本文所讨论的矿床类型特点是:矿体上盘围岩一般为中等稳固;矿体下盘围岩一般为稳固至不稳固;矿体倾角一般为25～45°左右;矿体厚度一般为2～4米左右;矿石一般由稳固至不稳固。从目前国内外矿山现状来看,对于此类矿床一般是试验和应用长壁崩落法、低分段崩落法或高分段崩落法以及其它充填法开采。当采用上述采矿方法时,归纳起来,主
The type of deposit discussed in this paper is that the surrounding rock of the ore body is generally moderately stable; the rock mass of the ore body is generally stable to unstable; the dip of the ore body is generally about 25-45 °; and the thickness of the ore body is generally 2 ~ 4 meters; ore generally from solid to unstable. From the current status of mines at home and abroad point of view, for such deposits generally test and application of longwall caving method, low caving or high caving method and other filling method mining. When using the above mining method, summed up, Lord
