A Study of Mine-Related Seismicity in a Deep Longwall Coal Mine
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...
متن کاملEvolution of seismicity at Kiruna Mine
Kiirunavaara (Kiruna) iron ore mine owned by LKAB (Sweden) is one of the largest underground mines. Mining started in 1898 as an open pit mine. In mid-1950, the mine started a transition to underground mining and passed to only underground mining in 1962. More substantial problems with seismicity started in 2007-2008 when the deepest mining level was 907 m (ca. 670 m below surface). By 2016, th...
متن کاملSatellite radar interferometry for mine subsidence monitoring
Australia is one of the world’s leading mineral resource extraction and exporting nations. Underground mining can cause ground surface displacement, which may in turn have serious impacts on the environment or man-built facilities. This paper describes the results of a study into the feasibility of surface subsidence (caused by underground coal mining) monitoring using differential interferomet...
متن کاملDifferential Radar Interferometry for Mine Subsidence Monitoring
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...
متن کاملAcid mine drainage and subsidence: effects of increased coal utilization.
The increases above 1975 levels for acid mine drainage and subsidence for the years 1985 and 2000 based on projections of current mining trends and the National Energy Plan are presented. No increases are projected for acid mine drainage from surface mines or waste since enforcement under present laws should control this problem. The increase in acid mine drainage from underground mines is proj...
