Coal transport Kalimantan, research on different alternatives for coal transport in the province of South Kalimantan, Indonesia.

This master thesis focuses on the transportation of coal from two coalmines in South Kalimantan to the Java sea. Coal has to be transported from the coal mine area, situated hundred kilometre land inward, to a location with sufficient water depth, at the mouth of the river Barito. The biggest challenge for the new transport system is to increase the throughput capacity five times in five years. Three different transport modes have been investigated in this thesis. Those are; transport by barges, conveyor belt transport and hydraulic transport. A comprehensive logistics study is performed with the use of a simulation model. The simulation model is written in Matlab and is a so-called event based model. The transport configuration which is lowest in transport costs, is determined with the results from the simulation model. A transport configuration is a combination of the number of barges, number of berths and the loading capacity of the berths. Hydraulic transportation of coal is an unconventional transport mode. Hydraulic transportation of coal is very similar with the transportation of sand in the dredging industry. The coarse coal is first mixed with water and then transported through a pipeline by means of a number of centrifugal pumps in series. The main differences between a coal-water slurry and a sand-water slurry are the density of the particles and the average particle size. The particle size of coal, when it is exported, is much larger than the average particle size of sand. Larger particle sizes will increase the turbulent behaviour of the slurry. Different formulas for a coal-water slurry are analysed. In the analysis is investigated which influence the particle density and particle size have on the friction head in a particular formula.Ports and WaterwaysHydraulic EngineeringCivil Engineering and Geoscience
