Method for evaluating permeability and strength of bonding of high polymer material and coal-rock mass

The invention discloses a method for evaluating the permeability and strength of bonding of a high polymer material and a coal and rock mass. The method comprises the following steps: S1, determiningthe permeability k1 of the coal and rock mass; S2, determining the bonding permeability k2 of the high polymer material and the coal and rock mass; S3, if the k1 is smaller than the k2, determining that the bonding permeability of the high polymer material and the coal-rock mass does not meet the standard; otherwise, determining that the bonding permeability of the high polymer material and the coal-rock mass meets the standard, and entering the S4; S4, determining the shear strength Gamma 1 of the coal and rock mass; S5, determining the bonding strength Gamma 2 of the high polymer material and the coal and rock mass; S6, if the Gamma 1 is greater than the Gamma 2, determining that the bonding strength of the high polymer material and the coal-rock mass does not meet the standard; otherwise, determining that the b
