Strategies for Increasing Sinks and Reducing Emissions in Mines Planting Rehabilitation: A Case Study of Dongming Mine in Hulunbuir

The burning and exploitation of coal and other fossil energy emits a large amount of greenhouse gases, resulting in serious ecological problems. As an effective method to increase carbon sequestration, planting rehabilitation helps to improve the carbon sequestration capacity of mines. In order to explore the carbon sequestration potential of planting rehabilitation, this paper took Dongming Mine as the research object to calculate the carbon reserves of local plants, soil and water. The results showed that the total carbon sequestration of plants, soil and water was 5072 t, the annual carbon emission of the mine was about 24,988 t, and the total carbon sequestration could offset about 20% of the carbon emission. Based on the above data, the mine was divided into six areas according to the development plan, and the corresponding ecological restoration measures were put forward for different areas to enhance the local carbon sequestration and realize the increase of sinks and emission reduction of the mine.
