INTELLIGENT COAL MINE UNDERGROUND CARBON EMISSION COMPREHENSIVE EVALUATION AND FREQUENCY CONVERSION CARBON REDUCTION METHOD

The invention discloses an intelligent coal mine underground carbon emission comprehensive evaluation and variable-frequency carbon reduction method which comprises the following steps: acquiring the total ventilation amount, the total gas extraction amount, the total power supply amount, the total drainage amount and the total transportation fuel oil amount of a coal mine mining area, and summarizing and transmitting the acquired data to a carbon reduction evaluation platform; the carbon emission evaluation system calculates ventilation carbon emission, gas extraction carbon emission, power supply carbon emission, drainage carbon emission, transportation carbon emission and the total amount of carbon emission according to the stages before mining, during mining and after mining and the obtained data; the calculation result is compared with the corresponding indexes of the carbon emission and the total carbon emission in the corresponding stage, and whether the indexes exceed the standard or not is judged; according to the intelligent coal mine underground carbon emission comprehensive evaluation and variable-frequency carbon reduction method, the whole-process carbon emission evaluation of coal mining areas at different stages is realized, the pertinence of an evaluation system is improved, and each carbon emission can be adjusted through feedback of a comparison result so as to meet the effect of centralized utilization of energy.
