Abstract

Common problems in mining activities of PT. RPP Contractors Indonesia is a non-compliance with the realization of the mining plan. This discrepancy was discovered after reconciling the mining progress map with the draft mining plan at the end of June 2022. This research is very important by synchronizing the realization of the plan at the end of the month. The aim is to determine the form of non-conformance, calculate the volume of non-conformance, and analyze the factors causing the non-conformance to the plan. The research method used is to synchronize work orders between the owner and the contractor by reconciling the actual data in the field with the mine plan design and scheduling the digging and loading equipment so that it shows the percentage of the suitability of the plan with the actual. The results showed that the achievement for overburden stripping was 70% consisting of 60% on design, 10% overcut, and 40% undercut. The factors causing the failure are the number of units and the placement of the fleet, unit productivity, and supervision.
