    摘要:

    冲击地压评价指标具有灰度、模糊性等特点,难以确定合理的指标权重,致使传统的评价方法精度较低,无法满足工程需要。针对此问题,基于集对分析和区间三角模糊数,构建了SPA-ITFN冲击地压评价模型。集对分析中多元联系数可以兼顾评价指标的确定性和不确定性,区间三角模糊数使得等级之间界定更加准确;构建了以开采深度、采煤方法等12个指标的冲击地压评价指标体系。利用新评价模型,对某煤矿六个工作面进行冲击危险性评价,评价结果与模糊综合评价、基于云模型和D-S理论的评价模型对比分析。结果表明:SPA-ITFN冲击地压评价模型评价合理、准确,并且精度较高,对煤矿冲击地压的监测和预报具有较高的参考价值。

    Abstract:

    The evaluation index of rock burst has the characteristics of grey scale and fuzziness, so it is difficult to determine the reasonable index weight, resulting in the low accuracy of the traditional evaluation method, which can not meet the needs of the project. To solve this problem, based on set pair analysis and interval triangular fuzzy number, the SPA-ITFN evaluation model of rock burst was constructed. In the set pair analysis, the multivariate connection number can give consideration to the certainty and uncertainty of the evaluation index, and the interval triangular fuzzy number makes the definition between the grades more accurate. The evaluation index system of rock burst was constructed, which includes 12 indexes, such as mining depth, mining method and so on. The new evaluation model was used to evaluate the rock burst risk of six working faces in a coal mine. The evaluation results were compared with the fuzzy comprehensive evaluation, the evaluation model based on cloud model and D-S theory. The results show that the SPA-ITFN rock burst evaluation model is reasonable, accurate and the precision is high, and the evaluation results have high reference value for the monitoring and prediction of coal mine rock burst.
