在露天矿的设计中,考虑雨季的影响,有的是降低露天矿工作天数,减少设备作业天数,有的是降低设备作业效率……对设计所采取的各种参数和有关数据,到底有多大根据?原设计所计入的各项影响参数是否符合矿山的生产实际?目前国内尚无很完善的资料分析。为了总结经验,笔者结合井冲角露天矿的生产实践,以该矿十一年逐月的采剥量和降雨量的统计、观测值及有关设备配套实际能力的统计资料,采用数理统计的方法作一分析研究。
In the design of opencast mines, taking into account the influence of the rainy season, some are to reduce the number of days of open-pit mines, reduce the number of days of equipment operations, and in some cases, to reduce the operation efficiency of equipment. In the end, how are the various parameters and related data taken for the design? All the parameters involved in the impact of the mine’s production is in line with the actual production? At present there is no very comprehensive domestic data analysis. In order to summarize the experience, the author combined with the production practice of open pit mine in Jingchuang Angle Mine, take the statistics of the number of mining and stripping and rainfall of the mine on a monthly basis for eleven years, the observation value and the statistical data about the practical ability of related equipment, Make an analysis.
