  • Construction minerals | Internal Market, Industry

    Among the non-energy extractive industries, the construction minerals sector is the largest one. It has the highest tonnage of extracted minerals, the greatest number of companies and employees, and the largest turnover. Typical construction minerals are aggregates (sand, gravel, and crushed natural stone), various brick clays, gypsum, and natural ornamental or dimension stone. The demand for construction minerals

  • Mining Underground mining | Britannica

    Mining Mining Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on

  • Shaft sinking Wikipedia

    Shaft mining or shaft sinking is excavating a vertical or near-vertical tunnel from the top down, where there is initially no access to the bottom.. Shallow shafts, typically sunk for civil engineering projects differ greatly in execution method from deep shafts, typically sunk for mining projects.When the top of the excavation is the ground surface, it is referred to as a shaft; when the top

  • quarry | National Geographic Society

    Quarrying material for use in building materials was much more work. Stones had to be carried or dragged out of quarries manually. Stones could also be hauled with pulley systems involving ropes and moveable wooden tracks or sleds. This process often involved thousands of slaves and other workers. On Easter Island, for example, almost the entire community had to be involved in the quarrying

    Underground mines are the alternative to surface mines. Surface mines excavate from the top down, a method that can become inefficient at depths greater than about 200 feet (60 meters) [sources: Illinois Coal Association, De Beers].Undergrounds coal mines can drive 2,500 feet (750 meters) into the Earth and other types even deeper -- uranium mines can reach 6,500 feet, or 2 kilometers.
