摘　　要：为了使通风系统满足“2采6掘”的生产模式,利用地质数学模型对煤层瓦斯含量进行了预测,实测结果证明了模型的准确性。基于预测模型,本着以风定产的原则对通风系统进行了调整和优化,优化后的通风系统降低了通风阻力,增加了风量的供给,满足“2采6掘”的生产模式,达到了安全通风的目的。基于矿井瓦斯积聚特征,对通风系统的调整优化进行了探讨。In order to make the ventilation system meet the production mode of"2 minings and 6 excavations",the gas content in coal seam was predicted by using geological mathematical model,and the measured results proved the accuracy of the model.Based on the prediction model,the ventilation system was adjusted and optimized based on the principle of ratifying production by wind.The optimized ventilation system reduces the ventilation resistance,increases the supply of air volume,meets the production mode of"2 minings and 6 excavations",and achieves the purpose of safe ventilation.Based on the characteristics of mine gas accumulation,this paper discussed the adjustment and optimization of the ventilation system.
