摘　　要：由于煤矿瓦斯涌出量会受较多因素的影响,为了精准掌握瓦斯涌出量与各影响因素的联系,以双变量分析法为基础对瓦斯涌出量与各影响因素间的关系进行了分析,用留一交叉法对其进行验证。研究结果表明:瓦斯涌出量与日产量、回采速度、推进速度、原有瓦斯含量、煤层埋深、煤层厚度表现为正相关关系,与邻近层间距、大气压以及回采率表现为负相关关系。Due to the influence of many factors on the amount of gas emission from coal mines,in order to accurately grasp the relationship between gas emission quantity and various influencing factors,the bivariate analysis method is used as the basis to analyze the relationship between gas emission quantity and various influencing factors,and the leaving a crossover method is used to verify it.The research results indicate that there is a positive correlation between gas emission quantity and daily production,mining speed,advancing speed,original gas content,coal seam burial depth,and coal seam thickness,there is a negative correlation with the distance between adjacent layers,atmospheric pressure,and recovery rate.
