Abstract: Different forms of development haulage in mines were investigated considering the production situation of Hongda Iron Mine，and four key issues in optimal design of development haulage were solved.Proper development haulage was firstly selected by comparison with truck and semi-continuous haulage.Secondly，reasonable crushing station was chosen by comparing four kinds of stations which are full movable，movable，semi-fixed and fixed respectively.Subsequently threshold point between truck and semi-continuous haulage was decided by using graphic method and through regression analysis of haulage costs.The moving step distance of crushing station was found by obtaining the optimal solution with quantitative solution and linear model.At last，a set of cost-effective semi-continuous haulage system composed of truck，movable crushing and belt conveyor was recommended to save haulage cost.It plays a significant role in increasing economic efficiency for the mine.

Key words: Development haulage, Movable crushing, Semi-fixed crushing, Semi-continuous Hauling, Belt conveyor
