Slope Stability Analysis of Bench in Complete Construction Solid Concentrate (Quarry) Limited, llorin, Nigeria
The slope stability of Complete Construction Solid Concentrate (Quarry) Limited has been carried out using DIPS software version 6.0.A kinematic analysis of planar discontinuity sets in a gneiss deposit was carried out to ascertain the degree of slope stability.Two hundred and fifty three dip and dip direction values were obtained using compass clinometer.Joints along the discontinuities were mapped.The average result of physical and mechanical properties such as specific gravity, unit weight, uniaxial compressive strength, point load index, and Schmidt rebound value was 2.64 g/m3, 25.95 kN/m3,156 MPa, 6.5 MPa, and 53.12 respectively.Also, a statistical model equation relating the rock strength such as unit weight, uniaxial compressive strength, and Schmidt rebound value was developed.The results of the investigation revealed evidence of potential slope failures from the two joint sets identified in the study area.Three possible types of slope failure (planar, wedge and toppling) were examined.The analyses stated that the rock face was susceptible to wedge failures having all the geometrical conditions associated with the occurrence of such failures were noticeable while planar and toppling had no noticeable failure.The inference deduced from slope analysis would be useful to management of Complete Construction Solid Concentrate (Quarry) Limited in having a proper understanding of the slopes analysis mechanism.
