| 摘 要： | 基于煤与瓦斯突出机理，构建了煤巷掘进工作面煤与瓦斯突出的简化力学模型，通过力学分析，提出了以瓦斯压力为主要指标的突出判式。根据突出预测指标K 1与瓦斯压力之间的关系，推导出突出敏感指标K 1的临界值。结合山西华晋焦煤有限公司沙曲煤矿的实际情况，确定了沙曲煤矿突出敏感指标K 1的临界值为0.5，煤层出现构造破坏时，临界值为0.3。

Research on the prediction indexes of coal roadway heading face outburst and its critical value |
| |
| Abstract: | Based on the coal and gas outburst mechanism,simplified the outburst mechanical model of coal roadway heading face.Through mechanical analysis,put forward by the gas pressure as the main index of prominent sentenced to type.According to the relation of the predict index K 1 and gas pressure,deduced the critical point K 1.Combining the pratice of Shaqu Coal Mine of Shanxi Huajin Coking Coal Co.,Ltd.,usually critical value is 0.5,specially,when the coal steam is damaged,the standard is 0.3. |
