摘要
本文通过对影响煤矿许用毫秒延期电雷管瓦斯安全性各因素的试验分析,总结出主要影响瓦斯安全性的两个因素是雷管的主装药量和铅延期元件的发火热量。
By analyzing the various factors affecting the gas safety of permitted millisecond delay electric detonator for coal mine, this paper summed up the main two factors that affect the gas security： the detona- tor explosive charge and the combustion heat of delay element of lead.
