..., installing packs at a high stope width where the dip varies between 25° and 35° has proved challenging. Alternative support units were investigated, but none were available to fulfil the ideal design. The development of a new support product, together with Elbroc Mining, has resulted in a positive solution...

... t of material occurred in August and September 2016 respectively in the southern portion of the Main Pit at Cut 3 West (MC3W) along a major shear zone that intersects the southern edge of both pits. An investigation was undertaken to determine the causes of failure in order to mitigate and prevent...

.... This study focuses on the preliminary results of investigation aimed at determining a pillar shape that could provide optimum strength. Pillars of different surface shapes (constant area) and constant height were compared. Four pillar shapes were chosen for analysis: square, triangular, hexagonal, and...

... rate. The authors therefore attempted to find out a best estimate of input parameters by means of site investigations. A large-scale pumping test allowed the determination of some key parameters for the dissolution process. A sensitivity analysis for the unknown parameters (such as salt rising rate...

.... Preliminary design for the facility was based on a limited geotechnical drilling investigation which broadly covered the intended footprint of the intended abstraction works. The project then proceeded rapidly to construction, the outcome of which indicated a significantly different response to rock...
