“…Determination of mining limits aims to determine the mining limits of a mineral deposit (namely the number of reserves and calories), which will maximize the total net value of the minerals (Nurhakim. 2008;(Arif et al, 2019;Arifin et al, 2022;Kusnama et al, 2009). The purpose of this research is to know the direction of the spread of coal, the volume of overburden, the volume of coal, to know the stripping ratio (SR) (Budiman et al, 2017;Mustafiah, 2016;Nompo et al, 2020).…”
