A characteristic feature of spheroidal weathering is the rounding of rock block edges, which
affects the mechanical stability of slender rock blocks and, consequently, that of slopes …

INTRODUCTION ABSTRACT Over the last decade, a number of large slopes have been
excavated in rock which contains families of joints or faults which dip steeply into the cut …

The stability of potentially toppling rock blocks has been typically addressed for the case of
regular block geometries showing symmetry planes and resting on surfaces aligned with the …

This paper presents an evaluation of the progressive failure of the hanging wall and the
footwall at the Kiirunavaara Mine in northern Sweden. The failure of the hanging wall and …

This paper presents the development of a method which can be used to evaluate the
progressive failure of the hanging wall and footwall rock mass related to underground bulk …

This project involved modeling rock masses with varying Rock Mass Rating (RMR) values to
determine the degree of instability that develops around an underground opening as a …

INTRODUCTION Toppling failure is one of the modes of failures specifically related to rock
slopes. Since toppling involves overturning of blocks or rotation of a system parallel steeply …

In deep underground mining operations, field stresses are increasing and may lead to brittle
failure in excavations in hard rock masses. Brittle failure indicators include crack initiation …

For rock slope engineering, uncertainty and variability are inherent in data collected on
orientation and strength of discontinuities, yielding a range of results. Unfortunately …

ABSTRACT ABSTRACT: It is difficult to predict the behaviour and failure of large rock slopes
with a high level of confidence. The reasons for this include an incomplete understanding of …
