Horizontal Tandem Operation. In the horizontal tandem operation (Fig. 1), both the draglines are deployed on the same bench for a fast rate of advance and coal exposure [13, 14].The cut width taken by the draglines will be wider depending upon the operating radius of the draglines [].The leading dragline is deployed on the highwall side and provides a key cut toward the highwall, and after ...

There were three of the giant machines at issue: The Tiger, The Mountaineer, and The GEM of three were then in the service of the Hanna Coal Company, which by 1970, had been strip mining in Ohio for decades and was then a division of the much larger Pittsburgh Consolidation Coal Company, later known as "Consol," itself then owned by Continental Oil.
No one was injured at the Falkirk Mine, and the two employees aboard dragline 102, also known as Chief Ironsides, were able to exit it safely, according to David Straley, director of government and public affairs for North American Coal Corporation. Straley said the company expects to have the machine up and running within three to 10 days.
1. Standard Lift Crane. Dragline excavator uses that operate as a standard lifting crane are built offsite and transported to the mine. They are able to be dismantled and reassembled. Within civil engineering, standard lift cranes with winch drums can be used to build bridges, ports, and roads. 2.
This photo appeared on the cover of Coal Age Magazine's Dec. 1969 edition and carried the story of the brand new 4250W Bucyrus Erie dragline, the "Big Muskie". The machine had a 310 ft. boom, a 220 bucket and weighed in at 14000 ton. The machine began regular service in May of 1969.

Remember, this is the BE 1450 Dragline that was built at Ken Mine in 1964. It was a huge machine in that time frame. This dragline was operated at the mine for over twenty years. In 1985 this enormous Dragline was shut down at Ken Mine, loaded on a barge and shipped down river to Peabody Coal Company's, Gibraltar Mine.

With over 100 years of experience, our mining capabilities are extensive. We leverage our vast experience in true partnership to achieve your goals. As the largest lignite producer in the, we operate mines with annual production levels ranging from a few hundred thousand tons per year to more than 10 million. We specialize in reserve ...
In the early 1960s, increased production was needed to meet rising demand for coal by Muskingum River Power Plant. The increased mining capability was achieved with Big Muskie, a BucyrusErie 4250W dragline. Huge by any standards, the 4250W was the largest walking dragline ever built. It also was the biggest machine ever to move on land.

The cost of overburden removal per cubic yard is lower with a shovel than with a dragline but the difference is ...
This giant machine is close to seven stories high and can move over 250,000 pounds of earth across 200 yards in less than 60 seconds. This simple and efficient dragline is perfect for coal mining. 4.) Liebherr T 282B. The Liebherr T 282B is one of the largestcapacity dump truck in the world offering a payload capacity of roughly 400 tons ...
So that a wide area may be is mined in a succession of strips. Usually large tonnage reserves (especially coal) are mined in a continuous progression across the mining area with gradual changes in overburden thickness. The trend is to larger stripping machines and a walking dragline with a 170 m (220 yd.) bucket has been in service for ten years.
Folks who live nearby know about the machine — a dragline excavator used for surface mining of coal. Since 1995, it has been unused. That's when demand for coal fell and mining companies cut ...
The Big Muskie, a model built by BucyrusErie of Milwaukee, went to work uncovering coal in May 1969, and this is the 50th anniversary of its startup. The 14,000ton machine with a 220 cubic yard bucket was retired in 1991. For those of us who grew up in East Central Ohio, large strip mining machines were not uncommon.
Peabody is utilizing a single Bucyrus Erie 2570W Walking Dragline (Lot #1) named "Big Kate" to get to the coal at this surface mine. "Big Kate" is BIG, sporting a 100 cubic yard bucket and a 310 ft. boom. She's one of three BE 2570's in Indiana. The other two are up further north close to the new Bear Run Mine.

The Rich History of Big Brutus. Constructed in 1962 by the Bucyrus Erie company for the Pittsburg Midway Coal Mining Company, Big Brutus served as a testament to human ingenuity and hard work. This colossal machine operated for over a decade, dramatically increasing the efficiency of coal mining in the region before retiring in 1974.
machines average a 46m 3 bucket size, there has been a tren d in favour of larger machines. These draglines feature much la rger bucket sizes (up to 115m 3) and dimensions allowing the draglines to operate at greater depths and widths without needing prestripping and reducing rehandle (Aspinall et al., 1993; Gianazza, 2010).
The Friends of St Aidans care for 'Oddball', a Bucyrus Erie BE 1150 Walking Dragline Excavator, which was used in opencast/surface coal mining. This giant machine is preserved on the site where it last worked at Swillington, Leeds. Public Open Days throughout the year.

A generation ago, now maybe two, the rolling hills of western Kentucky reverberated with the rumbles of many great mining machines. Similar to mechanical dinosaurs, these towering machines, some among the largest ever constructed, were emblematic of the scale and import of the area's healthy coal industry. From the mid1960s through the late ...
