摘要
通风系统在井下生产活动中尤为重要,为了提高矿山应急救援演练的真实性,结合煤矿应急演练的需求,基于网络数据模型技术,在应急演练系统中应用矿井通风网络模型,模拟井下气体相关灾害的演变过程。在应用中,利用风流在井下的扩散特点和烟流的扩散规律,还原了有害气体的扩散情况。人为对通风系统的调节,会使风流动态变化,进而影响有害气体的扩散过程。通过应用的研究,真实还原了应急演练中火灾、煤尘灾害、瓦斯灾害等与气体紧密相关的灾害的影响范围,为提高演练的真实性起到关键作用。
Ventilation system is particularly important in underground production activities.In order to improve the authenticity of mine emergency rescue drill,combined with the needs of coal mine emergency drill,based on network data model technology,mine ventilation network model is applied in the emergency drill system to simulate the evolution process of underground gas related disasters.In application,the diffusion of harmful gas is reduced by using the diffusion characteristics of air flow and smoke flow underground.The artificial regulation of the ventilation system will make the air flow change dynamically,and then affect the diffusion process of harmful gases.Through application research,the impact range of fire,coal dust disaster and gas disaster in emergency drill is truly restored,which plays a key role in improving the authenticity of drill.
