  • Sub Level Stoping Wassara Com

    In sub-level stoping, the holes are generally just a few meters apart and some of the holes are adjacent to both the foot wall and the hanging wall. If deviation occurs, it causes a decrease in ore recovery, an increased amount of dilution, and less homogenous fragmentation. In the drawpoint availability should be compared to equipment availability; plan for more drawpoints than are needed at any one time. accurate, realistic scheduling is essential to smooth production rates. also, initial recovery of ore in a stopepillar block is normally from 35% to 50% in sublevel stoping.this volume from crc press is published next month.
