Abstract: In order to ensure the safety of personnel life and property and the safety of ecological envi⁃ ronment in the process of in-situ leaching mining of ionic rare earth ore，the influencing factors，instability warning and prevention and control measures are systematically sorted out for the slope stability problem un⁃ der the action of in-situ leaching.By analyzing the influence mechanism of factors such as topography，strati⁃ graphic lithology，leaching solution and rainfall，the application status of prevention and control measures such as monitoring and early warning，injection parameter optimization，engineering treatment and ecologi⁃ cal protection is summarized.The research shows that there are still some deficiencies in the current research on the coupling mechanism of multi-field (seepage field，stress-strain field，chemical field)，the applicabil⁃ ity of liquid injection parameters and green prevention and control technology under the condition of in-situ leaching.In the future，it is necessary to strengthen the research on slope stability under multi-factor cou⁃ pling，promote the application of new reinforcement technology，and improve the classification standard of liquid injection parameters.This study can provide a comprehensive and in-depth reference for the study of slope stability of ionic rare earth mines and promote the development of safe and efficient mining technology.
