摘要

爆破运动监测(BMM)系统是一种确定爆破过程中物料运动的新方法,以尽量减少矿石的损失、稀释和有时的误分类。2013年第一季度,AngloGold Ashanti Iduapriem (AAIL)矿山在2012年第一季度开始在Ajopa矿坑作业时遇到了协调问题,因此引入了BMM系统。自实行以来,对账已有所改善,但由于黄金价格不断下跌,所涉成本问题值得评估。因此,本文的主要目的是评估BMM系统对伊杜阿普利姆矿爆炸诱发移动的效益或其他方面。本研究包括对AAIL BMM系统的数据收集和分析,以及成本和效益分析。从BMM数据分析中可以看出,在水平方向上,爆破材料的底部翻动量大于顶部翻动量,而在垂直方向上则相反。从四个镜头的成本效益分析显示,有$753 835的效益,转化为650%的投资回报率。因此,BMM系统的使用对伊杜阿普利姆矿山产生了积极的财务影响。因此,建议继续使用该系统作为该矿的品位控制方法,特别是对于含有矿石的矿体。此外,建议为这项任务设立一个专门的小组,以提高效率。最后,建议在探测仪器中增加高精度GPS,使爆破前和爆破后BMM点的测量更加方便和快捷。关键词:爆破运动监测系统,矿石损失,贫化,误分级,和解

Control of Ore Loss and Dilution at AngloGold Ashanti, Iduapriem Mine using Blast Movement Monitoring System
Blast Movement Monitoring (BMM) system is a new method of determining material movement during blasting in order to minimise ore loss, dilution and sometimes misclassification. The BMM system was introduced at AngloGold Ashanti Iduapriem (AAIL) Mine in the first quarter of 2013 as a result of reconciliation challenges at the start of operation at the Ajopa Pit in the first quarter of 2012. Since the introduction, there has been improvement in reconciliation, but the cost implication became worth assessing because of dwindling gold price. The main objective of this paper, therefore, is to assess the benefits or otherwise of BMM system on blast induced movement at Iduapriem Mine. The study comprises data collection on BMM system at AAIL and its analysis, as well as cost and benefit analysis. From the BMM data analysis, it was observed that, the bottom flitch of the blasted material moved more than the top flitch in the horizontal direction while the reverse was the case for the vertical movement. The cost-benefit analysis from four shots analysed revealed that there was a benefit of $753 835 which translates into 650% return on investment. Thus, the use of the BMM system has positive financial impact on Iduapriem Mine. Continuous use of the system as a grade control practice has, therefore, been recommended for the Mine, especially with shots containing ore. Furthermore, a dedicated team for this task has been recommended to enhance efficiency. Finally, high precision GPS has been suggested to be added to the detector instrument to make surveying of pre-blast and post-blast BMM points easier and faster. Keywords : Blast Movement Monitoring System, Ore Loss, Dilution, Misclassification, Reconciliation
