为确定煤层的突出危险性,在对某煤矿主采煤层掘进考察区的突出预测敏感指标考察过程中,采用“三率法”对某煤矿主采煤层掘进考察区的突出预测敏感指标及其临界值进行研究分析。研究结果为保证突出煤层掘进巷道作业的安全性提供了保障,具有很高的实用价值。
In order to determine the prominent danger of coal seams, the “Three-rate method” is used to highlight the outstanding predication of the main coal mining area in a certain coal mine Indicators and their critical value for research and analysis. The results provide a guarantee for the safety of the working face of outburst coal roadway and have high practical value.
