劳动生产率可以用许多不同的方法来确定,而基本方法是计算员工的每工班、每工时的产量,也可以按单位投资所获采出矿石的吨数计算。这里仅限于探讨按每工时采出矿石吨数计算的劳动生产率。有时,劳动生产率仅考虑直接从事凿岩爆破、装载和运输等采矿作业的采矿工作面人数。另一种则包括全部地下开采所消耗的工时数,包括了设备维修保养人员。还有一种把地表作业的工时数,如计划员和矿井提 Labor productivity can be determined in many different ways. The basic method is to calculate the number of workers per job, per labor hour, or the tonnage of ore that is mined per unit investment. This is limited to the discussion of labor productivity calculated on the basis of tons of ore produced per working hour. At times, labor productivity accounts only for the number of mining facets directly engaged in mining operations such as rock drilling, loading and transportation. The other includes the total number of man-hours spent on underground mining, including equipment maintenance personnel. There is also a number of working hours on the surface, such as planners and miners
