摘要

本文对蒙古乌姆努戈壁“乌哈库达格”露天矿自卸车运输系统的实际周期时间进行了分析。它检验了最小化运输系统周期时间的可能性,以及影响自卸卡车速度的因素。本研究将露天矿山自卸车道路划分为台阶路、坡道、地表路、自卸车上坡路和自卸车路五段。同时,研究了路段长度、坡度、滚动阻力对循环时间的影响。通过Microsoft Excel程序对数据进行数学回归分析。对于每一个路段,我们比较了三种回归模型的统计计算:线性、二次和指数;因此,本研究共得到30个回归模型。因此,每个路段的周期时间是由最负责任的模型预测。对各路段的载空运动方向进行了测量和计算,结果表明,模型计算的平均值与实际循环时间的差值为0.82秒,相对误差为2.51%。

Cycle Time Analysis of Open Pit Mining Dump Trucks
This study demonstrates a practical cycle time analysis of dump truck haulage system of “Ukhaa Khudag” open-pit coal mine located in Umnugobi Province, Mongolia. It examines the possibility of minimizing the cycle time of the haulage system as well as factors impacting the speed of the dump truck. The current study divides the open pit mine road for the dump trucks into five sections which are bench road, ramp, surface road, dump road uphill, and dump road. Meanwhile, it investigates the influence of the length, the grade, and the rolling resistance of the road section on the cycle time. The data is analyzed using mathematical regression methods via Microsoft Excel program. For each of the five road sections, we compare the statistical calculations of three regression models: linear, quadratic and exponential; thus, a total of thirty regression models are obtained in this research. Accordingly, the cycle time for each road section is predicted by the most accountable model. The loaded and empty direction of the movement is measured and calculated for each road section, and it appears that the difference between the calculated mean value and the actual cycle time of the models is 0.82 seconds with a relative error of 2.51 percent.
