Gas occurrence law of first working face in Wenjiapo Coal Mine
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.
