摘　　要：针对塔吉克斯坦北阿尔登-托普坎铅锌矿区8-2中段1-2b上斜分层多空区复杂条件下1-2b矿体残矿的回采,采用中深孔爆破技术,利用底部采场空区作为自由面、底部采场形成的采准工程,研究出科学合理的回采措施并予以实施,解决了复杂多空区的安全隐患,实现了1-2b矿体残矿安全回收,所取得的经验可为今后类似情况的残矿回采提供参考。Aiming at the stoping of 1-2b residual ore and ore body under complex multi goaf area in the 8-2 middle section of the North Alden-Topkan Lead-Zinc Mining Area in Tajikistan,the medium deep hole blasting technology is carried out,using the bottom goaf as the free surface and bottom goaf to form a mining access route.The scientific and reasonable mining measures have solved the hidden danger of the complex multi goaf area and achieved the stoping residual ore of 1-2b Orebody,providing reference for residual ore stoping in similar situations in the future.
