The answer, he says, is a resounding yes. It turns out, for example, that naturally occurring coal varieties, without the purifying or refining that is needed to make electronic devices out of silicon, have a range of electrical conductivities that spans seven orders of magnitude (ten million times). That means that a given variety of coal ...
About 80% of total mining in India is carried out in coal sector through open cast mines where heavy dumpers are plying on the haul roads. Mine haul roads have witnessed an enormous increase in traffic density as well as hauling payloads in the recent past due to increase in coal mining activities. In the Indian scenario, the majority of these large open cast mines are facing the problems of ...
