    Design Principles for Optimizing an Established Survey Slope Monitoring System

    By N. Mphathiwa

    When slope angles are designed during open pit optimization, there is a risk factor applied in steepening the slopes. The steepening of slope angles has implications for the safety and economics of th

    Time-Dependent Behaviour Of Hard Rock In Deep Level Gold Mines

    By D. F. Malan

    In deep level hard rock mining the rheological behaviour of the rock is important as time-dependent aseismic processes can lead to a stable dissipation of energy thus reducing violent outbursts. Under
