%X Frozen soil refers to soil or rock mass with a temperature lower than or equal to 0 ℃ and containing ice. It is particularly sensitive to temperature and its physical and mechanical properties will undergo significant changes with temperature. The Muli mining area is located at the southern foot of the Qilian Mountains. Long term disorderly mining has caused terrain damage, permafrost degradation, and decreased water conservation capacity, making it a prominent area of ecological and environmental problems in China. In order to study the impact of gangue hills and mines on permafrost, five permafrost soil temperature holes were set up. The main method of obtaining permafrost temperature is to bury temperature measurement cables, and obtain the resistance changes of temperature measurement cables at different times through the data acquisition function of CR3000. The temperature value is calculated using the corresponding relationship between calibration coefficients and resistance values. Based on the sensitive characteristics of frozen soil to temperature and the changes in ground temperature, combined with other factors, the impact mechanism and degree of human mining on the stability of frozen soil, as well as the impact of ecological restoration on permafrost in gangue mountains for many years, can be analyzed to guide later human activities such as frozen soil protection measures and ecological restoration.
