| 摘 要： | 深部持续采动诱发的断层活化滑移过程具有灰色系统的特征。基于某铜矿深部开采诱发断层活化滑移的现场实测数据,构建了GM(1,1)灰色预测模型。通过断层预测滑移量与实测滑移量对比分析,模型具有较高的精度。运用所构建的断层活化滑移灰色预测模型,对未来四期断层滑移量进行了预测,F2断层滑移量增速较快,与现场实际情况吻合。研究成果对于深部复杂采动影响下断层活化滑移量的预测具有重要的意义。

| Abstract: | The process of fault activation and sliding induced by deep continuous mining is characterized by grey system. The GM (1,1) grey prediction model is established based on the field measurement data of fault activation slip induced by deep mining in a copper mine. By comparing the predicted and measured slip values of faults, the model has high accuracy. The grey prediction model of fault activation slip is used to predict the future four phases of fault slip. The growth rate of F2 fault slip is fast, which is consistent with the actual situation in the field. The research results are of great significance to the prediction of active slip under the influence of complex deep mining. |
