| 摘 要： | 科学地进行“以风定产”，是实现高瓦斯矿井安全生产的重要保证和前提之一。本文选定矿井通风系统相对稳定的时期为核定时期，通过矿井需要风量计算，确定各采掘工作面、硐室及备用工作面的需风量；根据矿井通风能力计算，确定安兴煤矿合理的采掘比为1：3，矿井通风能力为120万吨。并从矿井通风动力、用风地点有效风量、矿井通风网络能力、稀释瓦斯能力等方面验证了矿井通风能力为120万吨。井下各用风地点风流稳定，风量、风速、风阻满足要求，矿井通风网络能力能够满足生产安全的要求

| Abstract: | A relative stable period of the mine ventilation system was selected as a rated period.With the calculation on the required ventilation value of each mining and excavation face,chamber and standby working face in Pingtu Mine,the mine required ventilation value could be set up.According to the calculation of the mine ventilation capacity,the rational mining and excavation ratio of the Pingtu Mine determined was 1∶ 3 and the mine ventilation capacity was 1.20 million t/a.The mine ventilation capacity of 1.20 million t/a was verified with the mine ventilation power,the effective ventilation value at the required ventilation place,mine ventilation network capacity,diluted gas capacity and others. |
