Abstract: 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.
