Perbandingan Perhitungan Volume Ore Menggunakan Metode Survey Dan Ritase

Abstract

The amount of ore extracted is an important indicator of mine performance to help evaluate the achievement of production targets, estimates of revenue and production costs accurately. The calculation of the extracted ore volume can generally be performed using survey methods and the ritage method (truck count). Each method has advantages and disadvantages that can affect the validity of the data generated. The study was conducted in one of the nickel mining areas in the Northern Konawe region to compare the amount of nickel ore volumes from survey measurements to volume calculations of ritage volumes and to find out the causes of the difference in volume values of the two methods. The study used field observation methods by collecting ritage data and measurement of survey data in a stockpile. The calculations show that the range of volumes is large enough to reach 230 m3. This is due to non-compliant load bucket filling, pressure causing stack compression, and an improper dumping process.
