Water supply

WATER SUPPLY within the mining craft (EN: water supply; DE: Wasserversorgung; FR: alimentation en eau; ES: suministro de agua; RU: водоснабжение) is the provision of the mining enterprises with the water. The water supply is necessary for the performance of the hydrotechnological processes for the excavation and transportation of the solid useful minerals (see the "Hydromechanization" article), for the extraction of the petroleum (see the "Water flooding" article), for the wet beneficiation of the useful minerals, for the hydraulic stowing works, for the dust suppression, for the extinguishing of the underground fires, and so on. At the hydraulic underground mines, hydromechanized open-pit mines, productive petroleum fields, and other mining enterprises, where such processes are among the major processes, they use the so-called recycling systems for the water supply (see the "Recycled water supply" article), and also the systems with the sequential usage of the water by several consumers. The water supply is performed on the account of the superficial waters from the exposed watercourses and water bodies (rivers, water reservoirs, lakes, seas), and also on the account of the underground waters, underground mine waters, and open-pit mine waters. The requirements for the quality of the water for the technical water supply of the mining enterprises are limited mostly using the indicators of the pH, hardness, and using the content of the salts and suspended particles; the drinking water supply within the USSR is regulated by the GOST 2874-73 standard (see also the "Water" article).
