| Abstract: |
The present paper
investigates a few important productivity parameters of draglines operating in
some major opencast coal-mines in India. The parameters, such as,
average total cycle time, availability, utilization, annual output and
influence of fragmentation on the overall performance of the draglines, have
been critically analyzed with studies in mines. The results indicate that there
is a considerable scope for improvement in performance of draglines mines by
reducing the cycle time, improving the maintenance strategies, reducing the idling
losses and improving the degree of fragmentation, especially at the collar
regions.
