摘　　要：为适应新工科背景下实验室建设对气固耦合模拟实验设备的性能以及智能化与安全性需求,研发了大流量高压气体充填教学实验系统。该系统包括气源模块、动力模块、气体增压模块、储气模块、真空模块、气体充填模块、采集控制模块,解决了现有仪器在气体充填过程中存在的低温效应,可实现0~10L/s、0~5 MPa气体的恒体积流量、恒压充填,并可通过同一套软件实现整个系统的自动化控制与数据采集。最后,通过巷道掘进诱发的煤与瓦斯突出物理模拟实验验证了该系统的可靠性与精确性。In order to meet the performance,intelligence,and safety requirements of gassolid coupling simulation experimental equipment in the context of new engineering disciplines,a gas filling experimental teaching system with high flow rate and constant gas pressure is developed.The system includes a gas source unit,a power unit,a boost unit,a gas storage unit,a vacuum unit,a gas filling unit,and an information collection and control unit,which solves the lowtemperature effect existing in the gas filling process of existing instruments.It can achieve constant gas speed(0~10 L/s)and constant gas pressure(0~5 MPa)filling,and can achieve automatic control and data collection of the entire system through the software.Finally,the reliability and accuracy of the system are verified through physical simulation experiments of coal and gas outburst induced by tunnel excavation.
