this study investigated the functions, types and frequencies of code switching in the teachers and students discourse in elt classrooms. to this end, the participants of this study including two groups of teachers and students were selected. the first group of participants were two efl teachers teaching general english courses (at two different levels of proficiency) in an institutional program...
In order to sustainably use coal resources and reduce mine accidents, the stability evaluation of roadway roofs is particularly important. The existing methods roof control application are greatly disjointed, relationship between early warning ignored, an intelligent calculation system lacking. Based on successful roof-cutting non-pillar mining method in various engineering geology conditions, ...

This study involves seismic monitoring of a deep coal mine. The purpose is to examine the processes responsible for induced seismicity. A seismic network consisting of five threecomponent short-period seismometers located above the mine recorded the seismic data. The events discussed here occurred from March 1, 2009 until April 7, 2011 during the mining of three longwall panels and the data was...
prioritizing the reclamation criteria during mines closure (golgohar, sangan, chadormalu iron mines)
introduction development of natural resources and mining activities are prerequisite for economic and industrial growth in many countries. in many cases, such mining areas lie within residential or agricultural lands or natural habitats intensifying the contradiction between land use and environmental protection. different components of mining activities including exploration, extraction and pr...
It is our great honor to edit this special issue of Environmental Geochemistry and Health (EGAH), especially with the special theme of mine reclamation and suitable management for heavy metals. This issue has been made up with the extended works of oral or poster presentations that were given at the 2009 International Symposium on Mine Reclamation held cooperatively by the Korea Mine Reclamatio...
This paper discusses the optimization of the mine design and scheduling as it is applied at Anglo Platinum and more specifically, the rationale for and use of the Anglo Platinum Mine Optimisation Tool (APMOT), which has been jointly developed between Anglo Platinum and Cyest over the past four years. Mine optimization is an inherently iterative process since all facets of mine design and schedu...
