摘要
选择影响煤层自燃发火的主要因素:煤的自燃倾向性、煤层的地质赋存条件、开采技术条件,通风条件和预防措施等进行主观判断,分类评分.应用模糊数学理论,运用逐步聚类分析法,根据标准模式,计算聚类中心,对生产采区煤层自燃发火的危险进行综合预测.为拟定相应的开拓开采方案,制定有效的防火措施,提供一种切合实际情况的新方法.
The risk level of spontaneous firing of the coal seam in the mining arca thoroughly assess- ed by sublectively idertifying,cla■ssifying and scoring the main factors affecting the firing. In the assessment,the stepwise cluster analysis method and standard model of the fuzzy mathem- atics to calculate cluster center are employed.This paper offers a practical technique for making an appropriate mining program and effective fire protection measures.
