Application of satellite radar interferometry (PSInSAR) in analysis of secondary surface deformations in mining areas. Case studies from Czech Republic and Poland [PDF]
Secondary deformations are ground movements occurring in areas of ceased underground mining. These are associated with delayed readjustment of rock mass resulting in subsidence, discontinuous deformations (sinks, cracks, etc.) due to destruction of ...

Annals of Coal Mining and the Coal Trade [PDF]
IN a former volume (noticed in NATURE, vol. lix. p. 337) the author carried his annals of coal I mining down to the period of the Select Committee of the House of Commons on Accidents in Mines in 1834. He now continues the subject to the passing of the Coal Mines Inspection Act of 1850, and to the establishment of the Royal School of Mines. This volume,
