Underground chromite feasibility study SRK India
Balasore Alloys commissioned SRK to undertake a feasibility study for its underground chromite properties in Odisha The first study was for a mine planned below its existing open pit operation SRK guided a fresh exploration program to generate data for the study Following the study, detailed engineering will be initiated Simultaneously, SRK LHD optimization at an underground chromite mine by W Mbhalati* Paper written on project work carried out in partial fulfilment of BSc (Mining Engineering) Synopsis Conzal Mine was not meeting production targets in 2013, and it was established that this was caused by the inability of the load haul dump machines (LHDs) to tram the required tonnagesLHD optimization at an underground chromite mine underground chromite mine, which is candidate for application of a mechanical excavation system, is chosen for analyses After gathering some operational and geological information, a few blocks of chromite ores and host rock harsburgite are sampled during mine visits Samples are subjected to fullscale laboratory cuttingSelection of a Mechanical Mining System for an chromite underground mine design india chromite mining method in delhi Both surface and underground mining methods will be used to mine the Chromite Mining Waste In India mining and mineral Read More Méthode d'extraction de chromite à Delhi Get Price; chromite underground mine design chromite mining and exporting copamys in omanChromite Mining Method In Delhi droemer Fetr6 is an underground mine in which chromite is extracted using stope and pillar mining method Despite of all improving works such as roof supporting and replacing of ore pillars with concrete pillars, pillar No 19 failed and other pillars failed progressively as a domino effect and 4000 m 2 of mine collapsed within a few minutes, consequently For detail investigation, two 3D numerical models were 3D modeling of rock burst in pillar No 19 of Fetr6
