And for experimental method, the value of optimum frequency is derived from laboratory research. Here is the example of using the experimental method. Given six samples of coal with the code S, A4, L, 3, A6, and I. The vibro seismic method is applied with various frequency’s value in each samples. And the value of permeability is measured using Hasler permeameter tool in each frequency. Tables below show the effect of vibro seismic to the change of permeability and porosity.
