  • Abstract

    In this study,the formation background of geological technology for carbon neutrality and its position in the knowledge system of carbon neutrality are outlined.The concept and connotation of geological technology for carbon neutrality are proposed.The important application directions,application models and development prospects of geological technology for carbon neutrality in the process of low carbon coal exploitation and utilization are analyzed and discussed.Current works have shown that the cross-discipline of carbon neutrality science and engineering as a knowledge system of carbon neutrality is emerging.On the basic background of earth science,the interdisciplinary integration of carbon neutrality-related disciplines is becoming the present main research fields and technology development directions of carbon neutrality science and engineering.Geological technology for carbon neutrality is an important component of carbon neutrality science and engineering,and also a key technology to achieve carbon neutrality goal.Carbon dioxide capture,utilization and storage technology,ecological geology and carbon sink technology,emission reduction of coal bed methane and its related resource utilization technology,geological technology for low-carbon development and utilization of fossil energy,high-efficiency exploration and development technology of geothermal resource,geological guarantee technology for efficient and safe development and utilization of new energy,mineralization and carbon sequestration and geoengineering are the current core connotation of geological technology for carbon neutrality.With the development of following technologies,e.g.,CCUS (Carbon Capture,Utilization and Storage) large-scale cluster deployment and whole process technology,coalbed methane continuous efficient extraction and low concentration gas (including ventilation air methane) utilization technology,the whole process technology of exploration,mining and smelting of coal-hosted key metals,ecological geological restoration and reconstruction of mining area and the increase in carbon sink technology,exploration,development and utilization of new energy resources of geothermy in hot dry rock,geological guarantee technologies for the development and utilization of hydropower,nuclear power and other new energy sources with integrated power supply and storage,and solar radiation management frontier technology,some significant progresses have been made for carbon neutrality.The CCUS will be the key to low carbon,clean and efficient utilization of coal technologies such as the low emission coal-fired power generation,coal conversion,coal to hydrogen,coal to special fuels,and coal-based materials.The CCUS in coal base or coal mining area,characterized by coal-based CO2 source,coal-measure CO2 geological carbon sink,CO2 mineralization and fixation and goaf filling and sealing,is an urgent need.In-situ exploration and development of coalbed methane,underground and surface collaborative extraction of coalbed gas,extraction of closed mine gas,utilization of low concentration coalbed methane and ventilation air methane,application model of high-efficiency efficient extraction,utilization and emission reduction comprehensive technology of coalbed methane will be rapidly developed and popularized.The controlling of overburden deformation and the maintaining of surface vegetation ecosystem,the protection of water resources and regional ecosystem,the controlling of mining-induced fractures and greenhouse gas emission and the development and application of green and intelligent mine geological guarantee technology by means of digital mine and energy saving and efficiency improvement contribute to the carbon reduction in coal production process.Ecological restoration and carbon sequestration technology in coal mining areas should be applied to realize the coordination between coal gangue disposal and pollution reduction and carbon reduction,treatment of subsidence area and the increasing of carbon sink,land consolidation and utilization.The application and development of the co-exploration and co-exploitation of coal-type co-associated resources and carbon emission reduction technology should also be accelerated to achieve the breakthroughs of high-efficiency exploration,exploitation and utilization of coal measure gas and coal-type key metals.The geological technology for carbon neutrality mentioned above is of great significance to serve the construction of low-carbon,clean,efficient and safe new energy system and the realization of carbon reduction from sources in China.
