渗透率对采空区流场有重要影响,为了使采空区渗流场模拟更接近实际,总结了国内外关于采空区渗透率的分布模型,分析了采空区上覆岩层的垮落特征,并基于采动裂隙"O"形圈理论,研究了采空区孔隙率、渗透率的三维空间连续分布模型. 结果表明,该分布模型能够反映采空区渗透率三维分布特征,而且在采空区内部都是连续的,有利于采空区渗流场求解.

The permeability has a significant impact on the seepage field in gob. In order to make the simulation of the seepage field in the gob closer to the actual condition, the permeability distribution models both at home and abroad were summarized and the caving characteristics of the overlying strata in the gob were analyzed. Based on the O-shaped circle theory of the mining-induced fractures, study was made on the three-dimensional continuous distribution model of porosity and permeability in the gob. The results showed that the distribution model could reflect the three-dimensional distribution characteristics of permeability in the gob and it was continuous in the gob, so it was beneficial to the solution of seepage field in the gob.
