Wangping derelict mine land was taken as an example, and the catalyst theory was introduced into the study of the renewal of the wasteland. With functional catalyst, landscape catalyst, cultural catalyst and traffic catalyst as its catalyst characteristics, the existing elements in Wangping derelict mine land were subjected to multiple functional replacement, landscape placement, and spatial and functional integration. The material elements such as buildings and components with mining characteristics and non-material elements such as mining culture were retained, inherited, developed, and the transportation system inside the site was integrated and optimized. The construction sequence of the early, medium and long-term development was formulated to inject new vitality into the city and realize the transformation and upgrading of Wangping Coal Mine.
