一般用三种方法在本部门水平上预测露天铁矿企业的采矿劳动生产率,这三种方法是:定额法、趋势外推法和经济数学模拟法。劳动生产率定额预测法是以设备需要量的计算为基础,而设备需要量是由露天开采专家根据预计开采量计算的。经济数学模拟法是最重要的一种预测方法,能最全面反映部门的发展规律。模拟的任务首先是建立完全反映预测过程的模型。 Three methods are generally used to predict the mining labor productivity of the open-pit iron ore enterprises at the department level: the quota method, the trend extrapolation method and the economic mathematical simulation method. Labor productivity quota forecasting method is based on the calculation of equipment requirements, and equipment requirements are calculated by the open-pit mining experts according to the predicted production. Economic mathematical simulation method is the most important method of prediction, which can most fully reflect the law of the department’s development. The simulation task first and foremost establishes a model that fully reflects the forecast process.
