Acidification is a common challenge in any respect mining websites during which oxygenated water is available in touch with sulfide minerals or different lowered sulfur compounds. a global Workshop used to be held in September 1995 on the division for Inland Water learn of the UFZ-Centre for Environmental examine in Magdeburg at the limnology of lakes created by way of open-cast lignite mining, emphasizing the customarily saw geogenic acidification after oxidation of pyrite. issues of curiosity have been case experiences at the limnology of acid lakes, e.g. bacteriologically stronger procedures with regards to heavy steel mobilization and acid new release, the ecology of sulfur-acidic lakes, and at the inorganic methods of acidification. moreover, ideas for the prevention and the abatement of acidification have been addressed together with the factors of acidification, and the choices for decreasing the output of acidified groundwater from overburden dumps, for acid regulate throughout the flooding of open-cast mines, and strength measures for brought about in situ organic neutralization. This quantity has 25 chapters together with a bankruptcy with result of staff discussions in regards to the subject matters pointed out above and additional difficulties that have been pointed out throughout the assembly. The monograph offers a baseline of the nation of technological know-how at the all over the world challenge of geogenic adidification of lakes following human mining actions, and the way to deal with this environmental problem.

Offshore Safety Management. Implementing a SEMS Program
2010 was once a defining yr for the offshore oil and gasoline within the usa. On April 20, 2010, the Deepwater Horizon (DWH) floating drilling rig suffered a catastrophic explosion and fireplace. 11 males died within the explosion ― 17 others have been injured. the fireplace, which burned for an afternoon and a part, ultimately despatched the complete rig to the ground of the ocean.
Designing for Human Reliability: Human Factors Engineering in the Oil, Gas, and Process Industries
Underestimates the level to which behaviour at paintings is encouraged via the layout of the operating atmosphere. Designing for Human Reliability argues that larger wisdom of the contribution of layout to human blunders can considerably improve HSE functionality and enhance go back on funding. Illustrated with many examples, Designing for Human Reliability explores why paintings platforms are designed and applied such that "design-induced human blunders" turns into more-or-less inevitable.

Sulphide minerals, such as pyrite and marcasite, are commonly associated with coal and most metal ores. Weathering and oxidation of these minerals take place in the host rocks and substrates of the lignite horizons when they are exposed to air. The release of the oxidation products, mainly acidity, iron and sulphate, is known as acid mine drainage (AMD) and has been the subject of intense research for decades (e. g. Singer and Stumm 1970; Lowsen 1982; Nordstrom 1982; van Berk 1987; Morrison et al.
5 d). In Lake Au and Lake Murner there is a decrease in the sulphate concentration in pore water below the sediment - water interface, while the ferrous iron concentration increases. Note that in the upper layers of the sediment of Lake Murner the concentration of ferrous iron is distinctly above the detection limit of l/lmolll. In Lake Murner the gradients of both species are steeper, indicating enhanced reductive processes relative to Lake Au (Fig. 5 a, b). Ferric iron is detectable at all depths, with concentrations slowly increasing from 140 /lmolll at the sediment - water interface to 500/lmolll at 13-cm depth (Fig.
