Abstract: In order to have a science judgment on the mine ventilation status of the coal production mine, a comparison on the reconstruction alternatives of the mi ne ventilation system in the old mines was conducted.Based on the summarization on the study achievements related to the domestic mine ventilation and in compariso n with the present status of the mine ventilation, the factors affected to the safety and reliable operated ventilation systems in the old mines were analyzed and the safe ty evaluation index system actually to mine ventilation system was established.The index system would be including the 13 clear defined and practical indexes of the te chnical feasibility, economic rationality and safety reliability.The practical verification showed that the evaluation index system would have the references to the safety management of the mine ventilation system in the old mining area.
