Mining process unit energy consumption index

The energy consumption of the mining process refers to the main production system of the mining process (mining, mining, mining, lifting, compressed air, ventilation, water supply and drainage, lighting, etc.), auxiliary production system (mining machine repair, auto repair, electric repair, explosives) Various energy consumed by processing plants, mining tests, testing, metering, environmental protection, power supply, etc., as well as subsidiary production systems that directly serve mining production (pits, canteens, bathrooms, health rooms, restrooms, production dispatching command systems, etc.) Physical quantity (including coal , natural gas , electricity, coke , water, gasoline, diesel, steam, compressed air, etc.). And according to its average low calorific value converted into standard coal calculation. Its calculation formula is:

Unit energy consumption in mining process = fuel consumption + power consumption such as electricity - waste heat recovery external supply

Total amount of mining (raw ore produced) (tonnes) = net consumption of mining process, standard amount of coal (kg)

Total amount of mining (produced ore) (tons of ore) (tons of mine)

Calculation instructions:

The parent item refers to the total amount of mining used in open pit mining, and the unit of calculation is ton of ore; the amount of raw ore mined is used under the pit, and the unit of calculation is tons of ore.
