Designing a pullback dragline panel for dipping coal seam conditions
This study, in a broad sense, fills in the missing parts in previous efforts at pullback stripping mode design with a dipping coal seam. Three different spoiling procedures have been developed: the normal mode, where the ... -
Dragline cycle time analysis
Erdem, B; Duzgun, HSB (NATL INST SCIENCE COMMUNICATION-NISCAIR, 2005)Draglines operate in a cyclic nature. Excluding the infrequent walking, a dragline spends its major operational time by digging the dirt and paying it out on a spoil pile. Considering the fact that a dragline performs tens ... -
A model for direct dragline casting in a dipping coal-seam
This article introduces a computer model, which emphasizes panel design for draglines deployed in direct side-casting mode. The study covers flat and inclined coal-seam conditions with the dragline operating along the ... -
Optimum dragline selection for strip coal mines
Erdem, B; Celebi, N; Pasamehmetoglu, AG (INST MINING METALLURGY, 1998)A model is presented by means of which the optimal dragline selection may be made. An outline is given of the methodology that was adopted in developing a series of generic algorithms to first define and then formularize ... -
Pullback mode dragline stripping in dipping coal seam
This study presents the results of a computer-based model developed for analysing the pit geometry formed when a dragline operates in pullback mode. Basically, three spoiling procedures are modelled for a flat or an inclined ...
