矿井主要通风机联合运转安全性研究

Study on Safety of Combined Operation of Main Mine Ventilator

介绍了改扩建矿井不同型号的通风机,在投入联合运转前,通过对通风机性能测试和矿井通风阻力测试,采用由日本专家编制的"风丸"通风网络解算程序,进行模拟演示,找出工况点,对井下通风系统和通风机运行进行安全性分析,从而确保了主要通风机联合运转的安全可靠性。

Before the different types of ventilators used at an expanded coal mine are put into joint operation,experiments are made to determine the performance of individual ventilators and the ventilation resistance.Following that,simulation demonstration is made on their combined operation using the Fengwan ventilation network solution program developed by Japanese expert to determine the ventilators' optimal working condition,as well as the operational safety of underground ventilation system and ventilators.Analysis shows that the safety of the combined operation of the main ventilators can be ensured
