本文根据硫化矿石装药后引起自爆的情况,对各类硫化矿石进行炸药与矿石接触试验;对矿石的某些物理化学性质进行测试,从理论与实践中研究分析和评价了各类矿石的自爆危险程度。本文还对白银小铁山铅锌矿、江西武山铜矿、浙江建德铜矿等有自爆危险的矿山,作了鉴别炸药自爆危险程度评价的实例介绍,提出了预防炸药自爆危险的基本措施。
In this paper, according to the situation of spontaneous explosion caused by sulfide ore loading, various types of sulphide ores were tested for the contact of explosives and ores; some physical and chemical properties of ores were tested, and theoretical and practical studies were carried out to analyze and evaluate the types of ores Dangerous level This paper also made an example introduction to the appraisal of the dangerous degree of explosive detonation in the mine with risk of detonation, such as the small silver Tieshan lead - zinc mine in Jiangxi province, the Jiangxi Wushan copper mine in Zhejiang province and the Jiande copper mine in Zhejiang province, and put forward the basic measures to prevent the explosion danger of explosives.
