In recent years, the coal industry has made considerable progress, coal production has continued to grow, production technology has gradually improved, coal mine safety production conditions have improved, and it has played an important role in national economic and social development. However, Chinas coal mine gas disaster is still very serious, especially the gas dynamic disaster represented by coal and gas outburst is a major disaster that often occurs in the mining process, which seriously threatens the safe production of coal mines, restricts the mining speed of mines, and affects the coal mines. Economic benefits. Therefore, research on the control factors of gas dynamic disasters is essential to ensure the safe production of coal mines. Based on the in-depth study and analysis of the mechanism of gas dynamic disasters at home and the geological influencing factors of gas dynamic disasters, combined with the actual fault structure development in the Luan mining area, the characteristics of the coal seam pore structure were tested through experimental analysis and theoretical discussion. Based on the experimental data, the influence of fault structure on the pore characteristics of coal seams is analyzed. The control effect of coal seam pore characteristics on gas dynamic disasters is analyzed indirectly. The adsorption-desorption experiment of coalbed high pressuregasiscarriedouttostudythefaultstructure.Theinfluenceofthe adsorption-desorption characteristics of coal seams on the coal seam adsorption-desorption characteristicsisanalyzed.Thecontroleffectofcoalseamadsorption-desorption characteristics on gas dynamic disasters is analyzed. Through the above test analysis, the control effects of different types of fault structures on the local accumulation of gas occurrence are studied. Finally, based on the research on the principle of control of gas dynamic disasters based on fault structure, the effective control of gas dynamic disasters is realized. Through the research on the control effect of fault dynamics on gas dynamic disasters, the relevant principles are applied to No.3 coal seam of Gaohe coal mine, Luan, Shanxi, combined with the actual production parameters, the effective analysis and verification of the gas dynamic disaster characteristics of No.3 coal seam of Gaohe coal mine, Luan, Shanxi are carried out, and the applicability and reliability of the relevant control principles are verified. 万方数据 III It provides new technical support for the prevention and control of coal mine gas disasters.
