本文研究了电气化铁路运输和汽车运输对露天矿境界内剥岩量的影响,以及剥岩量与露天矿参数有关的主要变化规律。基于对规则的急倾斜矿床开采的分析,本文作者研究了电气化铁路运输和汽车运输对露天矿境界内剥岩量的影响,以及剥岩量与露天矿参数有关的主要变化规律。研究过程中,系采用粘着重量为150吨、载重量为90吨的翻斗车以及载重量为27和40吨的自卸汽车。矿床的开拓沿矿体的底盘进行,采用铁路运输时矿床用折返沟开拓;采用汽车运输时,矿床用回返沟开拓。露天矿底部的最小长度定为1500米。非工作阶段的边坡角为45°。采用铁路运输和汽车运输时的非工作帮坡角分别为26和
This paper studies the influence of electrified railway transportation and motor transport on the amount of stripping rock in the open pit and the main variation rules of the amount of stripping rock and the parameters of the open pit. Based on the analysis of the regular, steep-dip mining, the authors studied the effect of electrified railway transport and motor transport on the amount of peeled rock in the open pit and the main changes in the amount of pealed rock and open pit parameters. In the course of the study, dumpers with an adhesion weight of 150 tons and a carrying capacity of 90 tons and dump trucks with loading capacities of 27 and 40 tons were used. The development of the deposit is carried out along the chassis of the ore body, and the deposit is opened up by the fold-back groove when transported by rail. When transported by car, the deposit is opened up by the return ditch. The minimum length of the bottom of the mine is set at 1,500 meters. The slope angle at the non-working stage is 45 °. The non-working slope angles when using rail transport and motor transport were 26 and
