高原煤矿瓦斯事故疏散模型及动态算法研究

Evacuation model and dynamic algorithm of plateau mine gas accident

针对青海省煤矿企业在瓦斯事故出现后应急疏散面临空气稀薄、大气压力低等特殊环境,引入K短路概念,从多疏散点和不同海拔高度空气氧含量不同两个方面,建立了适合高原地区煤矿瓦斯事故发生后的人员疏散模型,设计了基于图论中网络优化思想的动态算法。结果表明:该模型及算法将为高原地区煤矿瓦斯事故应急救援决策、应急救援实施及应用提供技术支撑,提高高原地区煤矿企业抗灾、减灾能力。

Considering thin air and low atmospheric pressure in the emergency evacuation of plateau mine enterprises,K-shortest path has been introduced.Emergency evacuation model of plateau gas accident has been established from the perspective of multiple evacuation points and different oxygen content in the air with different altitude,and dynamic algorithm has also been designed based on graph theory and network optimization.The results show that the model and algorithm will support emergency decision-making and emergency rescue in plateau mine enterprises,improve ability of disaster prevention and mitigation of plateau mine enterprises.
