通过综合分析,分别计算了安家岭露天煤矿经济合理工作线长度、生产规模与技术可行的工作线长度,在此基础上研究了工作线长度、推进度和产量之间的关系,得出了该露天煤矿的目标产能下的工作线长度、推进速度及相关产量,并最终得出该露天煤矿最佳工作线长度。 Through comprehensive analysis, the length of reasonable and reasonable working line, the production scale and the feasible working line length of Anjialing open-pit coal mine are respectively calculated. On the basis of this, the relationship between work line length, propulsion and output is studied. The length of the work line, the speed of propulsion and the related output under the target capacity of the open pit mine, and finally the optimal working line length of the open pit mine.
