1、前言煤矿中使用的雷管对沼气安全度的检定已进行了广泛的探讨,而对煤尘安全的检定,尚有很多不明之点。这种雷管混留在煤矿采区中并随着采区煤炭送到用户时,有发生爆炸或因某种原因成为引燃带有可燃气体的起爆原因等问题。例如,在火力发电厂的锅炉中使用时,是用80～150℃的热风将粉煤形成浮游粉煤状态送入炉中燃烧的,雷管在这种高温浮游粉煤中起爆时,能否引起煤尘爆炸是有必要加以研究的。为此,在上述条件下,关于雷管起爆时是否能形成煤尘 1. Foreword The detonator used in coal mines has extensively explored the verification of biogas safety. There are still many unclear points about the verification of coal dust safety. This detonator mixed in the coal mining area and with the coal mining area to the user, there is an explosion or for some reason as ignition with a combustible gas detonation causes and other issues. For example, when used in a boiler of a thermal power plant, the pulverized coal is fed into a furnace for burning with a hot air of 80 to 150 ° C. When the detonator is detonated in such a high-temperature pulverized fly ash, can it cause It is necessary to study the coal dust explosion. For this reason, in the above conditions, whether the formation of dust on detonator detonation
