Original scientific paper Mining near the fault structure can easily lead to the fault activity and induce serious geological disasters, posing a serious threat to coal mine safety production. To reveal the surrounding rock activity characteristics induced by near-fault mining, taking Qixing Coal Mine in China as the engineering background, the contrastive analysis of the microseismic events in...

Sungun Copper Mine is located in an area with a high level of seismic hazard. Most recently, the Ahar-Varzeqan earthquake with a magnitude of 6.2 on Richter scale occurred on August 11, 2012; at a distance about 40 kilometers away from the mine. Nevertheless, the seismic stability of the final pit wall has not been comprehensively reviewed. In this research, the southwestern wall of the final p...

Fundamental understanding of the goaf gas distribution in a gassy coal mine is necessary for developing effective goaf gas drainage strategies in the longwall coal mine. The goaf gas was subjected to the surface and body forces that were classified depending upon whether they acted on the surface area or the volume of the gas element. Of these forces, the body forces were more predominant in di...

The Boundary Element Method has been applied to calculate stress distribution and stability of underground mines for disposal of chemical waste. A case similar to the Stripa mine in Sweden has been considered. The rock mass was granite, with major fracture zones represented by three families of planes mutually orthogonal and 100 meters distant from each other. The pre and post processor GiD [3]...

Several coastal rocky shores in northern Chile have been affected by the discharges of copper mine tailings. The present study aims to analyze the chemical speciation of heavy metals in relation to the diversity of sessile species in the rocky intertidal benthic community on the northern Chilean coast, which is influenced by the presence of copper mine tailings. In particular, the chemical form...

In this study, soil samples were collected from a large-scale open-cast coal mine area in Inner Mongolia, China. Arsenic (As), cadmium (Cd), beryllium (Be) and nickel (Ni) in soil samples were detected using novel collision/reaction cell technology (CCT) with inductively-coupled plasma mass spectrometry (ICP-MS; collectively ICP-CCT-MS) after closed-vessel microwave digestion. Human health risk...

A new type of cosmic-ray experiment is under construction in the Pyhäsalmi mine in the underground laboratory of the University of Oulu, Finland. It aims to study the composition of cosmic rays at and above the knee region. The experiment, called EMMA, will cover approximately 150 m of detector area. The array is capable of measuring the multiplicity and the lateral distribution of underground ...

In Mediterranean areas, river systems are key for maintaining regional biodiversity by providing a high diversity of habitats. We studied bird community recovery for 9 years (2001 – 2009) during landscape restoration and Guadiamar Green Corridor establishment in the area affected by the Aznalcó llar mine spill (SW Spain, 1998). One year following plant restoration (3 years after the spill), val...
