Abstract Numerical simulation approaches have been widely applied to study mining induced subsidence, and they are potential methods the flooding uplift for abandoned mines. This paper gives an overview about different numerical simulate by underground mines, including three hydraulic conditions, considering both unconfined confined water conditions. Four basic schemes using 1-dimensional rock ...

Concentrations of total Hg, Hg (II), and methylmercury were measured in stream-sediment, stream-water, and fish collected downstream from abandoned mercury mines in southwestern Alaska to evaluate environmental effects to surrounding ecosystems. These mines are found in a broad belt covering several tens of thousands of square kilometers, primarily in the Kuskokwim River basin. Mercury ore is d...

to legislative requirements, being merely governed by insufficient environmental regulations under the Mines and Works Act 27 (MWA) (Swart, 2003). In 1981 the Chamber of Mines (COM) published a document titled ‘The rehabilitation of land disturbed by surface coal mining’, which constituted the first notable contribution to environmental protection. This guideline was later referenced in the Min...
