矿山突(透)水灾害应急疏散模拟系统与工程应用

Emergency evacuation simulation for water bursting disaster in mine

  • 摘要: 矿山突(透)水灾害发生时,井下人员合理应急疏散是有效避免矿井群死群伤事故的重要举措。根据矿山突(透)水灾害应急疏散模拟需求及各种复杂影响因素分析,基于物联网的数据采集与识别,构建矿井地质环境与井下场景;通过突(透)水点及其相关信息获取、巷道水流模拟、人员逃生行为模拟、以及智能动态路径搜索,在VR仿真环境中进行应急疏散模拟及可视化分析,实现个体或群体行为动态过程模拟,生成安全迅速的井下人员最优疏散路径。针对应急疏散决策和疏散演练分析,进行定性定量评价与预警。经过在矿山实际工程应用,效果较好,为矿井灾害情景下的人员合理疏散、应急救援和人员培训等提供辅助决策支撑平台。

     

    Abstract: Emergency evacuation of underground personnel is an important safety measure when a water disaster occurs in a mine. In this paper,according to the demand of the simulation for emergency evacuation and the analysis of vari- ous complex influencing factors,the geological environment and the underground scene of the mining area are construc- ted based on the data acquisition and identification of the Internet of Things. The simulation and visualization of emer- gency evacuation in VR simulation environment is carried out through the information acquisition of water bursting points,the simulation of roadway flow and behavior of evacuees and intelligent dynamic path search. This method achieves a dynamic process simulation of individual or group behavior as well as generates safe and rapid evacuation routes. Qualitative and quantitative evaluation and early warning are conducted for emergency evacuation decisions and evacuation exercises. The method has been used in mine,and the results show that it can provide an auxiliary decision- making platform for personnel evacuation plan,emergency rescue and personnel training under the situation of mine disaster.
