矿山立体空间能源化、低碳化利用研究OA

During the long-term large-scale development of China's mineral resources,a vast three-dimensional space both above and under the ground has been formed.Accelerating the energy-oriented and low-carbon utilization of the three-dimensional space of mines is conducive to supporting the green and low-carbon transformation of the mining industry and building a new energy system.This is also crucial for achieving the carbon peaking and carbon neutralization goals as well as ensuring national energy security.This study defines the concept of a three-dimensional space in mines and expounds on the implications of energy-oriented and low-carbon utilization.The current scales and future potentials of various spaces in China's mines are calculated,and the potentials for energy-oriented and low-carbon utilization approaches such as wind and solar power generation,carbon sequestration,and carbon storage are further calculated.Based on the major characteristics of the three-dimensional spaces of mines,the study summarizes five typical utilization modes,namely energy development,energy storage,resource reserve,green expansion and carbon reduction,as well as"science,education,culture,health,and tourism"development.It also analyzes the current utilization status and problems,and proposes a strategic concept with an overall approach and stage objectives.Moreover,the study establishes a strategic framework consisting of"five utilization"paths,including storage and utilization of strategic resources,direct utilization of energy resources,conversion and utilization of power generation and energy storage,carbon reduction-zero carbon-negative carbon utilization,as well as integrated and collaborative utilization.An energy-oriented and low-carbon utilization technology system covering spatial exploration and assessment,restoration and management,energy-oriented utilization,low-carbon utilization,and safety assurance is established.Finally,policy recommendations are proposed,including deepening the preliminary survey of three-dimensional space resources in mines,clarifying spatial ownership,improving the planning system,strengthening support for scientific and technological innovation,and constructing key demonstration projects.
