摘要:

鑫泰矿业公司矿体为缓倾斜薄矿体,薄矿体回采主要以分采分出为主,对分采的判断依据和分采指标以往都采用传统经验判断法。为充分利用有限的矿石资源,以回采盈亏平衡技术经济分析法为出发点,针对薄矿体分采分出回采方案,通过对数据的综合分析,归纳总结,选择科学合理的回采技术指标,以获得利益最大化。该方法为矿山提高出矿品位,降低回采成本提供了依据,确保经济效益取得实效,达到可持续发展的目的。

Abstract:

The ore bodies of Xintai Mining Company are moderately inclined thin ore bodies and the extraction is dominated by separate mining and separate drawing.The judgment criteria of separate mining and index used to be based on empirical judgment method.In order to make full use of limited ore resources,balanced extraction profit and loss technical and economic analysis acts as the foundation.For the thin ore veins separate mining and separate drawing plan,the data are analyzed comprehensively and summarized,and reasonable extraction technical index are selected,to make maximum profits.The method can provide basis to improve drawn ore grade,lower extraction cost,and guarantee practical effect of economic benefits,attaining sustainable development.
