摘要

本文介绍了影响挖掘机和自卸车性能的因素。给出了铲斗容量为1 ~ 3.5 m3的液压挖掘机(日立、沃尔沃、小松PC、利伯海尔)与铰接式自卸车沃尔沃、贝尔、BelAZ(载重能力为10 ~ 20吨)、采石场自卸车BelAZ、Terex、卡特彼勒、小松(40.100吨)技术准备系数的主要依赖性。为了提高煤矿岩体运输效率，对采石场自卸车的性能变化规律进行了研究。所获得的研究成果使我们在规划煤矿企业短期工作时，可以对采运设备的年运行生产率进行预测评价。

SUBSTANTIA TION OF PARAMETERS OF EXCAVATOR-AUTOMOBILE COMPLEXES AT COAL MINES TAKING INTO ACCOUNT THE RELIABILITY FACTOR

The article presents the factors affecting the performance of excavators and dump trucks. The main dependences of the technical readiness coefficient of hydraulic excavators (Hitachi, Volvo, Komatsu PC, Liebherr) with a bucket capacity of 1...3.5 m3, in combination with articulated dump trucks Volvo, Bell, BelAZ (with a load capacity of 10-20 tons), quarry dump trucks BelAZ, Terex, Caterpillar, Komatsu (40.100 tons) are given. To increase the efficiency of the process of transporting rock mass at coal mines, the regularities of changes in the performance of quarry dump trucks have been studied. The obtained research results allow us to make a forecast assessment of the annual operational productivity of mining and transport equipment when planning the work of coal mining enterprises in the short term.
