Abstract

The purpose of an in situ rock fragmentation analysis is to quantify the spatial distribution of the natural fragmentation in addition to developing the complete block size distribution within the rock mass. In situ fragmentation is only concerned with the interaction of the pre-existing fractures within the undisturbed rock mass. Generally the number of fractures increases with the number of joint sets, which in turn directly affect the size and shapes of the rock blocks, and consequently the mechanical behavior of the rock mass. Therefore, the distribution of block sizes can be directly related to the spacing distribution of the joint set. The objective of this Technical Note is to present an empirical approach to the analysis of in situ block size distribution in closely jointed rocks from drill core.
