Water Control in Underground Mines – Grouting or Drainage?
mine water control programs can substantially improve mining conditions by increasing the efficiency of rubber-tired vehicles, creating a safer environment by working in dry, instead wet conditions, and, therefore, decrease the cost of operations. Considerable cost savings can be realized in a mine with an adequate water control system.
Gypsum | Indiana Geological & Water Survey
Deep below the rugged surface of Indiana's Martin County people work in two underground mines to extract and process an unusual mineral resource gypsum. Gypsum (CaSO4*2H2O) is a soft, water soluble mineral that is processed to make critical building materials especially wallboard. Gypsum is mostly massive (Fig. 1A) but also forms silky satin spar (Fig. 1B).Онлайн-запрос
Mining water from gypsum, International Journal of Global
Jan 01, 2008· Water resources in the world are scarce and unevenly distributed. In deserts, the only source of drinking water is groundwater, often saline and of poor quality. In many places, the groundwater levels have dropped dangerously due to overexploitation. Gypsum deposits, that are very common in deserts, are a potential source of drinking water, a fact that is realised by very few people. GypsumОнлайн-запрос
Gypsum Mines N Minerals
Gypsum is an evaporite mineral most commonly found in layered sedimentary deposits in association with halite, anhydrite, sulfur, calcite and dolomite. Gypsum (CaSO4.2H2O) is very similar to Anhydrite (CaSO4). The chemical difference is that gypsum contains two waters and anhydrite is without water. Gypsum is the most common sulfate mineral.Онлайн-запрос
