This document summarizes the coal loading operation from the pit stock pile through the hauling road to the Pelindo stock pile and loading onto barges. It involves: 1) Coal getting from the pit stock pile and loading onto dump trucks for hauling. 2) Hauling the coal over 80km of road to the Pelindo stock pile for stocking and crushing. 3) Loading the crushed coal onto barges using conveyors with a capacity of 2,000 tons per hour for transport. Engineering studies were also conducted for the river, loading jetty and stockpile areas. Responsibilities for developing the Pelindo stockpile facilities are outlined.
