梁北煤矿煤与瓦斯突出主控因素分析

Analysis on Main Controlling Factors of Coal and Gas Outburst in Liangbei Coal Mine

煤与瓦斯突出主控因素与煤巷掘进敏感指标的选择具有相关性。通过对梁北煤矿历年煤与瓦斯突出特征、矿井地质构造与瓦斯含量的相关性和实验室煤样参数测定等进行综合分析,确定了煤与瓦斯突出主控因素;根据其相关性在后期进行了现场煤巷掘进工作面敏感指标考察的相关验证,为类似突出矿井煤巷掘进工作面煤与瓦斯突出防治提供了借鉴。

There is a correlation between the main controlling factor of coal and gas outburst and the choice of sensitive index. Through the comprehensive analysis of coal and gas outburst characteristics over the years,the correlation between mining geology structure and gas content,parametric measurement of coal samples,we determine main controlling factors of coal and gas outburst in Liangbei Coal Mine. According to the correlation,we carry out post- conducted sensitive index investigation and verification in the front of the heading face on- site,which provides the reference for coal and gas outburst prevention and treatment for similar outburst mines.
