薄小矿体回采工艺优化

Deep displacement monitoring and result analysis of typical surrounding rock in deep mine rock roadway

薄小矿体资源利用一直是矿山企业生产中的难题,根据某矿山薄小矿体赋存条件,在满足开采原则的条件下,确定了无底柱小分段留矿法的采矿方法,并给出了主要技术参数,减小采切成本,为此类矿石资源开发提供借鉴经验。

The utilization of thin and small orebody resources has always been a difficult problem in mining enterprises.According to the occurrence condition of thin and small orebody in a mine,under the condition of satisfying the mining principle,the mining method without bottom column sublevel retaining method is determined,and the main technical parameters are given to reduce the mining and cutting cost and provide reference experience for the development of this kind of ore resources.
