煤体结构的变化直接影响矿井瓦斯的赋存与运移规律,从而影响矿井瓦斯灾害的形式和灾害后果的严重程度.采用压汞法研究了韩城矿区煤体姑构,并结合三轴渗透仪测试了煤层瓦斯渗透率及瓦斯吸附实验结果,研究了煤体结构对韩城矿区瓦斯危险性和灾害形式的影响,得出韩城矿区北区和南区3#煤层的差异及北区3#与11#两个不同煤层结构不同,导致煤层瓦斯渗透率、瓦斯吸附能力不同,因而瓦斯涌出规律、瓦斯灾害形式不同,为该矿区矿井瓦斯灾害的防治提供理论依据.表7,参8.
The change of coal structure directly affects the occurrence and migration of gas in coal mines, thus affecting the form of mine gas disasters and the severity of disaster consequences. The mercury arsenic in Hancheng mining area was studied by mercury penetration method. The gas permeability and gas adsorption experiment results of coal seam were tested with triaxial permeameter. The influence of coal structure on gas hazard and disaster in Hancheng mining area was studied. The difference between 3 # coal seam in North and South of Hancheng mining area and the difference in structure of 3 # and 11 # coal seam in North area lead to different gas permeability and gas adsorption capacity of coal seam, so gas emission law and gas disaster form Different, to provide a theoretical basis for the prevention and treatment of mine gas disasters in the mine area.
