The Application Of RS In Shanxi Datong Coalfield Geologic Hazard Investigation

Datong coalfield geologic hazard remote sensing inquisition is the remote sensing technique in the geologic hazard of again an application. The coal profession is the our country national economy to pay one of the prism industry, but the development of the mineral resources, especially not reasonable development,make use of, break the equilibrium of the mineral mountain system series originality, the F brings pollution to the mineral mountain and its surroundings environment and induct various geologic hazards, break ecosystem environment. More and more outstanding environment problem not only threaten to the people the life safety, and serious check and supervision the development of the national economy.The geologic hazards such as avalanche,slope slide and debris flow etc.s are turning worse with the development of the mineral resources.Our country makes use of the remote sensing technique to open the exhibition geologic hazard to investigate although start to compare with night,, make progress to compare quickly .Made use of the SPOT remote sensing data of 10 meters resolution and the ERS-1/2 radar image, imagery data of 30 meters resolution to carry on analysis to investigate to the geologic hazard of the coalfield area in Datong the geologic hazard the inquisition.We pass to carry on the solution that the solution translated to tally up the slice to translate a method to reach agreement to translate marking to the spot remote sensing picture, carrying on the detailed inquisition research analysis to the geologic hazards, such as avalanche,slope slide and debris flow...etc.;We made use of the mining subsidence problem that the synthetic aperture radar, SAR interference measure(the Interferometry Synthetic Aperture Radar) the principle folio district to carry on a research, following the latest remote sensing technique at home and abroad in following to carry on with the traditional optical remote sensing technique means Datong a coalfield to mine crack,solid waste to press to have wait foundation of geologic environment inquisition and evaluation, working hard to capture the remote sensing technique to develop of make a little bit high, adopts the interference synthetic aperture radar, SAR technique(InSAR) to carry on a coalfield to expect the mining subsidence geologic environment more to investigate and evaluate greatly and together for the very first time in the domestic.This thesis adoption open country investigate with indoor analysis,the evaluation combine together,the normal regulations technique means and new technique means combine together,point the inquisition combine together with general inquisition of method, usage environmental geology etc. many the theories and the technique means of the academics, to open country sampling result,indoor test result and area inside have already have of the research result carried on comprehensive analysis and summary, according to item design of the technique route and workload, to work area of the geologic environment present condition carried on system inquisition and evaluation.
