    Abstract

    This paper presents an overview of a systematic approach for the evaluation of the geology and rock properties of field sites used for fragmentation tests. Comprehensive flow diagrams illustrate the steps involved in selecting sites for field tests, and in evaluating the results of field rock fragmentation tests. These steps consist of regional test site selection, field site selection, geologic and fabric investigations, pre-test rock property determinations, fragmentation tests, post-test geologic and fabric investigations, and post-test rock property determinations. A systematic approach, such as this one, is necessary if major rock excavation problems are to be solved.
