[Integration of Mine Ecological Restoration Technology：Connotation，Logic，Path，and Practice]

Technology integration has become a key path for multi-disciplinary，multi-field，and multi-technology cooperation in mine ecological restoration. It is the inevitable choice to solve the comprehensive mine ecological environment problem. Through data analysis and field investigation，the scientific connotation，theoretical logic，classification characteristics，and practical dimension of the integration of mine ecological restoration technology were thoroughly sorted out and studied. The research shows that at the level of theoretical framework，it is necessary to comprehensively grasp the logic of four aspects：demand，timing，space，and hierarchy. Due to the difference of resource type，geographical environment，mining mode，mine state，restoration target，etc.，the content，direction，path，and goal of the integration of mine ecological restoration technology also showed different characteristics. The technology integration practice of mine ecological restoration in China can be summarized into five dimensions：single technology，important links，key regions，whole element of mine system，and the whole life cycle of mining. The research indicates that the technical integration of mine ecological restoration is a three-dimensional and multi-dimensional working process，having high requirements for science，rationality，and operability，and needs to comprehensively consider various factors such as mineral species，environment，and mining mode，so as to carry out technical integration and application due to mine conditions. In practice，the space for single technology integration innovation is still large，and the technology integration of important links and key regions can be further expanded and applied in combination with demand. The technology integration of the whole element of mine system and the whole life cycle of mining will be an important topic in the future research and development of mine ecological restoration.
