摘要
文章针对湖南宝山有色金属矿业有限责任公司北部铅锌矿区一种较普遍的矿体:急倾斜、走向狭长、围岩稳固,结合宝山矿北部铅锌矿区采矿实践,探索采用无底柱留矿法一次性空场事后干式充填采矿方法,最大限度地回收该类型矿体的矿产资源,提高采矿工效,提高该类型矿体的回采能力,实践证明效果显著。
Accoding to the similar geological characters of orebody： steeply- dipping,long- narrow strike and rigid rock,combining with the stoping practice of the northen part mining area, Baoshan Mine, the author put forward the method of waste - filling after overall open stoping without floor pillar. It has proved that this method can provide satisfied recovery, improved extraction efficiency and capacity.
