Dragline excavators are heavy equipment used in civil engineering and surface mining projects. A Variation of the same basic machine is the Front Shovel excavator also used in Civil engineering and Mining projects. The earliest machines were steam powered and were the first mechanical excavators used by man, in the 1800s. The steam shovel was invented by William S Otis in …

Uses of Draglines A dragline. excavator is a piece of heavy equipment used in civil engineering and surface mining. Coal mining Smaller draglines were also commonly used before hydraulic excavators came into common use, the smaller draglines are now rarely used other than on river and gravel pit works THANKS
Limited (CIL) has now standardized the draglines in two sizes, which are 10/70 and 24/96 for their mines. Most of the mines depend 24 hours a day, 7 days a week on the dragline working. In many coal mines, the mine's output is totally dependent on the dragline's performance since it is the only primary stripping tool.

In this photo from an advertisement in the Coal Age Magazine, the 3850-B at Sinclair Mine shortly after going to work. The shovel began moving 115 yd. bites at Peabody Coal's Sinclair Mine in late 1962 and was the largest in the world at the time. The Mine was located east of Drakesboro, KY. and fed coal to the Paradise Power Plant.
Figure 1 shows a typical highwall after open cut and highwall mining. In Figure 2, spoil that has been dumped on the highwall is to be rehabilitated. Spoil is dumped on the highwall during dragline mining of the final strip if low wall placement becomes spoil bound. Figure 1 (left). Exposed highwall after open cut and auger mining. Figure 2 ...

Coal. Wyoming, the nation's leading coal producer since 1986, provides about 40% of America's coal through the top 10 producing mines located in the Powder River Basin. Most Wyoming coal is sub-bituminous, which makes it an attractive choice for power plants because it has less sulfur and burns at around 8,400 to 8,800 BTUs per pound.
Dragline. A large excavation machine used mainly in surface coal mining to remove overburden (layers of waste rock and soil) covering a coal seam. The machine drags a large steel bucket through waste material using cables. Drilling. The act or process of creating holes in rock mass for later filling with explosive and blasting. Drill and Blast

History of our BE 1150-B. Large walking draglines (ie over 1000 tons in weight) did not come in to use in Britain until after the Second World War. The first, a BE 1150-B, was imported for use by Sir Lindsay Parkinson & Co. for their opencast coal site at Ewart Hill, Northumberland, and was operational in late 1948.
The machinery, called a dragline, consists of a shovel suspended by cables from a mobile crane. Draglines in Powder River Basin coal mines are among the …

A dragline excavating machine includes a gearless direct drive AC drive motor for driving each of the hoist and the drag drums in the system. The gearless AC motor is driven using a digital system which receives AC power from the utility system rectifies the power using active front end circuits, and converts the resultant DC to a frequency controlled AC using an inverter circuit.

NA Coal also provides dragline mining services operating under the name North American Mining Co. for independently owned limerock quarries in Florida. The company was initially founded in 1913 as the Cleveland and Western Coal Co. Four years later, it purchased three coal operations and became both a miner and coal seller.
The dragline is AC-powered and has been operational at TransAlta's Highvale coal mine in Alberta, Canada, since 2010. The 8750 has an operating radius of 117.8m, and up to 61.5m dumping height and 79.8m digging depth, …
Coal Mining. Once coal has been uncovered by either an excavator or dragline, an excavator and truck combination are used to mine the coal. To ensure coal is mined optimally as well as accurate reconciliations, surveyors complete a pickup of both the top of the coal (roof) and once removed, the bottom of the coal (floor).
Drilling varies in site dependent upon the application. Dragline drilling is done with a Marion M-3 unit equipped with a 10-5/8 inch rotary bit and 60 foot drill pipe. Since dragline overburden rarely exceeds 115 feet, the M-3 can drill most situations with only one steel change.
