5 statistical coverage and calculation methods

5.1 statistical range Comprehensive energy consumption of iron ore underground mining, including mining process is mainly the production system (mining, underground crushing, transport, promotion, compressed air, ventilation, supply and discharge Water, lighting, production scheduling command system), auxiliary production system [machine repair, auto repair, electrical repair, explosives plant (library), testing, testing, measurement, environmental protection, animal Power supply] and the physical volume of mining production and services directly affiliated production system (office, dining room, bathroom) consumed by a variety of energy and Converted into standard coal in accordance with the provisions of GB/T 2589's. Coal power off when using the coefficient value 0.1229kgce/(kW · h). 5.2 statistical requirements In the statistical community area, untapped energy output is not as energy output statistics. 5.3 Calculation Method 5.3.1 Underground Mining iron ore unit of product comprehensive energy consumption calculation Comprehensive energy consumption per unit of iron ore underground mining by the formula (1). edc = Esj (1) Where. Edc --- comprehensive energy consumption per unit of iron ore underground mining, in kilograms per tonne of coal equivalent (kgce/t); Total amount of all kinds of energy, turning coal iron ore --- Esj statistics actually consumed during underground mining, in kilograms of standard coal (kgce); The amount of iron ore during the period P --- Statistics underground mining output, tonnes (t). 5.3.2 iron ore underground mining unit of product than the comprehensive energy consumption calculation Iron ore underground mining unit of product than the comprehensive energy consumption according to formula (2). ekb = edc (2) Where. ekb --- underground mining unit comprehensive energy consumption of comparable products, in kilograms per tonne of coal equivalent (kgce/t); K --- underground mining iron ore consumption adjustment factor. 5.3.3 adjustment coefficient calculation iron ore underground mining To achieve comprehensive energy consumption per unit of product than iron ore underground mining, considering the main factors affecting energy consumption, the use of actual adjustment coefficient Energy consumption. Iron ore underground mining adjustment coefficient according to formula (3) Calculated. K = (1 K1 K2 K3 K4 K5) × K6 (3) Where. K1 --- lift coefficient, see Table A.1; K2 --- drainage coefficient, see Table A.2; K3 --- mining methods and, where filling method, K3 = 0.05, empty field method, K3 = 0.03; K4 --- ventilation coefficient, see Table A.3; K5 --- heating coefficient, see Table A.4; K6 --- plateau coefficients in Table A.5. 5.3.4 Multi underground mining iron ore mining area per unit of product than the comprehensive energy consumption calculation More underground mining iron ore mining area comprehensive energy consumption per unit of product should be comparable formula (4) Calculated. ekb = i = 1 ei, kb × Pi () i = 1 Pi (4) Where. ei, kb --- i-th District of the comprehensive energy consumption per unit of product than, in kilograms per tonne of coal equivalent (kgce/t); Ore production Pi --- i-th mining area, tonnes (t); n --- the number of mining area.
