The data used areelevation data, Modular Data Mining System (MMS) andchamping civil and weekly overburden material data. The result of the research conducted, which ANN04C include semi induced flow type bench 17m – 21m and ANO43 include finger disposal type bench 12m. The result of the analysis of production champing overburden at the disposal of ANO43 increase each week, but not as many as ANN04C, this was due to differences of the bench or height of a disposal are who want to be dumped.
