【摘要】：为分析总结多级机站通风方式实际应用中存在的影响通风效果的共性问题,以某大型机械化铁矿通风系统为研究对象,应用能适用多台风机串并联运行的"矿井通风三维仿真系统(简称3DVS)"软件进行应用研究。结果表明,3DVS软件可以快速地实现多级机站通风系统中不同型号多台风机联合作业下的风机选型。采用安装在运输巷道两侧的硐室型风机机站技术能有效解决大压差、大断面运输巷道不安装风门、不掘绕道设置风机机站的关键问题,实现风流有效分配,且具有较好的灵活性,其成功应用,不但为多级机站通风方式的应用提供了技术和经验支持,而且增强了多级机站通风方式的适应性和稳定性,可以减少风机机站维护工作量,不影响行人和运输,促进多级机站技术发展与推广。
[Abstract]:In order to analyze and sum up the common problems existing in the practical application of ventilation mode of multistage machine station, the ventilation system of a large mechanized iron mine is taken as the research object. The application of 3DVS software, which can be used in series and parallel operation of multi-typhoon machines, is studied. The results show that the 3DVS software can quickly realize the type selection of fans under the combined operation of different types of multi-typhoon machines in the ventilation system of multi-stage stations. Adopting the technology of chamber fan station installed on both sides of transport tunnel can effectively solve the key problems of large pressure difference, large section transportation roadway not installing air door, no driving and bypass setting fan machine station, and realizing the effective distribution of air flow. It has good flexibility. Its successful application not only provides technical and empirical support for the application of multi-stage fan station ventilation mode, but also enhances the adaptability and stability of multi-stage engine station ventilation mode, and can reduce the maintenance workload of fan station. Do not affect pedestrian and transportation, promote the development and promotion of multi-stage station technology.
