[Energy requirements of miners engaged in open-pit coal mining].

It has been found that according to the value of daily energy consumption the coal miners engaged in open-cast mining should be referred to group III-IV of work intensity. The determining component of daily energy consumption is energy consumption during the working period the value of which depends on the character of working activity and duration of the working shift. The method of strict evaluation of the calorific value of the food taken and the control of body mass is acceptable for the assessment of daily energy consumption.
