中文摘要:
      论述了崩落法开采急倾斜矿床地表移动不同于煤矿地表移动的宏观破坏特征、机制与规律、变形预计方法 ,指出了关键在于前者属构造应力型矿山开挖卸载 ,后者属自重应力型矿山开挖卸载。此构造应力型矿山地表移动规律与变形预计方法已成功应用于某矿山开采设计 ;其变形预计工程处理方法与原则 ,可广泛用于水平向构造应力显著的崩落法开采急倾斜赋存的金属、煤矿床 ;它成为有别于煤矿地表移动的一大新类别。
英文摘要:
      The characteristics,mechanism and rule of macroscopic destroy and the deformation prediction method for surface movement with mining steep veins by caving method is different from that of colliery.The former belongs to the tectonic-stress typical opening unstressing while the latter belongs to the gravity-stress typical opening unstressing.In this paper,the characteristics,the mechanism and rule of macroscopic destroy are briefly discussed and new method used for the prediction of deformation for this kind of veins is presented.The method has been successfully used for the exploitation design in a certain mine.The method and its principle can be used in steep metal veins,which are mined by caving method and have remarkable horizontal tectonic stress.It has become a new sort of surface movement prediction different from that of colliery.
