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。
Based on the catastrophe series method combining catastrophe theory and fuzzy mathematics, a new index of catastrophic ground pressure hazard evaluation, ie, the number of catastrophic changes, is proposed. By considering the risk factors of rockburst, a new risk of rockburst Based on the non-dimensional and normalized treatment of each influencing factor, the model was studied by using the on-site data of coal mines, and the number of abrupt change of different impact hazard levels was determined. Combined with the existing data The model is validated. The evaluation model is applied to engineering examples and compared with other major evaluation methods. The results show that the method is accurate, accurate and has good practical value.
