Abstract: In order to improve the operability of on-site disposal schemes in coal mines, an automatic generation system of disposal schemes for coal mine accidents based on expert system is constructed. The system integrates emergency plans, safety rules and regulations, rescue and disposal methods and experiences from experts and accident cases. The generated disposal schemes can be reasoned according to the real-time information of the accident scene. Besides, commanders can input inquiry information to search historical accident cases which meet the inquiry conditions and are most similar to the current accident characteristics for obtaining practical experience knowledge support.
