In the high groundwater table mine areas in China's eastern, such as YanZhou Mining Group, since the rapid development of coal industry, and especially the mining technique of fully-mechanized top-coal caving mining have been used widely, the surface deformation and subsidence becomes more tempestuous and rapider. With the great surface deformation, the rapid deformation of the leveling control network created newly is also resulted. Therefore to establish a high precise altitude datum in dynamic deformation mine areas is the one of the key problems to be settled urgently. In the paper the theory of altitude datum establishment with GPS technique in dynamic deformation areas due to mining is inquired into. Finally a case is given to prove.

In the plain mining area with a high ground-water table in eastern China, with the rapid development of coal industry. Especially when the fully-mechanized top-coal caving mining is adopted, the great surface deformation is resulted. Meanwhile, a great amount of groundwater is being extracted, which causes the leveling control network lose its functions quickly. In order to maintain the safe production, it is a fundamental measure for providing reliable datum to construct a scientific deformation monitoring system. In this paper, the theory and method of high precision deformation monitoring system with GPS geodetic technique in about 1000km2 mining area are studied. And it focuses on the scheme of deformation monitoring system with GPS in dynamic deforming area, the index system of data quality control, and data analysis model. Finally a case about deformation monitoring is introduced and some discussions are included.
