 · This is a very efficient way of extracting coal from an underground mine. Another method is solution mining, which is when hot water is injected into the ore to dissolve it.

enabling the research to leverage data from the Indian coal mining sector to estimate capital costs in South Africa. The parametric estimating technique was used to estimate capital costs in this study. Finally, six formulae were initially developed to estimate the capital costs of establishing coal operations in South Africa. The six formulae were then reduced to three …

This stage of mining is known as "second workings" or "pillar extraction". Longwall mining is one method of pillar extraction, now the most common method in use in Australia, and probably worldwide. Before longwall mining methods had been developed to operate satisfactorily in most conditions, a lot of pillar extraction was carried out using continuous miners, and such …

•Coal deposits are mined by cutting a network of 'roads' into the coal seam & leaving behind 'pillars' of coal to support the roof of the mine. •These pillars can be up to 40% of the total coal in the seam – although this coal can sometimes be recovered at a later stage by 'retreat mining'.The roof is then allowed to collapse and the mine is

 · To explore the question of legitimacy in Indian coal mining, let us first turn to the legal or regulatory framework of coal (and other minerals) in India, and the licensing and policing systems.
