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 ...
Opening new phosphorus mines Locations of new phosphorus deposits are mostly located in high-conflict regions around the globe such as Algeria, Iraq and Syria see the phosphorus problems page, where it will be difficult to establish new mines. The phosphorus deposits currently being mined will run out in the near future.
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.
Soil moisture content, total nitrogen, available phosphorus and exchangeable potassium were positively correlated whereas, Mn and bulk density were negatively correlated with age of overburden spoils at p 0.05.

phosphorus concentrations than those from the lower part. In all three coal-bearing formations, the amount data scatter within individual se.ams can be very pro- nounced. The range in average clean coal phosphorus concen- trations, 0.030 to 0.044 per cent, is smaller than the range.
The eutrophication of three small lakes in the aquatic zones at the Huainan coal mine subsidence areas, designated as east site ES, central site CS, and west site WS, were studied. Nutrient content, species, and nitrogen N to phosphorus P ratios were obtained through water quality analyses
Irrigation runoff from agriculture and specialty crops production remains a source of excess phosphorus P loading into aquatic systems. Iron hydroxide from coal mine drainage CMD was investigated in this study as an adsorbent for low-cost P removal from greenhouse and plant nursery runoff. The overall objectives of this study were to quantify the P sorption capacity, desorbability of P ...

Jan 15, 2021 In some key coal producer countries, like India, Australia, the United States, and Germany, surface mining accounts for 8090 of the total coal production Kholod et al., 2020, Wu et al., 2020. In spite of the high production of coal, surface mining inevitably results in complete obliteration of the ecosystem.
mining, especially opencast coal mining, damages the surface vegetation and soil and changes the hierarchical structure of natural soils. As a result, a series of soil quality degradation problems have appeared in Chinas coal mining areas, including heavy metal soil contamination, which is a major limiting factor affecting soil quality.

Jul 23, 2020 Coal mining activities result in large-scale soil degradation and ecosystem imbalances in many countries. Fertilization is an effective way to improve soil fertility and microbial activity. However, the effect of different fertilizers and remediation time on the subsided soil is not clear. The aim of this study is to explore the effects on soil fertility and the bacterial community.
