Following our Institute's involvement in the physiology of mining work (since 1953), this paper deals with underground work load investigated in terms of time, energy expenditure and heart rate in coal miners working with various types and degrees of mechanization. Results showed that a chamber coal face and at heading (coal or sterile rock) mechanization of haulage and loading (conveyor belt and loading machine) led to 50 -- 100 kcal reduction of energy expenditure/hour. At longwall faces, mechanization of haulage (by conveyor) or hewing and loading (with drum-combine) shortened shoveling time, while there was an increase of manual work in the tasks of supporting which was conducive to metabolic rates of 300 kcal/hour. In the case of fully mechanized coal working, including supporting, there was a significant decrease of energy expenditure.
自1953年以来，我院一直参与采矿工作生理学研究。本文探讨了不同机械化类型和程度的煤矿工人在地下工作的负荷，涉及时间、能量消耗和心率等方面。结果表明，在房柱式采煤工作面以及巷道（煤巷或岩巷）中，运输和装载（输送带和装载机）的机械化使每小时能量消耗减少50 - 100千卡。在长壁工作面，运输（通过输送带）或采煤与装载（使用滚筒联合采煤机）的机械化缩短了铲煤时间，而支护工作中的体力劳动增加，这有助于使代谢率达到每小时300千卡。在包括支护在内的综采情况下，能量消耗显著降低。
