摘　　要：凡口铅锌矿在过去几十年里,由于采矿设备的限制,顶底柱残采的采矿工艺较落后,在回采过程中不但采矿效率低,且安全风险大,因此大量顶底柱未能得到及时回采.最近几年通过新设备的引进,采矿工艺的更新,加快了对顶底柱的回采.然而新的回采工艺也存在不少问题,需要进一步分析研究进行完善.In the past decades, due to the limitation of mining equipment, crown and sill pillar orebody mining technologywas relatively backward for Fankou lead-zinc min, the efficiency was not only low in the process of stoping mining, but alsothe safety risk was high, so, a large number of crown and sill pillar orebody could not be stoped duly. In recent years, itspeeds up the stoping of crown and sill pillar orebody through the introduction of new equipment and mining technology up-dating. However the new stoping process has many problems which need to be further analyzed and studied.
