Design of multi-person cooperative emergency exercise system in coal mine

Traditional coal mine emergency exercise was restricted by environment with high cost and hidden danger, and existing coal mine emergency exercise system failed to consider multi-person coordination. In view of above problems, combining with application requirements of multi-person coordination in coal mine emergency exercise, a multi-person cooperative emergency exercise system in coal mine was designed, which included presentation layer, service layer and storage layer. By simulating and reproducing real mine environment and disaster scenario, multi-department and multi-person are organized to conduct collaborative exercise in the same space and time dimension. The pilot application results show that the system can meet nearly one hundred persons simultaneously conduct online collaborative emergency exercise, which effectively improves ability of participants to deal with disaster and cooperate with each other.
