| 摘 要： | 逐步回归是一种可以有效地挑选重要因素剔除不重要因素,建立科学的符合实际的因变量自变量关系的数学方法。通过运用逐步回归分析方法研究大湾煤矿11煤层多次煤与瓦斯突出事故发生情况,得出了煤层埋深是影响煤与瓦斯突出危险性的关键因素,为合理配置安全投入,对主控因素进行针对性治理提供了科学依据。

| Abstract: | Stepwise regression is an effective selection of the important factors to eliminate unimportant factors, the establishment of scientifically consistent actual dependent variable argument to the relationship between the mathematical method. Through the use of stepwise regression analysis method to study Dawan Coal Mine 11 coal seams draw a seam depth key risk factors affecting the coal and gas outburst, a number of coal and gas outburst accident happened as the rational allocation of investment in safety, the main controlling factors provide a scientific basis for the targeted treatment. |
