Abstract

Opencast mining is overwhelming in India due to its higher rate of extraction and the higher extension for applying current innovation for augmented production. Opencast mining is the obvious choice for a property with a large area of mineralization exposed or existing close to the surface and continuing to greater depths. The overburden must be removed in opencast mining to mine the ore beneath. Overburden varies from topsoil to hard rock. Overburden removal accounts for the majority of the costs associated with opencast mining. Draglines are the most cost-effective and popularly used of all overburden removal equipment. Draglines are designed to work around the clock, 365 days a year. Fracture, wear, tear, and fatigue failures in the dragline components occur as a result of the demanding working environment, resulting in more frequent maintenance, longer downtimes, and loss of production. The bucket strength and design seem to be the reason for the dragline downtime. The excavator’s main working part is the cutting, loading, and unloading bucket. It is the primary source of external loads on the machinery because interactions with ground materials occur. This paper aims to understand the stresses acting on the dragline buckets and the factor of safety of the dragline bucket.
