While the major wastes generated by mines are waste rock, tailings and overburden, the majority of emissions can be found in discharged mine water. As mine water accumulates when the water level overflows the depth of an open pit surface mine or an underground mine, the water must be pumped or drained out of the mine to ensure safety and stability..

The ratio between waste rock and ore production is called the stripping ratio. For example, a stripping ratio of 21 means that 2 tonnes of waste rock needs to be mined to mine 1 tonne of ore. Generally, an open pit mine has a higher stripping ratio than an underground mine. Waste rock is often stored close to the mine to minimize transports ....
