Mining Impact

Environmental Impact: Assessment

In view of the foregoing, the environmental impact of mining activity is the difference between the situation of the environment before carrying out the activity, and during or after mining. This impact assessment is to quantify these differences by conducting a multidisciplinary study that will seek to identify, predict and prevent the consequences or effects on the environment of mining.

An interesting point is that the impact study can be considered as a comparison between the actual situation of the area studied, and theoretical status of this area if it was not affected by mining activity.

The objectives of the environmental impact study would be:

1. Avoid possible errors caused environmental damage during the extraction process, which further correction could be costly, both in private perspective (costs transferable to companies) and from the social perspective (costs transferred to the Company).

2. Provide data to enter into business decisions the effects of development projects in the natural and social, always difficult to quantify and evaluate.

3. Provide integrated information on the impacts of our activity on the environment. Read the rest of this entry »

Classification of Environmental Impacts

The impact produced by mining from the environmental point of view can be classified in many different ways:

  • As a direct or indirect impact on the environment.
  • According to short or long term
  • As reversible or irreversible (human scale)
  • According to local or external
  • Avoid or inevitable

Moreover, according to environmental aspects that change can be

  • Actions that change the land use
  • Actions that involve the emission of pollutants (solids, liquids, gases and other: noise, air wave)
  • Actions that involve exploitation of resources (water)
  • Actions that involve the modification of the landscape (almost)
  • Actions that affect infrastructure
  • Actions that change the social, economic and cultural (economic impact). Read the rest of this entry »

The Environmental Impact of Mining

Mining, like most of the activities the man does for their livelihood, make changes in the natural environment, from the subtle to the clear account impacts on the environment in which they develop.

This leads us to define the concept of environmental impact of an activity: the difference in the environment between the time the activity begins, the time the activity takes place, and above all, the moment of completion.

These questions, which a few years ago were not perceived as a risk factor for the future of humanity, now viewed with great concern that is not always justified, since man is altering the environment since it has been able to do so, but certainly abuses in this field have led to growing awareness of the need to regulate these impacts. Either way, it should also be clear that the man needs the mineral resources today, and the need in the future. Another point to note is that mining is infinitely less powerful than other industrial activities, such as the development of civil works (visual impact, modifying the original media) and agriculture (massive use of chemical pesticides, fertilizers).

Thus, at present there are very strict rules about the impact that a mine can produce, including regulation of the composition of the liquid waste, emissions of dust, noise, landscape restoration, and so on., Which indeed often very challenging to meet the high economic cost, but undoubtedly have to be made to carry out the operation.
