冻土是指温度低于或等于0℃且含有冰的土体或岩体，它对温度特别敏感，其物理力学性质会随温度的变化而产生显著变化。木里矿区位于祁连山南麓，长期无序开采造成地形破坏、冻土退化、水源涵养能力下降，成为全国生态环境问题突出区域。为了研究矸石山、矿坑对多年冻土的影响，布设了5个多年冻土地温孔，获取冻土地温的主要方法是埋设测温电缆，通过CR3000的数据采集功能获得测温电缆不同时间的阻值变化，利用标定系数和电阻值的对应关系计算出温度值。依据冻土对温度的敏感特征，地温的变化情况，能够结合其他要素分析出人类开采对冻土的稳定性的影响机理及程度以及生态修复对矸石山内多年冻土影响，从而来指导后期人类活动中的冻土保护措施及生态修复等相关工作。

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.
