摘　　要：依据流体力学紊流变形理论,讨论了现有独头巷道爆破掘进通风风量计算方法存在的不足;结合现行标准,推出了新的爆破掘进风量计算公式,并以现场实测数据进行了验证。结果表明,新推导的爆破掘进风量计算公式的计算结果与实际风量更接近,所反映的规律更符合实际情况。Based on the turbulent deformation theory of fluid mechanics,the shortcomings of the existing calculation method of air volume required for the ventilation in the blasting and driving of dead-end drift were discussed.Combined with the current standard,a new calculating formula for the air volume was proposed and also verified by the on-site measured data.The results show that the calculation results of the newly derived formula are closer to the actual measured air volume,indicating that it is more in line with the actual situation.
