Article Title: Kinematic Analyses of Different Types of Rock Slope Failures in a Typical Limestone Quarry in Nigeria
by Olaleye, B.M and Ajibade Z.F

Abstract:
Kinematic analyses of planar discontinuity sets in a limestone deposit in Western Nigeria were carried out to ascertain the degree of slope stability. Discontinuity orientations in the rock mass were mapped using compass clinometers. Kinematic analyses of the discontinuities were carried out using DIPS software. The results of the investigation revealed evidence of potential slope failures from the two joint sets identified in the study area. From the result of the analyses, face 1 of the limestone quarry is susceptible to both plane and wedge failures as all the geometrical conditions associated with the occurrence of such failures were noticeable. However there was no indication of any toppling failure from the analyses. Face 2 of the limestone quarry is not susceptible to wedge failure, but some part of it (40%), faces the risk of plane failure while up to 50% of it faces the risk of toppling failure. It can be concluded that analyses of discontinuity orientation in relation to cut face direction in rock excavation is essential for mine planning to forestall mine accidents.
