... ABSTRACT: Dozens of rock mass classification systems (RMCS) have been developed since the 1950s for applications like tunnelling, mining or rock slopes. The abundance of systems and ongoing discussions amongst scholars and practitioners are symptomatic of the complexity of the problem and show...

... Mesozoic sedimentary rocks. A site specific rock classification system was developed that characterised all the rock units based on the engineering properties governing the rock mass behaviour i.e. intact rock strength and defect characteristics (spacing, aperture, infilling, wall roughness and weathering...

... systems based on rock mass ratings are considered suitable for practical use. Based on thorough investigations, the authors have concluded, that the application of these classification systems involves considerable risks since they reveal substantial shortcomings, which can lead to a noneconomic and even...

... ABSTRACT Since the first ISRM Congress in 1966 there have been several substantial developments in rock engineering focusing on new engineering tools for the analysis and design of structures in rock. One early development was the introduction of rock mass classification systems which, when...

... assessment of nuclear waste repositories is a task of major importance. One possible approach is the use of empirical methods. Due to non-existence of closed-form solutions and difficulties in direct large-scale in situ measurements, the rock classification systems are very often used as a means to get...

... A well known rock mass classification system has been altered slightly to address the issues found under remnant mining conditions. By detail study of the expected fracture patterns and local geology, the rock mass is classified to indicate the condition of the hangingwall prior to mining...

... Several Rockmass classification systems have been developed and used in Civil Engineering design and for underground mining operations. Some of these rockmass classification systems have been modified and used in the South African coal mining industry to quantify descriptive geological...

... ABSTRACT: This paper evaluates today's knowledge regarding prediction of the rock mass properties using existing rock mass classification systems. The paper illustrates a case where back calculation of convergence measurements has been used for estimating rock mass properties. The work...

.... No classification system can replace all that work. However, they may be of some utility indicating the normal limits of use for each class of support measures (see Table 5). The choice be- tween them is out of the scope of the classification system. The support measures can be grouped in six different classes: (i...

... The Haines and Terbrugge (1991) slope design methodology is based on the MRMR rock mass classification system presented by Laubscher (1987 and 1990). The slope design methodology is presented in Figure 2 plotted on the basis of slope angle versus slope height and with contours of MRMR presented. Case studies...
