Abstract: The choice of mineral deposit development program is of importance to the underground exploitation. Huangmailing phosphates mine will be transferred from open-pit to underground mining. In view of ensuring the security during the transition period from open-pit to underground mining,four shaft development viable programs were proposed. DEA model was established by using data envelopment analysis from such main evaluation indexes as capital investment,operating costs,project volume,open-pit mining impact,environmental protection,construction difficulties,ventilation condition and so on.  Through using DEA model to analyze these shaft developments,Wangjiashan shaft development program was firstly recommended. The results show that the data envelopment analysis method is an effective optimization program with a broad application prospect.
