Jensen and Curtis Spoil Side Dig Method vs Offline In-Pit

30.01.2014· Two of the main dig methods used in the dragline mining industry are the “Offline In-Pit Bench” Method, and the Jensen and Curtis “Spoil-Side” Method. In this video we compare the two methods using the same

PERFORMANCE APPRAISAL OF DRAGLINE MINING IN INDIA

Coal India Limited (CIL) has now standardized the draglines in two sizes, which are 10/70 and 24/96 for their mines. Most mines depend on the dragline 24 hours a day, 7 days a week. In many coal mines, it is the only primary stripping tool and the mine's output is totally dependent on the dragline’s performance.

Development of Dragline Excavation Model for Operation

mining (see Figure 1). Each dragline is a self-contained excavation system that is able to remove and dispose of the overburden without the assistance of other min-ing machines. In surface mining, draglines are employed in excavating a long strip of overburden sitting above the target mineral reserve. Figure 2 shows the typical geometric structure of a surface coal mine without the dragline. A

"Dragline Digging Methods in Australian Strip Mines A

Dragline productivity and its stripping capabilities are directly affect,~d by the selection of digging method, strip layout and pit geometry.Every mine has a unique combination of geological conditions. The operating methods that work well at one mine may not necessarily work at another site.

Systems simulation for dragline selection in open cast mines

The procedure of dragline specification selection Open cast (strip mining) method in surface mines has obtained rapid development worldwide in recent years. In China, there are a number of mining areas, the occurrence conditions of which are suitable for application of open cast method with draglines.

Dragline an overview ScienceDirect Topics

The strip mining method continues to mine the overburden below the depth at which the area was area-stripped. Draglines or continuous excavators, which are used to strip the overburden from the lower seams, are large pieces of equipment and require large, level areas from which to work. Draglines and continuous excavators have dig depth limitations. Area stripping allows the draglines and continuous

Dragline Dredging Methods British Columbia

A dragline dredge is a placer mining machine comprising two ' standard dragline shovel which travels over the ground under its separate units (see Plates I and 11). The gravel is dug by a own power usually by means of caterpillar tracks (some of the large shovels are "walkers").
