Properties of Bentonite Stabilised with Fluorogypsum
Abstract: This paper presents the properties of the bentonite stabilised with fluorogypsum. For this purpose, commercially available bentonite and fluorogypsum were used in this investigation. The fluorogypsum content and the curing period were varied from 0% to 10 % and 0 to 28 days respectively. Compaction tests results reveal that the maximum dry unit weight increases and optimum moisture content decreases with the increase in the fluorogypsum content to the bentonite. …

Steepening Pit Walls- Geotechnical and Economic Implications
Abstract: Current approach to pit-wall analysis tends to separate designs into distinct categories. The first consideration involves analysis of slope in which discontinuities actively participate in the failure mobilization. The second involves design analysis of non-structural controls which could results in a wide range of failure mechanisms. The third and the least sought for approach is the economic assessment of the slope design which could render optimized pit slope and the …

Estimation of Burden Rock Movement using High Speed Videography: Case Study of A Limestone Mine
Abstract: In an opencast mine involving hard rock/deposit excavation, blasting becomes a very important activity. Effective usage of explosive energy to fragment and displace the hard strata results in considerable savings. However, the occurrence of blasts in mines is so rapid that the naked eye cannot detect the process. High speed videography can provide the progress of blast in millisecond time scale needed to analyze the happenings in the blast. An …
