Abstract：Under the background of global climate change and resource shortage,realizing the goal of"double carbon"has become the common pursuit of all countries,and the exploitation and utilization of mine underground space has become an important way to achieve sustainable development.As an important prerequisite for the exploita-tion and utilization of underground space,fine detection of underground space has attracted extensive attention from the academic community,and is the basis for ensuring the safe and efficient exploitation of underground space.This paper expounds the method principle and current development status of underground space detection technology in mines,systematically combs the underground space detection technology from two dimensions of"air(sky)-ground-well-roadway"and"gravity-magnetic-electric-seismic".Through in-depth analysis and comparison of the differences of ge-ophysical exploration methods in detection range,detection depth,cost effectiveness and anomalous body sensitivity,the applicability of different mining underground space exploration methods to different application scenarios is analyzed,and the advantages and limitations of each exploration method are summarized.The typical ap-plication of underground space exploration in mines is studied.By analyzing the exploration results of practical engi-neering application,the application value of each exploration technology in practical engineering is highlighted,and the practical basis is provided for the future technology optimization.In addition,the development trend of mine under-ground space detection technology in the future is discussed,and the feasibility and necessity of integrated robot re-search on multi-space and multi-dimensional joint detection and underground space perception detection is expounded,which is expected to further improve the accuracy and efficiency of mine underground space detection,and reduce the detection cost and risk of mine underground space detection under complex geological environment.It pro-vides a reference for the future development direction of underground space detection technology in mines.
