In view of the current situation that mine main ventilator can only monitor parameters, can not identify types and causes of the fault, the expert decision support system for safety hidden danger of main ventilation was researched and developed. On the basis of investigating safe operation condition, as well as analyzing and collecting fault cases of main ventilator in major domestic coal mines, the main types of safe hazards and the warning judgment criteria were determined. Then the methods of safety evaluation and treatment strategies were analyzed, and function model and information database system of expert knowledge representation which based on production rules were established. The overall framework of the decision support system and the software interface were designed and developed. This operational software has been installed and applied in Nanliang coal mine currently, the preliminary operating results are favorable and have achieved the desired objectives.
