露天矿用卡车燃油消耗的动态统计分析与评价

Dynamic statistical analysis and evaluation of mining truck fuel consumption

在露天煤矿卡车运输成本管理中,燃油消耗指标的统计分析是日常管理十分关注的重要的经济指标。但是这一指标在露天矿企业的统计计算中有多种表达形式。从卡车运用工程角度分析,卡车运输过程是发动机发出功率产生燃油消耗的过程,也就是卡车通过消耗燃油输出了运输功t.km。超大型露天矿的矿用卡车的运力相当大,结合通用运输指标,笔者提出了矿用卡车的燃油消耗指标为kg(/100 t.km),并利用这样的指标数据统计整理了某超大型露天煤矿在2011年1月到6月的多型矿用卡车发生的数据样本,利用这批样本,做了正态分布的曲线拟合、卡方验证。运用统计性描述对这几型卡车的近期油耗指标的影响因素做了分析、评价。

Truck transportation costs in coal mine management, statistical analysis of fuel consumption indicator is very concerned in the daily management. But the statistical indicators in the calculation of open-pit mine enterprises have a variety of forms of expression in. From the truck by engineering perspective, the transportation process is the truck engine power produce fuel consumption process, is also the truck through the transportation fuel consumption output power t＇km. Super large open pit mining trucks carrying capacity is quite large, combined with general transportation index, the author puts forward the mining trucks of fuel consumption indicators for kg/（100 to kin）, And to use this data statistics completed a super large open coal mine in 2011 January to June mining trucks that data samples. Use this batch of sample, do the normal distribution curve fitting, chi-square test and verify. Using statistical description of this type of a few truck fuel consumption indicators of recent influence factors analysis, evaluation.
