Appraisal of some evolving environmental issues relevant to underground space development

Article Abstract:

Underground space policies are imperative to the effective use of underground storage and transportation of wastes and water. Policies have to account for such factors as the geology of potential traverse lines of conveyor belt tunnels for wastes, potential for excessive fractures during excavations, and other zoning and geotechnical hazards to prevent any damage to conveyor lines or the spilling of toxic wastes. A management system that supervises the complex web of conduits is likewise required.
