Spatial-temporal evolution of roadway layout system from a space syntax perspective

Human activities and public organizations at different scales are affected by spatial forms and relationships. Using the roadway layout system (RLS) of an underground mine as an example, this paper discusses the potential application of space syntax theories and techniques in the construction and development of the mine underground space (MUS). We quantitatively analysed the spatial-temporal evolution characteristics of the RLS from 2013 to 2020 by combining space syntax theories with multi-scale thinking. The results showed that the core of the degree of integration each year had a strong correlation with the main transport roadway network, the development of the mining edge area being relatively backward. The MUS under consideration was in its development stage from 2013 to 2017, when a basic framework was built outside the mining area and the ore was mined within it. After 2017, the basic framework had been perfected, fully entering the production stage. We used space syntax to analyse and resolve the spatial-temporal evolution of the built MUS, combining the characteristics of the MUS itself, which revealed the development law of the MUS and RLS during the construction process and verified the feasibility of auxiliary decision-making in the process of space planning and construction. The study also showed that space syntax could provide scientific support and useful references for the orderly expansion, rational layout, safe construction, and sustainable development of the MUS.
