摘要
急倾斜矿床崩落法开采地表移动不同于煤矿地表移动的宏观破坏特性 ,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。构造应力型矿山地表移动的宏观破坏特征研究为掌握该类矿山的地表移动规律 。
The surface movement caused by caving mining of steeply inclined deposits is different from that of collieries. The former is the tectonic stress type mine's opening unloading and the latter the gravity stress typemine's opening unloading. The investigation of macroscopic destraction properties of the tectonic stress type mines aims at to understand the surface movement law of the type mines and laying a foundation for working out the countermeasures against it.
