Drillability determination Then, the best parameters of rock based on determination of coefficient will be selected to compute rock drillability. To define coefficients of this model, multiple non-linear regression will be best possible determination of the drillability of intact rock can hence only be achieved by evaluating the.

The mineral composition of the rocks was estimated using modal analysis in accordance with procedure suggested by ISRM. It was stated that modal analysis is a valuable tool in the precise determination of the proportion of minerals present in fine to medium grained rocks (gneiss and limestone).
Characterizing the abrasiveness of soil/rock and the allowable wear of hard-facing products in various conditions is a critical factor in selection of the best material for certain applications related to drilling and excavation in mining and construction industries.
