摘要
鉴于矿井巷网火灾烟流自由蔓延易造成人员窒息死亡的现状,分析了典型运输巷胶带或电缆火灾烟流的运移特征,探讨了风烟流快速隔离排出路径.提出了分布式联动通风设施的智能化调控方法,结合井下灾变环境和破坏效应融合了多源冗余技术,保障停电、压风破坏、通信中断条件下冗余组件间自动切换.构建了多元灾变信息交叉感知与态势研判模型,通信异常或中断时,按"远程控制+联动决策+自主决策"多重保险模式实现灾变联动.融合故障预测与健康管理(PHM),提高灾变联动系统综合可靠性.分析了系统可靠性影响因子,建立了故障树并转化为贝叶斯网络结构,按照正向分析确定了无冗余系统的可靠度为80.3%;贝叶斯反向推理供电、压风、通信模块导致系统故障的概率分别为40.6%,40.6%和20.3%;多重冗余条件下系统综合可靠度达97.3%.证明了系统冗余设计的必要性和可行性,为灾变风烟流应急调控技术装备的工程应用提供指导.
In view of the current situation that the free spread of the fire smoke flow in mine road network can cause suffocation and death,the characteristics of a typical transportation lane belt or cable fire smoke flow was analyzed,and the rapid isolation and discharge path of the wind and smoke flow was discussed.An intelligent control method for distributed linkage ventilation facilities was proposed,combined with underground catastrophic environment and destructive effects,multi-source redundancy technology was incorporated to ensure automatic switching between redundant components under conditions of power outage,pressure wind damage,and communication interruption.A model for cross-sensing and situational judgment of multiple catastrophic information has been constructed.When communication was abnormal or interrupted,disaster linkage could be realized according to the multiple insurance model of remote control,linkage decision-making and independent decision-making.This paper integrated fault prediction and health management(PHM)to improve the comprehensive reliability of the disaster linkage system.We analyzed the system reliability influencing factors,established a fault tree and transformed it into a Bayesian network structure.According to the forward analysis,the reliability of the non-redundant system was determined to be 80.3%.On the basis of Bayesian reverse inference,the probability of system failure caused by power supply,compressed air,and communication modules was 40.6%,40.6%and 20.3%,respectively.The comprehensive reliability of the system under multiple redundancy conditions reached 97.3%.It proves the necessity and feasibility of the redundant design of the system,and provides guidance for the engineering application of emergency control technology and equipment for catastrophic wind and smoke flow.
