摘要
近几年来,诸多学者对煤矿生产成本预测模型进行了研究,但目前还尚无针对露天煤矿生产成本的预测模型。分析了露天煤矿生产成本构成及主要影响因素,以所建立的露天煤矿生产成本数据库为基础,根据露天煤矿生产成本不同科目的类型,分别建立了费用计算模型、费用计提模型及类比预测模型,对露天煤矿生产成本进行了预测,并进行了案例验证,验证结果表明该模型预测的生产成本是较为准确和可信的,从而为相关露天煤矿生产企业科学管控煤炭生产成本提供了参考和依据。
In recent years,many scholars have studied the prediction model of coal mine production cost,but there is no prediction model for the production cost of open pit coal mine.The production cost composition and main influencing factors of open pit coal mines were analyzed,based on the established production cost database of open pit coal mines,according to the types of different production costs of open pit coal mines,a fee calculation model,a fee accrual model and an analog prediction model were established respectively,and the production cost of open pit coal mines was predicted and case verification was carried out.The verification results show that the production cost predicted by the model is more accurate and credible,which provides a reference and basis for the relevant open-pit coal mine production enterprises to scientifically control the coal production cost.
