采矿区地层移动GPS动态监测数据的小波分析

WAVELET ANALYSIS OF GPS DYNAMIC OBSERVATIONS OF STRATIGRAPHIC DISPLACEMENT IN MINING AREA

地下煤炭资源的开采会引起岩层和地表移动。为研究开采引起的地形变规律 ,用小波理论对兖煤集团东滩煤矿的GPS动态变形监测资料进行多尺度一维分解、阈值选择和自动消噪等分析 ,提取了变形的主要因素 ,说明了小波分析的有效性和可行性。

The coal mining will bring about the deformation of rock formation and the earth's surface.To study the rule of the deformation, on the basis of Wavelet Analysis Theory (WAT) the dynamic deformation data of Dongtan mining is analyzed and some helpful results are obtained.It is demonstrated that the WAT is valid and reliable for studying the rule of the deformation of rock and the earth's surface.
