Monitoring underground coal mining - induced subsidence
Monitoring of mine subsidence by means of classical methods such as optical levelling or Global Positioning System (GPS) surveys can reveal deformations with sub-millimetre to subcentimetre precision for localised areas. However, to provide data on a reasonably dense two-dimensional (2D) benchmark grid are costly and time-consuming for all but the smallest areas. Moreover, a regular re-survey o...
متن کاملAssessment of radar interferometry performance for ground subsidence monitoring due to underground mining
This paper describes the results from the recently launched SAR satellites for the purpose of subsidence monitoring over underground coal mine sites in the state of New South Wales, Australia, using differential interferometric synthetic aperture radar (DInSAR) technique. The quality of the mine subsidence monitoring results is mainly constrained by noise due to the spatial and temporal decorre...
متن کاملDifferential Radar Interferometry and Its Application in Monitoring Underground Coal Mining-induced Subsidence
Ground subsidence due to underground coal mining threatens the safety of surface infrastructure such as buildings, roads, bridges, powerlines and telecommunication cables, and can cause environmental problems such as water pollution, cessation of stream flow, and so on. Monitoring the spatial distribution of surface deformation may be helpful for land-use planning, land reclamation, safety and ...
متن کاملIntegrated Space Geodetic Techniques for Monitoring Ground Subsidence Due to Underground Mining
Ground subsidence monitoring is of paramount importance in relation to the safety and efficiency of underground mining operations. Moreover, in established coal fields in eastern Australia, it has become harder and harder to select underground minesites which can avoid major engineering structures both on the surface and underground (highways, bridges, buildings, abandoned workings of old under...
