开采沉陷中的抽样定理及其应用

The sampling theorem and its application in mining subsidence

根据数字处理中的数学原理，提出了开采沉陷中的抽样定理。以此为基础，导出了地表移动观测站的合理点间距ｒ·其值为Ｈ（５ｔ），获得了以离散的地表移动观测值或预计值，恢复其连续性的地表移动变形值的计算公式。并以计算实例，给出了其计算方法。

This paper proposes the sampling theorem in mining subsidence according to the mathematical principle in data processing. Based on the sampling theorem, the reasonable distances between two Doints of observation station of ground movement are induced, and the formulae for calculating the continuous movement and deformation are gained on the basis of those dispersed points on ground surface. Then the calculating method is introduced in a ca.e.
