This document summarizes some of the environmental and safety issues associated with mining. It discusses how mining can modify habitats and landscapes, contaminate surface and groundwater, and produce high levels of residues. It also describes some of the health risks miners face from dust, heat, poor air quality, and water inundation. Major mining disasters that have occurred include explosions, collapses, and landslides which have caused many deaths over the years. One significant ecological disaster discussed was the 1998 toxic spill from a pyrite mine in Spain that contaminated local beaches and ecosystems.
Disasters and problems associated with mining
- 1. Disasters and problems associated with mining Marta Navarro Uriel Laura Ferrer Montañés
- 2. Introduction What is mining? Mining is the extraction of minerals, metals and other materials from earth. Mining of stone and metal has been done since pre-historic times. Minerals are a nonrenewable resource, and because of this, the life of mines is finite.
- 3. Mining around the world
- 4. Environmental impacts - Habitat modification. - Changes in topography and landscape. - Surface and groundwater contamination. - High levels of residues. - Fugitive dust emissions. - Changes in land - use and soil management. - Climate change considerations.
- 5. Work in the mines Agents Dust everywhere Air poor Temperature high Water inundation
- 6. In addition… - Human factors - Organization - Mining equipment machinery - Explosive and flammable chemicals - Climatology
- 7. Consequences Diseases Falls DISASTERS Explosions Collapses Landslides
- 8. Collapses 1997 – Tanzania: more than 1000 dead (gold). 2000 – Sierra Leone: 150 dead (diamond). 2006 – Tasmania: 14 escape. 2006 – Chile: 70 miners were trapped. 2010 – Chile: 33 miners were trapped, rescued.
- 9. Explosions - 1906 – France: worst disaster in Europe, 1099 dead. - 1913 – Wales: 439 dead. - 1942 – China: 1549 dead. - 1991 – China: 147 dead. - 1992 – Turquía: 267 dead. - 1994 – Filipinas: 119 dead. - 2000 – China: 162 dead. - 2002 – China: 164 dead. - 2004 – China: 148 y 166 dead - in 2 explosions.
- 10. Ecological disaster The Doñana Ecological Disaster, 1998, a toxic spill of acid waste rich in heavy metals from the processing of pyrite ore.
- 11. 1) Dam breaks and spillage of 5 million cubic meters. 2) Six kilometers from the park. 3) The contaminated water has arrived at the Guadalquivir mouth. The Malandar beach is affected by the spillage.
