摘　　要：介绍了一种适应缓倾斜中厚低价，且底板岩性不稳固的采矿方法；即“束状孔有底柱崩落采矿法”，并概括论述了该方法与其类似的“垂直平行密集束状孔落矿的有底柱崩落采矿法”的区别和各自的特点。A mining method-caving mining with filamentary hole and bottom column is introduced,which is suitable for the mines that are of low pitch,middle thickness,low value and unstable bottom rock property.And the contrast is made between the method and another method-caving mining with bottom column and parallel vertical concentrated filamentary hole.
