摘　　要：某矿在长期使用空场采矿法中形成了特大采空区,给矿山生产带来了安全隐患。针对这一难题,根据矿山实际的矿体赋存、开采技术经济条件以及空区特征,对空区下矿体回采方案进行了分析与研究,提出了空场嗣后充填采矿法和上向水平分层充填采矿法2种回采方案。考虑到矿山的实际情况,空场嗣后充填采矿法较优,但矿山空区情况已经不容乐观,应及时对空区进行充填处理。A large goaf has been formed in the mine due to the long times of the open field stoping,which brings safety hazard to the mine safety production.Aiming at this problem,this paper analyzes and studies the mining method of ore body under the empty area by considering the occurrence of ore body,the technical-economic conditions of mining and the characteristics of empty area and provides two mining schemes:Open field backfill method and backfilling and upward horizontal slicing and filling methods.Considering the actual situation of the mine,Open field backfill method is better.However the situation of the empty area of the mine is not optimistic,it is necessary to fill the empty area in time.

关 键 词：采空区 矿体回采 空场嗣后充填采矿法 采矿方法 回采工艺 充填
