People's Governments of all provinces, autonomous regions, and municipalities directly under the Central Government:

　　In order to strengthen urban geological safety risk prevention and control, effectively prevent and resolutely curb the occurrence of major and serious geological safety accidents, forcefully safeguard the lives and property of the people, and improve the level of urban modernization governance, with the consent of the State Council, the following matters are hereby notified.

　　 I. Attach great importance to urban geological safety risks. All regions and relevant departments should adhere to the guidance of Xi Jinping Thought on Socialism with Chinese Characteristics for a New Era, fully implement the spirit of the 20th National Congress of the CPC, comprehensively, accurately, and completely implement the new development philosophy, effectively enhance political standing, take the overall national security outlook as the guide, adhere to the people-centered approach, coordinate development and security, attach great importance to geological safety risks in urban engineering construction and resource development, adhere to the principles of safety first, addressing both symptoms and root causes, systematic control, and coordinated strategies, strengthen risk prevention and control systems and capabilities, make every effort to improve urban safety levels, effectively prevent and resolutely curb the occurrence of major and serious accidents, and create a livable environment for the people where they can live and work in peace and enjoy happiness and health.

　　 II. Strengthen urban geological basic investigation work. Focusing on cities at the prefecture level and above, accelerate the promotion of urban geological basic investigation work within the urban development boundaries. Local people's governments should organize relevant departments to conduct urban geological surveys, fully utilize remote sensing, geophysics, Internet of Things sensing, and ground-based digital survey technologies, focusing on urban geological safety, underground space resources, and environmental geological issues, focusing on the needs of urban construction and deep resource development, systematically organize existing geological data from natural resources, housing and urban-rural construction, water administration, and emergency management departments, conduct standardized and digital processing, and establish an urban geological big data sharing platform. Karst collapse, goaf collapse, and loess collapse geological safety problems As the focus, conduct thematic surveys with an accuracy of not less than 1:10000, identifying relevant geological conditions and the distribution of hidden dangers within the depth range affected by urban engineering construction. Based on the thematic surveys, conduct hazard assessments and risk zoning, divide risk levels, and form a "one-map" of urban geological safety risks.

　　 III. Strengthen the control of national land spatial planning. Give play to the leading role of geological survey work in national land spatial planning. In the process of compiling and revising urban national land spatial plans, fully utilize the results of geological hazard risk surveys to conduct risk assessments. According to the assessment results, delineate geological hazard risk zones and reasonably arrange various construction land uses; newly added construction land layouts should avoid areas with extremely high and high geological hazard risks. If it is indeed impossible to avoid them, measures should be taken to eliminate or prevent geological hazard risks; urban built-up areas should do a good job in spatial arrangement for disaster prevention and mitigation, reducing the impact of geological hazards on the ground. When conducting regional assessments in various development zones, industrial parks, new areas, and other areas with conditions, geological hazard risk assessments should be strengthened, and when supplying land, the assessment results should be provided to land-using units, urging them to take necessary disaster prevention and mitigation measures to reduce safety risks from the source.

　　 IV. Strictly implement relevant laws and regulations on geological safety in urban engineering construction. According to the relevant laws and regulations, the housing and urban-rural construction departments at all levels and other relevant departments should strengthen supervision and management of the quality of construction projects. Relevant units should strictly abide by the provisions of relevant laws, regulations, and mandatory standards for engineering construction, and pay attention to regional experience, focusing on the characteristics of the project, and carry out urban engineering geological exploration, design, construction, and supervision work. The construction unit will take the lead in organizing and implementing management work to ensure the necessary conditions and investment; the exploration unit should submit exploration reports that are true, accurate, and meet the requirements, analyze and clarify the geotechnical risks that may be caused by geological conditions, and propose corresponding technical preventive measures. If necessary, propose special exploration suggestions. The design unit should propose targeted design measures based on the exploration report and adjust and optimize the design based on the dynamic opinions provided by the construction unit. The construction unit should strictly organize construction in accordance with the engineering design drawings and construction technical standards, strengthen geological risk identification and dynamic tracking, and take targeted measures in a timely manner if any discrepancies are found between the actual geological conditions and the design.

　　 V. Strengthen the control of geological safety risks in the exploration and development of urban geothermal and groundwater resources. Relevant departments at all levels should combine the characteristics of geothermal and groundwater resources in their respective regions and geological conditions to strengthen supervision and management of the exploration and development activities of urban geothermal and groundwater resources and promptly make preventive requirements for potential geological safety risks. When conducting geothermal and groundwater resource exploration in urban built-up areas and densely populated areas outside urban built-up areas, the responsible unit (including exploration and construction units, mine right holders, etc.) should systematically collect geological risk element data such as soil and rock properties, groundwater, karst, loess collapse, goafs, shallow gas, and the distribution of underground facilities in the working area, fully conduct geophysical exploration of the deep strata involved in the exploration activities, and identify potential hazards such as ground collapse, ground subsidence, and sudden water and soil gushing that may affect urban safety; exploration and design must be prepared in accordance with relevant technical regulations, expert review of construction safety, and strengthen the quality and safety management of the construction process, and take targeted preventive measures for geological safety hazards according to geological conditions to avoid ground collapse, ground subsidence, and sudden water and soil gushing disasters.

　　 VI. Strengthen the daily monitoring and control of urban geological safety risks. Local people's governments organize relevant departments to establish and improve a collaborative mechanism for geological safety risk assessment, decision-making evaluation, and risk control, and refine and implement the management responsibilities of all parties. Conduct a ground survey of urban underground public spaces, comprehensively monitor data, detection data, historical collapse data, etc., and establish a monitoring and early warning control platform covering multi-source data in accordance with the requirements of urban safety risk comprehensive monitoring and early warning regulations, realize dynamic update, joint construction and sharing, real-time monitoring of data information, and strengthen the connection with related platforms and systems, establish a multi-faceted and multi-parameter monitoring system, scientifically guide ground collapse early warning and the treatment of road underground diseases, especially the treatment of underground pipeline damage and leakage, and improve early warning capabilities. Strengthen dynamic monitoring of groundwater and geothermal resource development and integrate monitoring results into early warning monitoring control platforms. Improve the emergency rescue coordination mechanism for sudden geological safety events and organize related emergency rescue work.

　　 VII. Improve relevant standards for urban engineering geological exploration, geological hazard prevention and control, and resource exploration and development. Strengthen the implementation of current standards such as the code for urban planning and engineering geological exploration, the code for geological exploration of industrial and civil engineering construction, the code for urban geological surveys, the code for geological hazard risk assessment, the code for ground subsidence measurement, and the code for supervision of geological hazard prevention and control engineering, and promote the application of new technologies and methods to improve the effectiveness of urban geological safety risk prevention and control work. Seize the opportunity to revise and improve the content and clauses in the current standards for geothermal resource geological exploration, shallow geothermal energy exploration and evaluation, and geothermal drilling technology procedures that cannot meet the needs of urban geological safety risk prevention and control. Accelerate the promotion of the preparation and revision of relevant standards such as the code for karst collapse investigation, the code for geothermal recharge technology, and the code for dynamic monitoring of geothermal resources, strengthen the implementation of green exploration requirements, and fully consider the impact of engineering construction and resource exploration and development on the geological environment and safety risks of the city.

　　People's governments at the provincial level should earnestly strengthen organizational leadership, consolidate the main responsibility of urban people's governments, formulate detailed implementation plans, earnestly implement various measures and tasks, and ensure that all deployments and requirements for strengthening urban geological safety risk prevention and control work are implemented.
