Flooding, mines

Effluents from flooded mines are characterised by a more or less constant flow rate but a characteristic decrease of the contaminant load over time, resulting from the initial flush at the time of flooding and a prolonged tail due to the dilution of the mine water body by infiltration water inflow (which is partly overlain by dissolution, adsorption and precipitation processes within the mine)... 

Table 3 illustrates the composition of four mine waters. It will be noted that sulphide ore mines tend to generate more aggressive mine water than coal mines, and that recently flooded mines tend to generate poorer water qualities than long-... 

In most flooded mine systems (including all the case studies mentioned below), the ultimate... 

For heat pumps based on flooded mine systems, where the heat abstracted is replenished seasonally by inputs from solar radiation and geothermal gradient, the longevity of the reservoir is, in principle, limitless. The sustainability of the operation will only be limited by the durability of the infrastructure (e.g., biofouling, clogging or physical instability of boreholes, longevity of collector coils).

Between pH 0.5 to 3.0, when Fe is the oxidant and oxygen is absent (conditions that might be expected in an acid groundwater or in flooded-mine pools), the rate equation is... 

In the upper and middle course of river systems, sediments are affected by contamination sources such as wastewater, mine water from flooded mines and atmospheric deposition. Sediments are intermittently mobilized and deposited. During floods. 

A similar intentionally flooded mine is operated at the Moab Cane Creek, Utah (U.S.A.) plant. The potash brine is solar evaporated to crystallize sylvinite. The sylvinite is dry harvested and sent to a processing plant for conventional flotation. 

Drainage. Some mines are located beneath subsurface streams, or the coal seams may be aquifers. These mines may become flooded if not continually pumped. In Peimsylvania anthracite mines as much as 30 tons of water maybe pumped for each ton of coal mined (94). 

Soil with elevated content of these elements occurs along the Sacramento River in both levee and adjacent flood basin settings. We interpret that transport of sediment impacted by large metal sulfide mines located in the Klamath Mountains at the north end of the Valley has caused this pattern.
