摄影测量与金属矿地表移动监测

APPLICATION OF CLOSE-UP PHOTOGRAMMETRY TO OBSERVATION OF SURFACE MOVEMENTS IN METAL MINES

金属矿山岩层与地表移动有其自身特点。以塌陷为主的剧烈移动，不能用常规的大地测量方法监测移动全过程，只能借助于非接触性的测量手段。摄影测量作为一种三维遥感方法具有独特的优点。作者采用的解析方法具有灵活性和实用性，可在相关矿山中推广应用。文中还简要介绍了两个成功实例。

Ground movements in the metal mines differ from those occurring in coalmines. Photogrammetric measurements, as a three-dimension remote sensing technique,proved to be effective in observing the instable collapse areas。 Analysis and two examples ofapplication of the technique to surface subsidence observations show that the new analyticalmethod advanced by the present authOrs in this paper possesses notable advantages of flexi-bility and practicability。
