Outline
The "double carbon" goal puts forward the dual requirements of low-carbon transformation and ecological protection for the sustainable development of open-pit coal mines. Geological disaster prevention and mining area ecological restoration as its core issues need to adapt to new development needs. In view of the contradiction between energy security and low-carbon development faced by open-pit coal mines under the goal of "double carbon", the research progress of geological disaster prevention and ecological restoration was systematically discussed. In the field of geological disaster prevention, the evolution of traditional disaster characteristics and the emergence of new disasters under low-carbon orientation were analyzed, and the application results of energy-saving monitoring technology, carbon footprint-oriented early warning model and green support technology were sorted out. In terms of ecological restoration, the development status of carbon sink function research, low-carbon ecological restoration technology and carbon sink evaluation method of vegetation-soil system were summarized. On this basis, the existing problems such as technical bottlenecks (conflict between traditional technology and low-carbon goals, difficulty in collaborative carbon sink efficiency and engineering stability, insufficient technology integration, etc.), lack of management mechanism (cross departmental policy barriers, ambiguous rights and responsibilities of stakeholders, lack of regional collaborative, etc.) and insufficient policy support (fragmented policy system, disconnection in standard coordination, imperfect incentive and restraint mechanisms, etc.) were further analyzed. Finally, the three transformation paths of technology (building a low-carbon collaborative technology system), management (establishing a carbon-oriented collaborative mechanism) and policy (improving the low-carbon support and guarantee system) were prospected, which provides a theoretical reference for the collaborative development of "disaster prevention-promoting restoration-carbon sink" in open-pit coal mines.
