In this paper, the flow characters and resistance law are experimentally studied by three kinds of rock block media composed of triangular, parallelogrammic and rectangular unit blocks in laboratory. By a newly designed apparatus, the flow rate measurement and flow path observation are carried out with the porosity range of 2.62%〜16.21% for each medium. Experimental results are examined by the dimension analysis, and the permeability formula is proposed.
