Analysis of main control factors of gas occurrence in the main coal seam of Hancheng Xiangshan Coal Mine
摘要
Abstract
The current geological conditions of gas in the 3# and 5# coal seams of Xiangshan Mine are complex,and the oc-currence of gas is unclear,which brings great difficulties to the engineering background of gas prevention and control in new working faces and new mining areas.We conduct a study on the main controlling factors of gas occurrence in coal seams 3#and 5#.Through data regression analysis,it is found that the gas content in coal seams 3# and 5# is approximately linearly positively correlated with coal seam thickness and burial depth.The thickness of coal seams 3# and 5# accounts for about 10％and 16％of the reasons for gas content changes,while the burial depth of coal seams 3# and 5# accounts for about 45％and 20％of the reasons for gas content changes;There is an approximate linear negative correlation between the thick-ness of sandy mudstone and the roof.The thickness of sandy mudstone within 10 meters of the roof of coal seams 3# and 5#accounts for 42％of the reason for the change in gas content,indicating a significant correlation.Through grey correlation a-nalysis,it was found that the correlation degrees between the geological structures of the 3# and 5# coal seams were 0.689 and 0.761,respectively,and the correlation degrees of burial depth were 0.682 and 0.762,respectively.Geological struc-tures and burial depth are the main controlling factors for gas occurrence in the 3# and 5# coal seams.关键词
