Geotechnical Properties of Mine Fill
Mine fill is the material placed underground to fill the voids created by mining excavations. It provides overall large scale ground stabilization while allowing localized pillar recovery. In addition to providing a working floor or back, mine fill has the potential to reduce subsidence and minimize dilution. Mine fill is essential to cut and fill, benching and sublevel stoping mining methods. ...
متن کاملPreventing acid mine drainage from mine tailings
Mining activity always has high impact on its surroundings, being waste deposition the cause of multiple and complex problems to the environment. One of them is Acid Mine Drainage (AMD), causing acid water percolation through large areas in the mine site. Portugal was a prosper tungsten producer from the beginning of the XX century, having its apogee during World War II. Nowadays there are mill...
متن کاملImpact of mine tailings on surrounding soils: Case study of Draa Lasfar mine, Marrakech- Morocco
The present study represents a first insight into the Draa Lasfar min (Marrakech - Morocco) to assess the degree of polymetallic pollution caused by anthropogenic activities (like mine extraction) and consequently the possible diffusion of heavy metals and to predict the risk of their mobility in the surroundings of the mine area. The edaphologic parameters pH and electrical conductivity (EC) w...
متن کاملAccelerated weathering of biosolid-amended copper mine tailings.
Application of municipal biosolids to mine tailings can enhance revegetation success, but may cause adverse environmental impacts, such as increased leaching of NO3- and metals to ground water. Kinetic weathering cells were used to simulate geochemical weathering to determine the effects of biosolid amendment on (i) pH of leachate and tailings, (ii) leaching of NO3- and SO4(2-), (iii) leaching ...
متن کاملReview of Ecological Restoration Technology for Mine Tailings in China
Article history: Received: 11.11.2014. Received in revised form: 4.2.2015. Accepted: 6.2.2015. The disposal of mine tailings is identified as one source of an environmental impact finally resulting in a typically degraded ecosystem. It can easily cause air and water pollution and is a source of man-made mudslides with high-potential socioeconomic-energy impacts. Pollution control and ecological...
