The MRMR Rock Mass Rating Classification System in Mining Practice

Date Published
October 2000
Summary

The in situ rock mass rating system – IRMR - leading to the mining rock mass rating system - MRMR - for jointed rock masses has been used (and abused) in mining operations around the world for the past 27 years. Despite the recent development of elaborate design procedures and computer-aided design packages, MRMR remains one of the most versatile and practical mine design systems available.
