摘要
为了确定谢桥矿煤与瓦斯突出敏感指标及其临界值,采用"三率"、模糊聚类分析法对其进行分析,确定其临界值。通过对其掘进工作面突出危险性预测指标的测定,得出了其敏感性的排序:S>q>K1;突出预测敏感指标:钻屑量指标S临界值为6.0 kg/m,q值临界值为4.0 L/min。
In order to define the sensitive index and the critical value of coal and gas outburst in Xieqiao Mine,the outburst sensitive index is analyzed by the three ratio method,fuzzy clustering,and the critical value is defined.With the tracking and measurement of the prediction indexes for the outburst danger at the heading face of the seam gateway in Xieqiao Mine,the prediction index sensitivity with a sequence of SqK1 of the outburst danger in Xieqiao Mine was obtained.The critical value：the cutting quantity S was 6kg /m and q was 4.0L/min.
