分层进路挑顶崩矿回采工艺及其应用

针对围岩不稳固的急倾斜薄矿体的开采，在吸收浅孔留矿法与分段崩落法优点的同时，加以改进，使演变成分层进路挑顶崩矿回采工艺，并大胆应用于生产实际中，取得了良好的技术经济效果，为急倾斜薄矿体的回采工艺作了有益的尝试。

Slice Drift Stoping with Roof Cut Caving and Its Application

Aimed at mining the steep thin orebody whose host rock was unstable, based on incorporating the advantages of short-hole shrinkage mining and sublevel caving and modifying this two mining method, the slice drift stoping with roof cut caving was designed, and was used in mining production boldly, with good technical-economical results. This is a beneficial trial to mine the steep thin orebody.
