Jan 28, 2015 Underground mines use the room-and-pillar method, similar to coal mining. In 2013, phosphate rock was produced almost entirely from surface mines, with only one active underground mine in the world. Phosphate rock, when used in an untreated form, is not very soluble and provides little available phosphorus to plants, except in some moist acidic.

Use Of Bioluminescence For Monitoring Brown Coal Mine

Physicochemical parameters of brown coal mine waters differ between regions, i.e., mine waters can have variable concentrations of trace elements, total phosphorus, or conductivity [5]. In some areas, reactions causing low pH in the mine waters are linked to the problem of acid mine drainage (AMD), an additional environmental impact of mining [10].
