摘要
针对露天矿开采计划经济评价中运输距离难以准确精细计算导致定量评价结果存在偏差问题,提出一种露天矿开采计划经济评价方法。结合矿山现状,将露天矿开采对象离散化,形成露天矿价值模型。根据运矿道路,计算露天矿价值模型中各价值块的运输距离。获取露天矿开采计划经济评价的各项经济参数,进而构建资源储量开采经济价值评价模型。通过解算该经济评价模型,得到经济评价结果。该方法可满足露天矿开采计划经济评价要求,准确精细地考虑了运输距离对经济价值的影响,提高了露天矿开采计划经济评价结果的科学性和准确性。
In the economic evaluation for open-pit mining plan, it is difficult to accurately calculate transportation distance, leading to deviation of quantitative evaluation results. Aimed at the problem, an economic evaluation method for open-pit mining plan was proposed. Combining with the current situation of the mine, the open-pit mining object was discrete to form an open-pit mine value model. According to the ore transportation road, the transportation distance of each value block in the value model was calculated. Then, each economic parameter of the economic evaluation was obtained, so as to construct an economic evaluation model of resource reserves exploitation. By solving this economic evaluation model, the economic evaluation results were obtained. The method meets the requirements of the economic evaluation of the open-pit mining plan, accurately and finely considers the influence of the transportation distance on the economic value, as well as improves the scientificity and feasibility of the economic evaluation results for the open-pit mining plan.
