Abstract: In order to guide a coal mining area to better realize a low carbonized development,based on an energy integration signification of the coal mining area and a study on a function mechanism of reduced fossil energy consumption,a carbon emission intensity selected as comprehensive evaluation index of low carbon development in the coal mining area could approve relationship between energy integration and the low carbon development in coal mining area from theoretical view. Based on a minin g area as a case,the paper analyzed different energy integration plan affected to the carbon emission intensity and thus the relationship between energy integration and lo W carbon development in coal mining area. An expansion of the energy integration scale would not be a positive correlation to the carbon development degree in the coal m ining area,would be related to the investment size of the plan and to the carbon emission degree and an optimal integration plan could be existed according to the certain C oal mining area.
