【摘要】 本文采用差热分析法（DTA）对句容硫铁矿矿石自燃点进行了测试，并与其它易燃物的自燃点进行比较。作者还对该矿石与不同品种炸药接触的化学安定性进行了试验。结果表明，该硫化矿石具有自燃倾向，炸药与其接触具有自然自爆危险。更多还原

【Abstract】 The spontaneous combustion points of the sulfide ores that come from Jurong Sulfide iron Mine has been determined by DTA and compared with those of other combustibles in this paper. The chemical safety when these ores contact with varieties of explosives has also been studied. The results show that these ores have the tendency to combust spontaneously and the ammonium nitrate explosiveswhich contact with the ores have the risk of spontaneotis combustion or explosion.更多还原
