摘　　要：为了研究高瓦斯矿井工作面瓦斯赋存规律的影响因素,以文家坡煤矿4101工作面为背景对煤层厚度和煤层埋深等条件进行单因素和多因素的线性回归分析,得出与瓦斯含量相关程度最大的影响因素为煤层埋深,并得出与其的函数线性关系式。以煤层埋深作为其位置坐标瓦斯含量值拟合的基础,运用绘图软件绘制4101工作面瓦斯等值线图。分析发现,从工作面切眼到停采线的瓦斯含量逐渐降低,得出的煤层瓦斯赋存规律对4101工作面煤层瓦斯预抽以及工作面回采期间的风量分配、瓦斯防治具有指导意义。In order to study the influential factors on the gas occurrence law in the working face of high gas mine,the linear regression analysis of single factor and multiple factor was carried out on the coal seam thickness and buried depth and other conditions based on the background of 4101 working face of Wenjiapo Coal Mine,and the coal seam buried depth,which is the most influential factor related to the gas content,and the linear relation of its function,was obtained.Taking the buried depth of coal seam as the basis of fitting the gas content value of coordinates of other positions,the gas contour map of 4101 working face was drawn by drawing software,and the gas occurrence law of the first mining face was obtained.It has certain guiding significance for coal seam gas pre-extracting and air volume distribution and gas prevention during mining in 4101 working face.
