| 中文摘要: |
| 在非煤矿山中,许多矿山因矿石含硫量高,在开采过程中经常发生矿石自燃火灾。因此,开展采场矿石自燃危险性评价意义重大。作者通过总结以往的评价方法,并在做了大量实验的基础上,建立了针对硫化矿石氧化自燃危险性的综合评价体系。首先,以“火灾、爆炸危险指数评价法”(DOW)为模型,根据影响硫化矿石自燃的因素分析,建立了针对硫化矿石自燃危险性的评价指数和等级。据此,结合新疆某矿的矿石自燃性开展评价。作者在评价过程中,考虑了该综合评价法在矿山生产中的实用性,评价方法中的各个影响因素都可以通过实验或者现场调查确定其应取的危险值,这种评价方法适用于所有的硫化矿山火灾危险性评价。 |

| During mining of sulfide ores at non-coal mines, there are many spontaneous fire accidents due to ores with rich sulfide. Therefore, it is very significant to develop an effective risk assessment technique. In this paper, the authors summarized existed assessment methods of spontaneous fire of sulfide ores, and established a new risk assessment system based on experiments and literature review. The authors applied the assessment method of the fire and explosion index evaluation of DOW company to analyze the dangerous factors that may cause spontaneous fire accidents of sulfide ores. Accordingly, all relevant indexes at various dangerous ranks were put forward on referring the mining field situations. Furthermore, the assessment method was applied for assessing the fire potential of a mine with sulfide ores in Xinjiang. In the evaluation process the practicality in the production of the mines is considered. All the dangerous factors can be obtained from experiments or investigations of mining site. The risk assessment system can be applied to all the sulfide mines. |
