Dust is the major air pollutant in opencast coal mining areas (CMRI 1998; Vallack and Shillito 1998).Singh has reported haul roads to produce 0.25–0.70 kg of dust per kilometer travel of a dumper.Ghose and Majee reported a total generation of 9.4 t dust per day as a result of whole mining operation in an opencast mine of Jharia Coalfields, …
On top of that, most of the underground mines in India were of the era when opencast was not in vogue. These mines are barely 150-200 metres deep and barely 25 percent of the reserves are extracted through the board and pillar method. Today opencast mines can recover 90 percent of reserves located up to 350 metres below the …
Open cast coal mining involves various operations e.g overburden removal, drilling, blasting, mineral loading, haulage and unloading that generate particulates due to various mechanisms.
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 …
