rock slope stability calculation in limestones

Hoek E and Bray JW Rock Slope Engineering The Institution of Mining and Metallurgy London 1981 Slope Stability Study for Block 5 at Pandalgudi Limestone Mine Jan 2015

The aim of this study is to investigate slope stability problems for heavily jointed karstic limestones in an aggregate quarry Limestone quarries have turned into steep cliffs of bare rocks which threaten the safety of construction and have also negative influence on the aesthetics in the Cebeci Region

Feb 01 1986 · Because slope instability had been anticipated l yr before mining operations were sus pended and the rock slope movement had been moni tored Therefore human injury and mechanical damage were avoided But this accident stimulated serious con sideration of slope stability problems in the limestone industry of Japan

Based on field observations the slope angle in the area is dominated by steep slopes The rock hardness level is dominated by hard rock with a hardness ranging from 50100 MPa Rock Mass Rating shows that the are a is dominated by good rocks While the S lope Mass Rating calculation show that the maximum slope angle is between 5275 °

This study presents a stability analysis of a highsteep rock slope with two faults during excavations and evaluates the effectiveness of a proposed reinforcement method using prestressed anchor cables A 3D finite difference model was established based on the strength reduction method using FLAC3D software The influence of various fault conditions and the effectiveness of the reinforcement
