In order to solve the problem of comprehensive utilization of bulk solid waste and ecological restoration of abandoned mines in Inner Mongolia Autonomous Region, selfStarting in 2022, led by the Academy of Eco-Environmental Sciences of the Autonomous Region, the scientific research team of national and domestic universities and other scientific research teams will focus on "Key technologies and applications of bulk solid waste pollution reduction and carbon reduction in synergistic ecological restoration in mining areas"A series of studies were conducted. Through research, a complete set of soil improvement technology system of solid waste synergistic microbial inoculants has been formed, which not only solves the problem of comprehensive utilization of bulk solid waste and ecological restoration of abandoned mines, but also achieves the effect of pollution reduction and carbon reduction. At the same time, the core technology of this research was successfully applied to 1,415 hectares (21,225 acres) of mining wasteland. The achievement passed 7 placesAcademicians and experts unanimously agreed that the technical level has reached the international advanced level, and some of the technologies have reached the international leading level.recently, the achievement was obtained2023 "First Prize of Green Mine Science and Technology Progress Award" (National Award Office record number 0265).
