中文摘要：
利用灰色效果测度理论对影响矿石自燃的各因素进行灰色效果测度，并结合相对重要程度相关等级计算法得到的矿石自燃各影响因素权重矩阵进行模糊关系合成，得到灰色效果综合测度值，将灰色效果综合测度值与矿石自燃情况进行对应分析，得到矿石自燃规律，为矿山提前采取应对措施、减少损失提供了科学依据，实践证明，该方法科学可行。
英文摘要：
Grey effect measure theory was applied to measure gray effect of factors affecting ore combustion, fuzzy relation syn thesize was made on the weight matrix of affecting factors of ore spontaneous combustion,which was obtained by relevant grade calculation of relative importance degree, and grey comprehen sive measure values of the affecting factors were obtained. Then, the correspondence analysis of the grey comprehensive measure values and the states of ore spontaneous combustion was carried out, and the rule of ore spontaneous combustion was presented. It provided scientific basis for the mine to reduce losses by taking ahead counter measures. Practice has proved the scientificity and feasibility of the method.
