摘　　要：针对煤矿矿井事故发生率高、后果严重的问题,为了能够更好地了解矿井发生灾害后的灾害详情,更加有效地进行灾害防治与控制,创造性地提出了利用示踪气体技术模拟不同灾害状态下的矿井通风状态,风流流量和示踪气体体积的变化。通过建立实验装置对示踪气体的测量,从而模拟示踪气体在实际不同灾害下的数值,研究总结示踪气体在不同灾害状态下的变化规律。根据示踪气体在不同灾害的变化趋势规律,了解灾害的状态和严重程度,提出有效的灾害防治措施,极大地保证了作业人员的安全,并降低灾害防治的难度,提高灾害救援效率。In response to the high incidence rate and severe consequences of coal mine accidents and to better understand disaster details after occurrence,this study proposes an innovative approach using tracer gas technology to simulate mine ventilation conditions and changes in airflow and tracer gas volume under various disaster scenarios.An experimental apparatus was established to measure tracer gas,simulating numerical values under different actual disaster conditions.The study summarizes the variation patterns of tracer gas under the diverse disaster states.By analyzing these trends,the research aims to understand the state and severity of disasters,proposing effective prevention and control measures that could enhance the safety of operating personnel,reduce the difficulty of disaster prevention,and improve disaster rescue efficiency.
