Mining-induced geo-hazards with environmental

2014-4-24  Dongchuan copper mine is located in Dongchuan District in Kunming City, which is one of the regions with the highest debris flows in China (Mo et al. 2006; Du et al. 2010). There are hundreds of debris flow valleys around the Dongchuan copper mining area. Long-term copper mining aggravates the scale and the frequency of occurrence of debris flows.

Assessment of eco-hazard of copper-nickel ore mining

2014-12-4  The authors examine oxidation of sulfide minerals in mine waste and the associated ecological problems. The highest environmental hazard is produced by fine-dispersed mill tailings, especially where sulfide content is comparable with nonmetal content of low-chemical activity. In terms of some production waste accumulations in Murmansk Region, it is shown that the eco-hazard source
