rippability is defined as the relative expression for rocks to be ripped and ruptured by a ripper-dozer (Ceylanoglu et al., 2007).Selection of the suitable excavation method and equipment in surface and underground excavations depends …

Excavatability Assessment of Rock Masses Using the

Kirsten (1982) proposed a system for the excavatability assessment in terms of rock mass characteristics, such as mass strength, block size, relative orientation of geological structure and joint walls strength. His classification system is based on engineering properties for the weakest soil to the hardest rock.

Prediction of the Rock Mass Diggability Index by Using

Rock mass classification systems are one of the most common ways of determining rock mass excavatability and related equipment assessment. However, the strength and weak points of such rating-based classifications have always been questionable. Such classification systems assign quantifiable values to predefined classified geotechnical parameters of rock mass.
