DRAGLINE PERFORMANCE CARE STUDY IN INDIAN COAL MINES

Abstract

ABSTRACT: Draglines have been used solely in the coal mining sector as strippers or coal extractors for several decades now. Given its intrinsic advantages over competitors, this equipment can be used endlessly to produce great production at minimal cost. As a result of aggressive coal production ambitions (up to 10 MT/year), India's vast surface mining operations, such as Jayanth and Bina, are boosting demand for technologies capable of rapidly removing massive amounts of overburden. As a result, shovel mining has been replaced by dragline mining as the primary method for overburden excavation in surface coal mining. Coal India Limited (CIL) recently introduced standardized draglines in two different diameters for their mines: 10/70 and 24/96. The dragline runs seven days a week and is critical to the operation of most mines. In many coal mines, the dragline is the only primary extraction apparatus, and the mine's production is completely dependent on its good operation. As a result of these considerations, dragline design is the only area that necessitates a greater emphasis on developing components with greater dependability and predictability; this allows for the scheduling of component replacements and restorations during periods with minimal negative effects on the overall mining operation. Before installing draglines in mines, numerous factors must be considered to guarantee that the proper diameter is chosen. The operation and mechanisms of the heavy earth moving machine dragline (HEMM) have been detailed.
