Combined mining is a technique for analyzing object relations and pattern relations, and for extracting and constructing actionable complex knowledge (patterns or exceptions) in complex situations. Although combined patterns can be built within a single method, such as combined sequential patterns by aggregating relevant frequent sequences, this knowledge is composed of multiple constituent com...

In Sangan iron mine nearly two million tons of low-grade iron ore has been extracted and deposited in the mining site and currently no action is made on them. On the other hand, the mining site is located in the semi-arid region and wet processing has been restricted due to water shortage. In this research, the upgradation of Sangan low-grade iron ore from mine B has been performed by dry low-i...

the uncontrolled spread of illegal artisanal small-scale gold mining (asm), popularly termed “galamsey” in ghana, has, for decades, impacted adversely upon water bodies, soils, wildlife, human health, and safety. a lack of understanding, however, of the types of galamsey, their operational attributes, and their relative impacts has unfortunately hindered an effective policy response despite num...

background: the workers of mines, during a working day, are exposed to stress and psychological pressure that certainly affect the efficiency of their work. this study aimed to determine the level of stress, anxiety, and depression in workers of one copper mine in kerman province, iran. materials and methods: in this cross-sectional study, 250 workers of the operation unit of one copper mine in...

During the past years the rapid and chaotic growth in the size and use of the World Wide Web continuously creates new great challenges and needs. Browsing can be improved and expedited by taking users' preferences in account, which results into personalization of web pages. In brief, web personalization can be defined as any action that customizes the information or services provided by a websi...

Equipment-induced vibration is widely recognized as a health hazard. It is a physical stressor to which many people are exposed at workplace. Mining industry is no exception. In spite of extensive research undertaken in the developed countries, information on the magnitude of the problem in India is not available. An estimated 1 million workers were engaged in the Indian mining industry in the ...

Original scientific paper With the increase in mining depths and the occurrence of worsening conditions, deep, large-scale and rapid mining may lead to more complicated dynamic features for tunnels, making them vulnerable to dynamic disasters such as rock bursts and coal/gas outbursts with subsequent heavy damage and casualties. A three-dimensional structural mechanics model for deep stopes was...

One of the most important steps involved in mining operations is to select an appropriate extraction method for mine resources. After choosing the extraction method, it is usually impossible to replace it with another one because it may be so expensive that implementation of the entire project could be economically impossible. Choosing a mining method depends on the geological and geometrical c...

Tropical forests are among the most diverse ecosystems in world, completed by huge biodiversity. An expansion natural resource extraction through open-pit mining activities leads to increasing land and tropical forest degradation. Proper science-based practices needed as an effort reclaim their function. This paper summarizes existing practice of coal mining, covering regulatory aspects reclama...
