我国许多高硫、高温矿山大都存在自燃发火倾向,甚至在开采期间出现过不同程度的高温自燃现象。在这类高硫、高温矿床的开采过程中涉及到高温爆破安全问题,当硝铵炸药(2~#岩石炸药)直接装进高温硫化矿炮孔后,硝酸铵与硫化矿接触发生激烈放热反应并最终导致炸药自燃、自爆,从而严重
Most of China’s high-sulfur, high-temperature mines spontaneous combustion tendency most exist, even during the mining there have been different degrees of high temperature spontaneous combustion phenomenon. During the mining process of such high-sulfur and high-temperature deposits, high-temperature blasting safety problems are involved. When ammonium nitrate explosives (2-# rock explosives) are directly charged into the blast holes of the high-temperature sulphide mine, intense contact of the ammonium sulphate with sulphide ore occurs. Reaction and eventually lead to spontaneous explosives, blew, and thus serious
