降低缓倾斜矿体矿石回采贫化率的矿块布置形式研究

摘要

Based on an introduction of block arrangement for mining gently-dipping orebody, effect of block arrangement on the dilution rate of ore stopping method was analyzed. Then, advantages and disadvantages of two kinds of block arrangement in mining gently-dipping orebody for the stoping dilute rate were analyzed in terms of technique and economy, which might be of guidance and reference for future practice in selecting block arrangement for mining such kind of gently-dipping ore body.%介绍了缓倾斜矿体矿块布置形式,分析了矿块布置形式对矿石回采贫化率的影响,并从技术经济方面比较了缓倾斜矿体中2种矿块布置形式矿石回采贫化率指标的优劣,可为缓倾斜矿体矿块布置形式的选择提供实践指导与借鉴.
