Study on Gas Seepage Law in Gas Conductive Fracture Zone of Gob

To master the gas seepage law in goaf gas conductive fractured zone of overlying strata, by physical simulation and theoretical analysis, the lateral partition for the gas conductive fracture zone is carried out and the gas seepage law in the lateral partition of the gas conductive fracture zone is studied. The results show that according to the stress distribution characteristics of mining, goaf gas conductive fractured zone of overlying strata can be divided into lateral fissure zone, gas conductive fissure "O" shape, compaction area in lateral; the gas in lateral fissure zone and compaction area flow is Darcy percolation, and the gas in gas conductive fissure "O" shape flow is turbulence.
