Abstract: In order to achieve the purpose of improving the quality and efficiency of ecological resto⁃ ration and long-term maintenance of the results of abandoned mines left over from history，in view of the practical difficulties of such mine restoration，such as heavy governance，light utilization and low degree of resource utilization，a trinity restoration model of“ecological restoration-resource utilization-industrial collaboration”is constructed by taking an abandoned mine as an example.First of all，through the slope re⁃ pair and reinforcement，soil backfill，vegetation restoration and other engineering technologies to eliminate the hidden dangers of land disasters，the three-dimensional vegetation space of“tree-shrub-vine-grass” is constructed to improve the stability of the ecosystem.Secondly，combined with the needs of regional peo⁃ ple′s livelihood and the conditions of the mining area，the functional utilization of the restored land is car⁃ ried out，and the suitable area is planned as a public welfare cemetery to realize the intensive revitalization of the land and form a“ecology-people′s livelihood”synergy mechanism. The operation income of the cem⁃ etery feeds back the ecological maintenance to ensure the long-term maintenance of the restoration results. The practice results show that the collaborative restoration model can effectively achieve multiple goals such as ecological improvement，people′s livelihood security and land resource activation，and provide a reference path for the systematic management of similar abandoned mines.
