摘要
基于削壁充填法工艺的特征,作者对地下开采薄矿脉及极薄矿脉直接计算贫化率的公式进行了研究和分析,并提出了削壁充填采矿法的更符合实际应用的贫化率计算公式,这不仅在技术上而且在经济上都具有一定的价值。
Based on the features of the mining technology of resue-and-filled sto-ping, the author has made a research and analysis on the formula for calculating dilution directly in the narrow and extreme narrow vein stopes underground, and presented a new formula more practical for calculating ore dilution in this method.
The author supposes that this research is of great significance not only in theoretical and technological fields but also in the respect on economic benefit.
