摘　　要：为解决黄沙坪矿79#1-1矿体由于矿体含硫高、矿岩破碎不稳固、允许暴露面积小、矿山无胶结充填系统,因而开采困难的问题,进行中深孔成孔试验和孔底温度监测试验,在此基础上提出长锚索预护顶下分段凿岩阶段嗣后充填采矿法。文中介绍了该方法的特点、结构尺寸、采准切割与回采工艺。现场工业试验表明,该方法实现了矿体安全、高效的回采。79#1-1 ore-body of Huang-sha-ping mine is high in sulfur and with broken ore-body,small exposing area,and no consolidated fill system.These make it difficult to stope.Aiming at solving these problems,hole-forming and temperature tests of hole-bottom were performed.The sublevel rock drilling stage vacant place subsequent backfill mining method with pre-supported the roof by cables was adopted.The characteristic,structure size,quasi-cut mining and stopping technology of this method were introduced in detail.Industrial practice showed that the method is safe and efficient.
