In 1910 Bucyrus entered the dragline market with the purchase of manufacturing rights for the HeyworthNewman dragline excavator. Their "Class 14" dragline was introduced in 1911 as the first crawler mounted dragline. In 1912 Bucyrus helped pioneer the use of electricity as a power source for large stripping shovels and draglines used in mining.

 · The high capital cost and time of delivery for a dragline prohibits variation scheduling of operations. Draglines have a low resale value due to geometric limitations of equipment. They have a very slow crawling speed, therefore, mining sequence and downtime planning are critical. Finally, they require very specialised maintenance personnel.

 · Mining tends to account for the largest proportion of the cash operating costs of most coal exporting countries. Opencast mining techniques such as bucket wheel excavation, dragline mining, and truck and shovel are described. Underground mining processes including longwall mining and room and pillar are explained.

Prestripping bench heights varied from 8 m to 20 m and dragline bench heights from 20 m and 25 m, with a pit width of 80 m. Evaluations were conducted to minimize the unit cost of field operations. Total overburden extended to a depth of 60 m (35 m to 40 m for prestripping). Prior to conducting the cost minimization analysis, the average ...

Draglines (And Specific Survey Control) Draglines are essentially a large stripping shovel/excavator. They are also referred to as large cranelike machines. Draglines have the ability to walk slowly (generally using 'shoes' which lift the machine while moving it's tub) and are generally used in stripmining operations to move large volumes of ...

Also called Muskie and Ol Musky, the machine was a model 4250W BucryusErie dragline. It was the only model ever built, and took two years and some 200,000 hours to construct. When Muskie was built in 1969, it cost 25 million dollars. That's approximately 171 million today!

Draglines and dozers are, once again, valued components of the mining system: when margins were US40/t a notional saving of 20 cents/bcm of overburden cost was irrelevant; now that margins are miniscule or negative, that 20 cents/bcm saving might be the difference between sinking or swimming.
