Abstract

The invention provides a method and a structure for sealing and storing carbon dioxide by using a strip mine pit and a mining method. The method for sealing and storing carbon dioxide by using the strip mine pit comprises the steps: a step of treating the bottom of the mine pit; a slope treatment step; a material manufacturing step; a first layer construction step; a current layer construction step; and a carbon dioxide injection step, wherein according to the sealing and storage requirements, the slope treatment step, the material manufacturing step, the current layer construction step or the carbon dioxide injection step are executed one or more times. According to the invention, co-processing of various industrial solid wastes can be realized, reduction, resource utilization and safe processing of the wastes are realized, carbon dioxide is synchronously added for sealing and storage, the utilization value of the mine pit is greatly improved, secondary benefits are generated, a carbon sequestration engineering technology is realized, and a solution is provided for early carbon neutralization.

Description

technical field [0001] Embodiments of the present invention generally relate to the technical field of greenhouse gas disposal, and more specifically, relate to methods, structures and mining methods for sequestering carbon dioxide in open pits. Background technique [0002] At present, global environmental issues have become the focus of attention of the international community, which has put forward a major strategic demand for environmental technology innovation. On September 22, 2020, the Chinese government proposed at the 75th session of the United Nations General Assembly: "China will increase its nationally determined contribution and adopt more powerful policies and measures. achieve carbon neutrality by the end of the year." To achieve carbon peaking and carbon neutrality, in addition to improving the emission reduction efficiency of industrial processes, it is also necessary to realize the capture and storage of carbon dioxide. Research teams at home and abroad h...
