摘　　要：本文在文献[1]的物理模型基础上,采用量纲分析法,导出了空气冲击波沿井巷传播规律的基本关系式,并用巷道中心爆炸的实测数据进行了拟合,得到了空气冲击波沿井巷传播规律的经验关系式。Based on the physical model developed in the literature, a basic formula is derived for the propagation regulation of air blast waves during shafts and tunnel blasting by means of a dimensional analysis. On the basis of this formula, a aecourate formula for describing the propagation of air blast wave is derived by processing the data acquired under the conditions of explosion in the centre of an experimental tunnel.
