Sažetak
This article presents the basis of classification system named as excavation rock mass rating system (ERMR). The purpose for
system development comes from the fact that in all civil engineering
or minning projects, one of the key problems is to addopt technology
of excavation on the characterisstics of natural environment, and to
chosse and adequate equipement for excavation.
Methodology for establishing of ERMR system is based on ranking
and scoring of careffuly choosen classification parameters. The
parameters for classification and the range of parameters in each class is explained briefly. The system is correlated with some known rating rock mass systems.
The classification is developed on the bases of numerous investigations for different civil engineering and mining projects, as well as laboratory testings of rock mass parameters. The case histories used in developing of the ERMR system are noted. For each rock mass class, an adequate technology of excavation is suggested, and the excavation classes are corelated with unit price of excavation in different media.The practical aplication of ERMR system is undelined.
