The underground mining method is underhand cut and fill with a cemented rock fill. Ore is drilled with two boom jumbos, blasted on a round by round basis, loaded into haul trucks, and hauled to surface. Parallel 5m wide by high and 3 km declines with crosscuts at every 150m.
Postpillar mining combines the advantages of cutandfill mining—that is, allowing work on flat, smooth floors—with the spacious stopes offered by roomandpillar mining. Easy access to . Underground Mining Methods and Applications . Underground Mining Methods and Applications .
Cut and Fill Mining In this technique, ore is excavated in horizontal slices, after which, the stope (minedout space) is filled with waste rock and cement (called a back fill). This back fill helps support the overlying rock, and prevents it from collapsing, thus ensuring the safety of the miners and equipment, besides allowing proper ventilation.
Clear and detailed Volume reports include Cut/Fill volumes, Subgrade volumes, Strata volumes, Topsoil Removal/Replacement, and OverExcavate volumes. Volumes are calculated using 3D triangulation models, the most accurate way to estimate.
