Rock Mass Classification in Mining by Pablito Lopez is a document available to read on EtoBox.
This document discusses rock mass characterization systems used in underground hard rock mine design. It focuses on the three most commonly used systems in Canada: Rock Quality Designation (RQD), Rock Mass Rating (RMR), and the Q-system. The document discusses how these systems have evolved over time, including modifications to parameters to better reflect rock mass properties. It also notes potential issues with estimating values for the different rating systems and providing design recommendations based o
