摘要: 基于突变理论和模糊数学相结合的突变级数法,提出了冲击地压危险性评价的新指标—突变级数;通过综合考虑冲击地压危险性影响因素,建立了新的冲击地压危险性评价模型;在对各影响要素进行了无量纲化和归一化处理的基础上,利用煤矿现场数据对模型进行了样本学习,确定了不同冲击危险等级的突变级数,并结合已有数据对模型进行了验证。将评价模型应用于工程实例,并与其它主要评价方法比对,结果表明:该方法评判结果准确,精度较高,具有良好的实用价值。

Abstract: In this paper, based on the catastrophe progression method which combining the catastrophe theory and the fuzzy mathematics, a new catastrophe progression index to evaluate rock burst was proposed. Meanwhile, by comprehensive considering of the influence factors of rock burst risk, a new evaluation model of rock burst was built. In addition, after the nondimensionalization and normalization processing of the influencing factors, the sample learning on the model was conducted according to the field data in coal mine, the catastrophe progressions of different burst risk grades were ascertained, and the model was verified by using the existing data. Finally, the evaluation model was applied to engineering practice, and was compared with other evaluation methods. The results show that this method has accuracy evaluation results, high precision and good practical value.
