【摘要】 在井下爆破材料库的安全性评估中，如何计算巷道中的空气冲击波超压值尤为重要。本文介绍了一种计算井下巷道中空气冲击波超压值的计算模型和计算方法，此方法用于井下爆破材料库安全评估计算能得到较为准确的结果，可以判断发生事故的可能及危害程度，为采取预防措施提供了依据。在不违反现行《爆破安全规程》的前提下，文章还提出了修改井下爆破材料库的设计方案更多还原

【Abstract】 In the safety assessment of the underground explosive magazine, it is very important to calculate the superpressure of the air shock wave which spreads in the drift. This paper introduces a calculation method of the superpressure. Better results can be obtained when this method is used for the safety assessment of underground explosive magazine. It can be used for determining the possibility of accident occurrence and the harm degree, which provides the basis of taking precautions. An improved design scheme of underground explosive magazine, which doesn’t violate the rules for the blasting safety, is also put forward.更多还原
