Underground Space Development Key Planning Factors

Historically underground space has been developed on a first-come-first-served basis around the globe. Reviewing these global experiences, key factors to improve underground development practices are discussed. Issues such as effective identification of colocation opportunities, successful integration of underground with surface developments and requirements for data availability are highlighted and their impact on underground space planning is clarified. Where these are clearly understood and incorporated into the process, underground space planning can be improved and carried out efficiently in a sustainable manner.
