| 摘 要： | 安庆铜矿1号矿体中留有形态较为复杂的东部单铁矿体。对上述矿体分别采用大、深、中三种直径炮孔进行双阶段连续回采,并进行工业试验,分析采空区稳定性及主要技术、经济指标。结果表明,多直径炮孔联合采矿法适用于-460m以上东部地区单铁矿体,为矿山未来持续高产、稳产提供了技术保证。

| Abstract: | The eastern iron district is remained in the No.1 orebody of Anqing Copper Mine with complex shapes.Double stage continuous stoping is used to the orebody respectively with large,deep and middle blastholes.Meanwhile,the industrial tests are carried out and the stability of mined-out areas and the main technical and economic index are analyzed.It is indicated that the multi-diameter blastholes combined mining method is suitable for the orebody in the eastern iron district above-460 m,and it provides technical assurance for future sustainable high yield and stable yield of mine. |

| Keywords: | iron orebody multi-diameter blastholes stope stability |
