为确定王行庄煤矿二_1煤层突出危险性预测敏感指标及其临界值,在现场考察基础上,采用临界度理论建立了确定突出敏感指标的理论模型,分析了突出预测指标的敏感性,确定了突出预测敏感指标,最后通过“三率”法和实验相结合综合确定了各敏感指标的具体临界值。
In order to determine the sensitive index and its critical value for the prediction of prominent coalition risk in Wanghangzhuang Coal Mine, a theoretical model for identifying the prominent sensitive indicators was established based on the field investigation. The sensitivity of the predictor was also analyzed and the criticality was determined Highlighting the predictive sensitivity indicators, and finally by the “three rate” method and the combination of experiments to determine the specific threshold of the sensitive indicators.
