Abstract: In view of its optimization potentiality in mining sequence, development project, mining methods, ventilation system, intermediate section transport level and transportation system, production subsidiary facilities and service facilities in original implementation plan of joint construction of Lilou-Wuji iron mine. The whole production system become perfect and more reasonable through analysis, research and optimization from above aspects based on the original implementation plan. By this way, the infrastructure construction is obviously shortened, meanwhile construction schedule speeded up, construction period shortened, and the investments and manufacturing costs reduced. The adequate production and service facilities provide a guarantee for the smooth production and business development.

Key words: Joint construction, Implementation plan, Development project, Optimization
