深部开采中矿井煤岩动力灾害表现形式复杂且受多种因素影响。在综合分析各影响因素基础上,找出预测敏感指标并将危险性划分等级,提出了基于UOWA算子煤岩动力灾害预测方法。该方法能够将定性指标与定量指标有机地统一起来,并解决了预测指标为区间数的预测问题,提高了预测的准确性和可操作性。通过在平煤八矿戊9.10-12160工作面的现场应用,验证了该方法的可行性。
The performance of coal and rock power disasters in deep mining is complex and affected by many factors. Based on comprehensive analysis of various influencing factors, the index of predictive sensitivity is found and the grade of danger is classified. A coalmine dynamic disaster prediction method based on UOWA operator is proposed. The method can organically unify the qualitative index and the quantitative index, and solves the prediction problem that the forecast index is the interval number, and improves the forecasting accuracy and the operability. The feasibility of this method is verified by the field application in the No. 9.10-12160 face of Pingdingshan No.8 Mine.
