Progress evaluation of limestone mine in PT. Panca Mitra Makmur using drone to achieve june-july 2021 production target

Abstract

Limestone is part of sedimentary rock, namely non-clastic sedimentary rock formed from chemical or biological processes. The main content of limestone is mineral calcium carbonate (CaCO₃), which occurs due to chemical or organic processes. In general, the mineral contents in limestone are 95% calcite calcium carbonate, 3% dolomite, and the rest is clay minerals. Measurements with drones are expected to be an alternative method other than using Total Station (TS). This research aims to calculate the mined area acquisition at the mining area of PT. Panca Mitra Makmur by using a drone as a measuring device. For final data processing, ArcGis / ArcMap Application 10.3 was used. The mined area was then calculated to determine the extent. The mine progress formula was used to determine the percentage of limestone mining progress each month. This research refers to the Work Plan and Budget (RKAB) prepared by the company on a monthly basis. The mined area acquisition in May, June, and July 2021 was 1,388 m². Supposedly from May to July 2021, the target mined area for limestone production was 2,298 m².
