The construction of underground work depends on many factors. The most important factors are the geological, hydrological, and topographical conditions of the construction site. The application of design and construction measures must be grounded on these features of a certain construction area. Thus, it is important to conduct specific studies to determine the most suitable calculation method and construction method for the construction area. This book proposes a reasonable tunnel structure and construction method that can help to correct calculations based on the actual conditions to reduce the construction costs as well as the risk of incidents in the process of constructing and mining.
