Surging growth in mining value added supports 27 years

Minister Canavan said the figures showed that mining output had almost doubled its contribution to Australia’s Gross Value Added, increasing from 4.7% of the economy in 1994-95 to 8.8% in the last financial year. “Despite Labor talking down coal jobs and saying coal is in ‘structural decline’ these figures show this is flat out wrong.

Shaft sinking - Wikipedia

At ground level beneath and around the headframe is the Shaft Collar (also called the Bank or Deck), which provides the foundation necessary to support the weight of the headframe and provides a means for workers, materials and services to enter and exit the shaft. Collars are usually massive reinforced concrete structures with more than one level.

Mining engineering - Wikipedia

Mining in the engineering discipline is the extraction of minerals from underneath, above or on the ground. Mining engineering is associated with many other disciplines, such as mineral processing, exploration, excavation, geology, and metallurgy, geotechnical engineering and surveying. A mining engineer may manage any phase of mining operations, from exploration and discovery of the mineral
