The similar simulation experiment studying of pressure relief gas seepage law under the influence of mining
Using self-developed solid gas coupling similar simulation experimental platform,process of stress distribution of coal floor and discharging pressure gas seepage velocity with the change rule of working face advances by experiments and analysis from coal floor in the goaf abutment pressure distribution rule and influence in the area of goaf,determines the range which is the gas seepage velocity change the form of ”three zones” of the transverse direction along the top of goaf,summarizes the seepage rule of discharging pressure gas.Results for the spot gas extraction provides technical support.
