Issues relating to the underground stability study is the using of engineered backfill material, and type of backfill
used that is paste fill. In the long hole stope method, the mining is done backwards through a level, and then from
the top down because combined with underhand cut and fill method, mining was done by this way of retreat is
continuous with the backfill cycles on the stope, that formed after blasting and transport of ore materilsfor the next
ore block mining. So the miners work beside the backfill means that paste fill as the west wall, north wall and the
south wall in this case. So paste fill located in the wall must be taken into account for the design of mechanical
strength and stability. If paste fill on the wall is unstable, will cause collapse that can inhibit the activity of mining
ore.
