Problems such as traffic influence and pipeline
relocation are encountered during utility tunnel construction by the opencut
method in old urban areas, whereas mining method is comparatively more
effective. To rationally combine the mining method with the construction
technology of utility tunnels and promote developing utility tunnels in old
urban areas, the history and development of utility tunnels are summarized
using an extensive literature review method. The development history of utility
tunnels is divided into the demanddriven and active
exploration stages. The characteristics of utility tunnels′ development are analyzed. It is recommended that the key to
developing a utility tunnel is to implement its necessary functional
requirements in longdistance projects by the mining
method. According to the technical characteristics of the mining method and
utility tunnels, the development direction is the functional integration of
utility tunnels, comprehensive use of construction shafts, fire prevention,
ventilation, escape, and vertical jacking technology.
