摘要
分析研究了工作面煤与瓦斯突出危险性与瓦斯涌出特征值之间的相关关系,通过提取瓦斯涌出量平均值、最大值以及落煤瓦斯浓度数据斜率作为瓦斯涌出特征值,结合煤与瓦斯突出危险性指标,提出了工作面煤与瓦斯突出危险性与瓦斯涌出特征值回归分析方法。实例应用验证了该方法的有效性。
Relationship of coal and gas outburst risk and gas emission characteristic value on mining face was analyzed.Through taking the average and maximum amount of gas emission and data slope of gas concentration of fallen coal as gas emission characteristic value,a regression analysis method of coal and gas outburst risk and gas emission characteristics value on mining face was proposed combining with coal and gas outburst risk indicators.The application of examples shows validity of the method.
