煤矿通常会突然将瓦斯与煤炭一起排出到矿井巷道中。瓦斯的主要成分是甲烷，因此所谓的煤与瓦斯突出是影响地下煤矿安全和生产的重大危险。有几个参数会影响这种爆发危险。在这项研究中，采用结构方程模型（SEM）这一统计方法来确定影响土耳其地下煤矿煤与瓦斯突出的参数之间的关系，并分析它们之间的多重相互作用。该模型包括主要因素（开采深度、煤层瓦斯含量和含水率）和影响因素（煤层厚度、煤层倾斜度和距断层距离）。结果表明，开采深度是主要因素中最有效的因素，而距断层的距离是对突出影响最大的因素。
Coal mines have sudden, usually unexpected expulsions of gas in conjunction with coal into the mine workings. The gas is mainly consisted of methane making this so-called coal and gas outburst a major hazard affecting the safety and productivity of an underground coal mine. Several parameters affect this outburst hazard. In this study, a statistical method namely structural equation modeling (SEM) was applied to identify the relationships between the parameters affecting the coal and gas outbursts for an underground coal mine in Turkey and to analyze multiple interactions between them. The model includes main factors (mining depth, coal seam gas content and moisture content) and contributor factors (seam thickness, seam inclination and distance from fault). The results indicate that mining depth is the most efficient factor in main factors and distance from fault is the most significant contributor to outburst.
