The history of mining disasters includes cases of subsidence and collapse into workings, and also a number of inrushes into underground mines, where deficiencies in surveying, or in maintenance and interpretation of plans, were prime factors. The most recent incident in Australia was at the Gretley Colliery in NSW, in 1996. The most recent such incident in the USA was at the Quecreek Mine in So...
Rock burst is the most attractive and hot research area in geomechanics, mining, and civil engineering due to the increasing depth of mines and construction of deep underground structures. It has also been a severe problem in ground control measures in the last few decades. Many studies have been done by different researchers in order to minimize the hazards of rock burst and to provide a safe ...
Underground mining activities lead to ground movements at the earth surface. An area-wide monitoring and the documentation of mining induced influences are required by the mining authorities. Work done in the past confirmed a significant potential of SAR interferometric methods to contribute information to such monitoring. Nevertheless, in spite of advanced SAR interferometric processing techni...
