Abstract：The Yushan Skating Rink Project was situated at the bottom of Yushan Hill in a city s central busy region- It was a large-span shallow underground cavern- The surrounding environment of this project was complex with specialities of high technical requirements and big constructing difficulties. Therefore，during the construction procedure by drilling and blasting method，the control blasting technique must be employed， not only for decreasing the influence of blasting vibration on the surrounding buildings， but also for controlling the distance of flying rocks and for lowering the blasting noise. The applications of the control blasting technique in the Yushan Skating Rink Project are expounded in detail in this paper.
