摘要
根据瓦斯爆炸理论和顶板垮落规律,对铜川矿务局陈家山矿11.28特大瓦斯事故中的瓦斯爆炸量、爆炸热量及爆炸热当量(相当于梯恩梯炸药的爆炸热量)进行了估算,以期达到瓦斯爆炸事故定量评判的目的。其估算结果为:参与爆炸的瓦斯量为22331m3;爆炸热量为8.27×1011J;爆炸热当量相当于197.6t梯恩梯炸药的爆炸热量。
According to damp explosion theory and roof fall rule, the paper estimate damp amount, heat amount and heat equivalent （to be equal to heat amount of 1 ton of TNT explosive） of a big accident happened in Chenjiashan Mine on 28th, Nov. ,2004. The aim is to judge the scale of damp explosion for the future. The result is as fullow： explosion amount 22331m^3, explosion heat amount 8.27 × 10^11J, explosion heat equivalent is TNT explosive 197.6t.
