In , a new laboratory investigation was started to study the causes, behavior, and control of mine fires.
Of particular importance and concern to the global coal mining industry is acid mine drainage (AMD)  and . This is caused by the oxidation of pyritic sulphur due to exposure of pyrite (FeS. Of the three primary sources of stream degradation by acid mine drainage--underground mines, coal refuse disposal sites, and surface mines--the latter source has been studied most intensively. This U.S. Bureau of Mines paper presents two case studies to illustrate contaminant formation and discharge in surface mine settings.

[National Coal Association.; Bituminous Coal Research, Inc.; United States. Federal Power Commission.;]. This paper first introduces the principle of testing the main drainage pump efficiency in coal mine using thermodynamic theories, then analyzes the energy transformation during the process of.
Acid mine drainage, acid and metalliferous drainage (AMD), or acid rock drainage (ARD) is the outflow of acidic water from metal mines or coal mines. Acid rock drainage occurs naturally within some environments as part of the rock weathering process but is exacerbated by large-scale earth disturbances characteristic of mining and other large construction activities, usually within rocks.

Acid mine drainage (AMD) is a prominent threat to water quality in many of the world's mining districts as it can severely degrade both the biological community and physical habitat of receiving. According to the statistics, the discharged amount of coal mine drainage is × m3 inand the utilized amount of coal mine drainage is × m3 in China (Wang ).
It is an effective way to solve the problems of water scarcity in most coal mining areas by treating mine drainage as process water and domestic water.

Government Printing Office, Washington, D.C. - Price $ The task of this committee was to broadly examine coal research, technology, and resource assessments, recognizing that they are essential components of an integrated roadmap for our nation’s future energy intent of this analysis was to allow policy makers to gauge the success of past research activities, gain a clearer understanding of the research presently being undertaken.
Third Symposium on Coal Mine Drainage Research, Mellon Institute, Pittsburgh, Pennsylvania, 12 CHAPTER 3 CHEMICAL TREATMENT Introduction The chemical treatment of acid mine drainage has involved the use of practi- cally every available neutralizing agent.
