冲击地压 综合评价 指标体系 模糊数学 隶属度
为解决冲击地压危险性难以准确预评价的难题,提出冲击地压危险性评价的一个新指标-模糊层次指标;采用专家评分的方法优化冲击地压评价指标,建立合理的冲击地压评价指标体系及模糊层次综合评价模型,并在指标分级量化、权重AHP分析和隶属度比值法确定的基础上,运用二级模糊综合评价法对评价模型进行计算,研究巷道、工作面乃至整个矿井的冲击地压危险性;模型应用于工程实例的结果表明:该方法评价结果准确、可靠,具有良好的应用价值.%In order to solve the problem that rock burst hazard is difficult to accurately evaluate,we propose a new indicator of rock burst hazard evaluation fuzzy hierarchy index,use expert evaluation method to optimize rock burst evaluation index,establish reasonable evaluation index system of rock burst and fuzzy hierarchy comprehensive evaluation model. On the basis of grade indexes,AHP analysis weights and ratio method determining membership degree,we finally use the secondary fuzzy comprehensive evaluation method to calculate model of roadway,working face and the whole mine rock burst hazard. The results of engineering examples show that the methods of evaluation results are accurate,reliable and valuable.
