The mining of open pit quarries has caused great damage to the local ecological and geological environment, and the problems such as geological disasters brought about by mining have seriously affected the ecological environment of the local and surrounding areas. Carrying out the corresponding ecological restoration project is the main solution at present. With the completion of the ecological restoration project, the evaluation of the ecological restoration level lacks tracking monitoring and data support. This paper proposes the use of remote sensing imagery to assist in the assessment and detection of the subsequent effect of mountain mine treatment. The satellite image data of Chabuga Mountain in 2019 and 2022 are obtained by remote sensing technology, and the post-ecological restoration images in 2022 are obtained with the field inspection, and the NDVI index, WET index, NDBSI index and LST index are used as reference data, and the principal component analysis method is selected to use the remote sensing ecological index RSEI model as the evaluation standard, so as to compare the results of mountain mine restoration project. Research results show that after the mine repair work, the annual average value of remote sensing ecological index of the mines in the study area was 0.56509 in the middle of the ecological restoration project, which was restored to 0.69072, and the remote sensing ecological index was significantly improved, and the ecological restoration work of mountain mine management was effective.
