摘　　要：随着马坑铁矿年生产能力的提高,原有的浅孔留矿法及分段空场法已无法满足安全、高效的生产要求,为提高单个矿房的生产能力,减少作业面,降低安全管理成本,试验了大直径垂直深孔阶段矿房(VCR)法,并取得了成功。With the increase of annual production capacity of makeng iron mine,the original Shallow-hole shrinkage mining method and sublevel open stop mining have been unable to meet the requirements of safe and efficient production.In order to improve the production capacity of a single ore room,reduce the operating surface and management cost,vcr mining method was tested and succeeded.
