Analysis of the Regularity and Characteristics of Mine Pressure Manifestation in Coal Seam Fault Working Face
In order to explore and analyze the manifestation law and characteristics of the fault pressure in the working face,a study was conducted on the mining roadway of the 81308 working face in a certain mine.Numerical simulation methods were used to establish a numerical model to analyze the pressure law of the working face when it is close to the goaf,and an optimization plan for passing through the fault was proposed to ensure the safety of coal seam mining.Through on-site monitoring,the results show that the measured subsidence of the roof is 65.8 mm,the maximum slip of the fault is 75 mm,and the economic benefits are significant,achieving safe and efficient mining of the working face.
