金属矿山开采之前开展硫化矿石自燃倾向性测试是预防矿山自燃火灾发生的重要手段之一。本文系统论述了硫化矿石自燃倾向性测试方法的研究成果,着重评述了硫化矿石自燃倾向性判定的吸氧速度法、传统的交叉点温度法、动态自热率测试法、绝热氧化法、金属网篮交叉点温度法、综合测试法、程序升温氧化法,以及TG-DSC联用法等。对其中某些方法的测试原理、操作步骤,以及存在的优缺点进行分析,将各种方法进行归纳分类,并对硫化矿石自燃倾向性测试方法的研究方向进行了展望。

Evaluating spontaneous combustion tendency of sulfide ores before actually mining is one of the most effective measures for preventing metal mines from causing spontaneous combustion fires. The present test methods for assessing spontaneous combustion tendency of sulfide ores, including oxygen-adsorption velocity test, traditional crossing-point temperature test, adiabatic oxidation test, comprehensive test, wire-mesh basket crossing point temperature method, temperature programmed oxidation method, and TG-DSC test, are systematically discussed. The test mechanism, operation procedures, excellences and drawbacks for some test methods are set forth. Based on the characteristics of these methods, five types of them are classified, and the future development direction for the spontaneous combustion tendency test of sulfide ores is also looked into.
