摘要
通过统计分析2010年和2011年露天矿山的日矿石产量和计算品位数据,对数据的特征值和置信度进行分析和假设检验,并通过故障率函数分析2010年和2011年的变化,得出目前生产工艺中存在的问题及工艺的可靠度变化,提出具有操作性的建议。
By analysis of daily ore yield and calculated grade data of a open-pit mine in the 2010 and 2011 year, characteristic values and confidence degree of data were analyzed and hypothesis tested, changes between 2011 and 2010 year were analyzed through failure rate function, existing problems in current production process and reliability changes of process were obtained, and operational recommendations were proposed.
