Abstract：In surveying and mapping science,during or after the exploitation of the underground resources,in order to do better on monitoring and studying the law of internal rock strata and surface subsidence,in addition to monitor the displacement of the surface and internal layers by using conventional measuring instrument,and we can also use the professional software of geotechnical engineering for simulation,analysis and calcula-tion.This paper analysed the measured data of the surface movement deformation characteristics by using the finite element analysis software FLAC,and analyzed the destruction rule of surface movement for special mining under the condition of large angle and reverse fault,put forward the development trend of the surface and sur-rounding rock’s deformation under that condition.The movement and deformation conclusion of the internal rock and the fault outcrop,provides guidance for the observation points and the lines’layout,which is a bene-ficial supplement to the observation of the earth's surface and surrounding rock,and at the same time,provides the reliable basis for the Study of coal mining technology under water body,building and rail,and on karst wa-ter body.
