为提高河东金矿的采矿生产能力，我们在河东金矿进行了新的采矿方法——预控顶分段空场尾砂充填采矿方法的研究。该采矿方法采用采场预控顶技术，中深孔爆破，铲运机出矿，尾砂充填。采场切割井用中深孔一次爆破技术，采场周边及上盘则采用光面爆破技术，确保采场稳定。为确保试验顺利进行，在采场进行了综合的护顶和护帮技术措施。

To increase the mining capacity of Hedong Gold Mine,study was made on a new mining method at the mine,that was tailings back-fill mining with roof presupporting and sublevel open stoping.The new method adopted roof presupporting,deep and medium hole blasting,LHD ore removal and tailings filling.One-time blasting of deep and medium holes was applied for the cut-through raise and smooth surface blasting was used for the stope periphery and upper wall to ensure the stope safety.To ensure a smooth test,comprehensive technical measures for roof and wall supporting were taken.
