Abstract: To clarify the relationship between mining development and regional construction, this study constructs an integrated research path for mining heritage. Taking A-gan Town, in Qilihe District, Lanzhou City, Gansu Province as a case study, the paper introduces industrial archaeology theory to analyze the intrinsic connection between its mining development and the spatial characteristics of mining heritage, as well as the heritage features. The research shows that the evolution of A-gan Town's urban space is highly correlated with the mining development cycle, conforming to the general characteristics of mining towns that are 'built around mines and decline with the exhaustion of mines'. Due to the influence of terrain, resources, transportation, and other factors around the mining areas, four types of production-residential patterns have emerged: 'mixed' 'surrounding' 'series' and 'separate', which have influenced the formation and development of urban settlements. The layout of mining areas is influenced by both terrain and mining production processes, often adopting a strip layout form. Meanwhile, the mining architectural landscape heritage within the town is centered around the mining areas, showing a distribution pattern of 'widely dispersed, locally concentrated', further highlighting the intrinsic connection between A-gan Town's urban space and the mining area layout. Given this relationship, the preservation strategy should not be limited to the protection of some typical heritage, but should adopt a more comprehensive and systematic approach. Therefore, an integrated preservation strategy of 'landscape ecological restoration-spatial integration-holistic protection-regional collaboration' is proposed, aiming to achieve comprehensive protection and sustainable development of A-gan Town's mining heritage.
