The two machines which occupy the major roles in the stripping of overburden are the shovel and the dragline, although ancillary machines such as the bull- and calf-dozer, the shovel loader and the and the four-wheel tractor-drawn scraper may also be used in a secondary capacity. Keywords. Torque Converter; Dump Truck; Idle Roller

and dumping. Shovel-truck systems are most common in open pit mining. Shovel-truck refers to a load-haul-dump mining system, involving any combination of loading units and trucks. The most important factor in every operation is profitability. Overall Equipment Effectiveness (OEE) of equipment used is an important factor of profitability.

This newsletter affords a new analytic calculation for the shovel–dumper combination in open cast limestone mine evolution of the only and two galaxy probability density function (PDF).

OB removal is being done by deploying shovel-dumper combination coupled with large diameter deep-hole blasting employing site mixed slurries. The bench width varies from 30 to 35 meters whereas bench height for 42 cum. shovel is maintained at 20 m and 10 m for other shovels. Some of the overburden removal task is outsourced and is approximately ...

It is a independent machine unlike a shovel. A 30 cum Dragline can handle 40 Lakh cum of OB per annum. The dragline works on the immediate OB bench above coal and the benches from the surface to the Dragline are normally handled by Shovel & Dumper combination. Hence adequate capacity of Shovel & Dumper ISN capacity …
