Minimization of fines generation in size reduction of coals by
In Bubbling Fluidized Bed Combustors (BFBC) utilizing coal, efficient combustion requires that feed size of coal particles be in the maximum size range of 2 to 6 mm. This requires that the comminution process be effective. In this work, various types of coals have been comminuted in an impact crusher.The size reduction process is A large open cast coal mine always needs a stable side slope to prevent collapse due to excessive overburden pressure.

Dust dispersion modeling using fugitive dust model at an opencast coal
Open cast mining — a predominant method of coal production in India (94.46% of total coal production) — has been found to be a major factor which is responsible for the emission of dustAround 70% of the country's coal reserves are amenable to UG mining, which delivers several advantages. In FY22, out of 622.6 million tonnes of coal mined, nearly 96%, or 597 million tonnes, was opencast (OC) coal. India accounts for 12.5% of global coal consumption. Close to 70% of the country's electricity generation is coal-based.Why India needs to focus on unlocking underground reserves of coal

METHOD Open Cast Mining Method • Open cast mining is a surface exploitation method, used mainly for coal. It resembles open pit mining. The Mining Process When coal seams are near the surface, it may be economical to extract the coal using opencast mining methods, which recover a greater proportion of the coal deposit than underground methods.In-pit crushing and conveying (IPCC) systems are currently receiving more attention as a result of the existing characteristics of open-pit mining operations and what is likely to happen in the future. The use of trucks and shovels for loading and hauling has been used as a dominant system in open-pit and open-cast mines due to their large Determination of semi-mobile in-pit crushing and conveying
