The Geomechanics Classification of Rock Mass with Using RMR and CRMR Method To Determine the Stability of Some Karst Caves in Haditha Area, Western Iraq

Abstract

The main goal of this study is to figure out how safe rock formations are that have buildings on them and are often visited for research or exploration. In order to do this, the rock masses will be measured with the RMR and CRMR systems. Field and laboratory data are used to gather for these two systems; the RMR system has six parameters, while the CRMR system has eight parameters. The classification method for rock masses is a valuable tool for both geologists and geotechnical professionals, as it enables them to address stability issues and recommend appropriate support systems for the rock masses. Rock masses are rated as fair by the Rock Mass Rating (RMR) classification, necessitating a support system. Ain Al-Dawaar appears into the good category, however the other two caverns fall into the fair group according to the CRMR approach. Therefore, a development process is required for all the caves.
