摘 要:为了确定煤与瓦斯突出敏感指标及其临界值,防止敏感指标临界值的过大过小导致突出现象的发生。选取平煤九矿作为实验地,运用"三率"法对其进行定量分析,确定钻孔瓦斯涌出初速度q和钻屑量指标S为突出敏感指标,并确定了预测敏感指标的临界值。实践表明,该预测敏感指标能有效地解决突出指标的难题,对指导现场安全生产具有一定的意义。In order to determine the sensitive index of coal and gas outburst and its critical value, prevent sensitive indicators of the critical value great or small led to outburst. No. 9 Mine of Pingdingshan Mining Industry was taken as sample, "Three-rate"was applied to do quantitative analysis, drilling hole gas emission velocity q and drilling cuttings volume index S were sensitive index of the mine, the critical value of predicting sensitive indicator was settled. The practice showed that predictive sensitive indicators could effectively solve the problem of outburst index, with great significance for guiding the site safety.
