| 摘 要： | 依据自然支护原理针对云驾岭铁矿确定的开采网目，应用“采矿方法数据库”探讨了云驾铁矿村庄下开采的具体采矿方案，提出了普通房柱法，预控顶房柱法，大矿柱底盘漏斗采矿法等采矿方案。矿块矿石回采率达５０％多，贫化率６％左右。为建筑物下采矿开辟了新的途经。

| Abstract: | This paper,based upon the principle of self-supporting,puts forward rational ore block size suited to Yunjialing iron Mine After that,the database of mining methods has application ingoing further into the concrete mining plans used in the mine,such as the general room-and-pillar-mining, the room-and-pillar-mining with precontrolling roof and the footwall chute open stopping with large pillars. Ore block extractions,more than 50%,and the rate of ore dilution,about 6%', are obtained. And it opens up a new way to mining under towns. |
