[0002] Historical mines refer to mines that are currently abandoned and will no longer be used for mining activities. Historical mines have major ecological problems such as geological environment problems, land damage and vegetation destruction. Therefore, ecological restoration of historical mines is necessary. According to the on-site damage situation, the main ecological restoration methods include natural recovery, assisted regeneration, ecological reconstruction and transformation utilization.

[0003] During the ecological reconstruction process, it is necessary to take soil from other places and plant vegetation on the soil. Since the mine slope needs to be rebuilt over a large area and the mine slope also has a certain slope, it is not convenient to transport the soil to the corresponding area on the mine slope. In addition, the vegetation also needs to be watered and fertilized after planting. The use of traditional artificial fertilization makes the mine ecological vegetation restoration work heavy and the restoration efficiency low.
