About this document
RMR Classification and Rating Guide by Aida Rafrin is a document available to read on EtoBox.
This document provides a classification system for rock mass that considers various parameters like uniaxial compressive strength, drill core quality, spacing of discontinuities, condition of discontinuities, groundwater conditions, and effect of discontinuity orientation. These parameters are assigned ratings which are then summed to determine an overall rock mass class between I and V, with class I being very good rock and class V being very poor rock. The classes are further described based on expected s
