CHINA MINE ENGINEERING

This paper takes the construction of large diameter deep shaft in an iron mine as the engineering background, through careful analysis of construction organization design, carry out research on Optimization of process, many factors such as construction period、safety、economy and on-site construction are comprehensively considered，through scientific planning and reasonable adjustment of process, the waiting time of night construction is reduced, the continuity of construction is ensured, and the efficiency of shaft construction is improved.
