摘要
为客观评价煤矿煤与瓦斯突出危险性,合理确定各影响因素权重,基于改进熵权法及未确知测度理论建立煤矿突出危险性评价模型.选取4个评价指标,采用改进熵权法计算权重值,结合未确知测度理论计算天安十三矿的多指标综合测度评判向量,最后根据置信度识别准则确定天安十三矿的3个样本地点的突出危险性评价等级.将评价结果与现场实际情况进行对比可知评价等级符合实际.因此,利用所提出的模型进行突出危险性评价十分有效,可以为煤矿突出危险性评价工作提供参考.
In order to objectively evaluate the risk of coal and gas outburst in coal mines and reasonably determine the weight of each influencing factor,an evaluation model of coal mine outburst risk is established based on the improved entropy weight method and the undetermined measurement theory.It selects 4 evaluation indicators,uses the improved entropy weight method to calculate the weight value,and calculates the multi-indicator comprehensive measurement evaluation vector of Tian an No.13 Coal Mine in combination with the undetermined measurement theory.Finally,it highlights the risk assessment level of this above mine.Comparing the evaluation results with the actual situation on site,it can be seen that the evaluation level is in line with the actual situation.Therefore,it is very effective to use the proposed model to evaluate the outburst risk.It can provide reasonable suggestions for the prevention and control of coal and gas outburst according to the weight value of the influencing factors,which can provide references for the evaluation of the outburst risk of coal mines.
