Development Of Solid Mineral Deposits
In the early 1970s, over 11 billion tons of solid minerals, about 3 billion tons of oil and about 1,000 billion tons of oil were produced annually. 3 natural gas. The growth of the world mining industry is at least 4 to 5 per cent per year; some 15 to 18 years of mining is doubled. The value of energy raw materials is 72 per cent, ore is 21 per cent, non-oil is 7 per cent.
The world produces about 60 per cent of metal ores, 85 per cent of non-metallic ores, 100 per cent Minerals and about 35% of coal. Underground mining is used for minerals that are deep.
Characteristics of solid mineral development: construction of high-produced mining enterprises (per yearly tens of million tons of minerals, mines and mines - several million tons); low-value deposits; integrated mining in mining (e.g., use of excavated breeds for the construction industry); transition to high depths (for careers, hundreds) m for mines - several km); implementation (on the basis of integrated mechanization and automation) of cyclical and terminal work arrangements; improvement of production and safety conditions; restoration of land and subsoil that have been disrupted by mining. In the development of oil and gas deposits, new ways are being introduced to influence productive plastics to improve the extraction of minerals from the subsoil, automated mining systems.
