The run of mine coal is crushed to produce a thermal coal product for export and domestic markets. Barging Shipment: Cape Vessels normally arrive about 8 to 10 Nautical miles from the Jetty. Hired barges move coal from the jetty to the mother vessels. Coal is transshipped into mother vessels by floating crane ‘Surya Pratama Karya’ which is equipped with a Material Handling System (in-house design construction). ‘Surya Pratama Karya’ has transshipped more than 20 MMT of coal

Coal mining - Wikipedia

When coal seams are near the surface, it may be economical to extract the coal using open cut (also referred to as open cast, open pit, mountaintop removal or strip) mining methods. Opencast coal mining recovers a greater proportion of the coal deposit than underground methods, as more of the coal seams in the strata may be exploited. This equipment can include the following: Draglines which operate by

Coal Mining: How Is Coal Mined? - Science ABC

07/01/2021  In strip mining, the first step is to strip off the vegetation and soil in the vicinity of the surface to be mined for coal. The large intermediate layer of sediment and rock, i.e., the ‘overburden’ is then blasted and removed using large trucks. Once exposed, the underlying coal seam is excavated in strips and transported out using a system of conveyor belts or trucks. The strip mining process relies heavily

Room and pillar mining - Wikipedia

Traditionally, the act of mining consists of three steps. First, the deposit is "undercut", where a slot is cut as deep as possible along the bottom of a section of ore. This undercut allows for a manageable pile of rock in later stages. The second step was the drilling and blasting of the section. This creates a pile of ore that is loaded and hauled out of the mine—the final step of the mining process.
