Mine Closure Considerations in arid and semi-arid Areas

with mining development and closure in arid and semi-arid areas, these include: o Low population density prior to mining. o Water supply. o The effects of extreme climatic events with respect to water balance and surface water management. o Infiltration to mining components after closure and the potential development of poor quality leachate. o Long-term land use: typically difficult to find ...

Mining and energy - Arid Areas Research and Development

It is especially in the arid areas of South Africa where diamond mining has been prominent. In line with the international experience, mining closures have also been prominent in South Africa during the past 20 years. These closures have been the result of depleting resources on the one hand, as well as more international competition and mining competitiveness on the other. Although there is ...

Mining in Hot, Arid Areas - Curriculum Press

There is great potential for the development of mineral resources in hot, arid areas. Oil and gas in the Middle East, copper in Chile, southwest USA and Australia, and uranium mining in Australia illustrate the potential riches that occur in hot, arid areas. Exploitation may be difficult because many of these areas are remote, and investment in transport is expensive. In addition, housing and ...

13/11/2017  Just like vegetation, semi-arid areas do not host a lot of animals. Usually, only animals that are adapted to grassland ecosystem are found in the semi-arid areas, meaning only animals such as bison, antelopes, and zebras among other ungulates can be found in the region. Large predators such as lion, jackals, and wolves may also be found in the semi-arid areas depending on the continent in ...

Unlike hot semi-arid climates, areas with cold semi-arid climates tend to have cold winters. These areas usually see some snowfall during the winter, though snowfall is much lower than at locations at similar latitudes with more humid climates. Areas featuring cold semi-arid climates tend to have higher elevations than areas with hot semi-arid climates, and tend to feature major temperature ...

Water Conservation in Arid and Semi-Arid Regions

Water resources in arid and semi-arid areas are very scarce due to the low rainfall and high evaporation. This complicates the supply of water for domestic, industrial and agricultural uses. Water managers in arid areas must therefore have a very clear understanding of the constraints and opportunities of the available water resource base. This will facilitate the development of an

Effects of underground mining on vegetation and ...

30/08/2018  A rapid increase in underground mining in a semi-arid area of China has led to serious concerns about the health of vegetation overlying these coal seams. However, there have been no empirical studies to illustrate the response and persistence of surface vegetation in these underground mining areas. A combination of field assessments with remote sensing was used to examine

The overall’ conclusion of this study is that, in arid and semi-arid zones, runoff from small areas such as micro-catchments is an important potential source of water VI1 . for the establishment, development, and growth of trees. A supply of runoff water can make the difference between death and survival and between minimum development and good growth of trees. Especially in dry years, the ...
