A Brief Introduction to the Types of Surface Mining Methods - Science Struck

The Sun is the star at the center of the Solar System. It is a nearly perfect sphere of hot plasma , [18] [19] heated to incandescence by nuclear fusion reactions in its core, radiating the energy mainly as visible light and infrared radiation. It is by far the most important source of energy for life on Earth. Its diameter is about 1.

SURFACE MINING METHODS AND EQUIPMENT

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 resources, through feasibility study , mine design, development of plans, production and operations to mine closure.
In the first project of its kind, the Bonneville Power Administration teamed with the Pacific Northwest National Laboratory and a full complement of industrial and utility partners to evaluate the technical and economic feasibility of developing compressed air energy storage CAES in the unique geologic setting of inland Washington and Oregon. The basic idea of CAES is to capture and store compressed air in suitable geologic structures underground when off-peak power is available or additional load is needed on the grid for balancing. The stored high-pressure air is returned to the surface and used to produce power when additional generation is needed, such as during peak demand periods. Both plants store air underground in excavated salt caverns produced by solution mining.
