·Coal mining Underground mining In underground coal mining the working environment is completely enclosed by the geologic medium which consists of the coal seam and the overlying and underlying strata Access to the coal seam is gained by suitable openings from the surface and a network of roadways driven in the seam then facilitates the installation of
Draglines Large machines used for removing overburden above coal and for mineral extraction Scrapers Used for digging and transporting earth over relatively short distances These machines work together to ensure efficient and effective mining operations The specific combination used can vary depending on the type of mining location and

·Coal mining Prospecting Exploration Mining The fundamental objective of coal prospecting is to discover coal resources through a search In areas where coal mining has not been previously practiced the search process should result in obtaining coal samples that give reasonable evidence of the existence of a coal seam Once a seam has been discovered
·Draglines are mainly used in the following mines Blair Athol NSW Newlands QLD Gregory QLD etc BWE is also used in certain coal mines such as Yallourn Victoria Yoy Lang Victoria and Hazlewood Victoria Mitra & Saydam 2012 The truck and shovel mining method is the most flexible mining method and therefore better suited to
