In the paper a detailed analysis of the dynamic response of a cooling tower shell to mining tremors originated from two main regions of mining activity in Poland (Upper Silesian Coal Basin and Legnica-Glogow Copper District) was presented. The representative time histories registered in the both regions were used as ground motion data in calculations of the dynamic response of the structure. It...

This paper uses data on the world’s copper mining industry to measure the impact on e¢ ciency of the adoption of the ISO 14001 environmental standard. Anecdotal and case study literature suggests that …rms are motivated to adopt this standard so as to achieve greater e¢ ciency through changes in operating procedures and processes. Using plant level panel data from 19922007 on most of the world’...

Mining of the world's second-largest nickel deposits in the area of Sudbury, Ontario, Canada, has caused acidification and metal saturation of some catchments. We conducted artificial stream studies in the years 2001 and 2002 to assess the effects of treated metal mine effluents (MMEs) from three different mining operations discharging to Junction Creek, Sudbury, on two fish species, creek chub...

An integrated approach including chemical speciation analyses and microalgal bioassays was used to assess the impact of copper from copper mining on a coastal area in Northern Chile. Dissolved copper ranged from <1 microg l(-1) at reference sites to 48 microgl(-1) at sites close to the mine discharge. Dissolved copper at sites closest to the discharge always exceeded seawater complexing capacit...

Chile has an economy strongly based on the exploitation of its natural resources. Copper mining represents the main export monetary income, employing thousands of people all along the country. The Chilean Copper Corporation (CODELCO), El Salvador branch, has been the primary mining company, but it will be ending most of its activities by 201 1 unless copper prices stay at their record levels. B...

The abundant natural resources can bring either positive or negative impact to the country’s economy depending on the macroeconomic policies. Mongolia has massive mineral resource dominated by coal, copper, and gold. The Government of Mongolia has started to implement a number of infrastructure projects to decrease the mining project’s cost burden caused from the country’s weak infrastructure. ...

AIMS In the last decades, the worldwide increase in copper wastes release by industrial activities like mining has driven environmental metal contents to toxic levels. For this reason, the study of the biological copper-resistance mechanisms in natural environments is important. Therefore, an appropriate molecular tool for the detection and tracking of copper-resistance genes was developed. M...

Mexico is characterized as a mining country since it the world’s main silver producer. During its extraction, wastewater (mining tailings) generated which contains cyanide and heavy metals. The purpose of this research was to determine whether bacterial consortium isolated from tailings dam can use source nitrogen carbon carry out biodegradation. study determined effects three physicochemical f...

With the continuous downward mining, more and attention has been paid to problem of slope stability under open-pit combined mining. Taking Zijinshan gold copper mining as an example, failure properties overlying rock mass different methods are studied by numerical simulation method, law is proposed. Combined with geological structure distribution 5-5 section influence stages, evaluated slip fie...

Mining and metallurgy have negative consequences for the environment [1-3] and lead to changes in geological [4] and climatic conditions [5]. Mining-metallurgy operations include the extraction, preparing of ores (crushing ore and flotation), processing of concentrates, and the disposal of waste rock and by-products. The main waste in mining and metallurgy are waste rocks, flotation tailings an...
