By considering the heterojunction made up of massive 8-Pmmn borophene, we present concentrations on its quantum transmission properties, with our purpose to the clarification of the valley polarization of propagation electrons. It is shown that when the Dirac mass is taken into account, valley splitting can be enhanced in the case of appropriate incident angles of electrons. After scattering at the interface of the heterojunction, electrons in the respective valleys will propagate in different directions, and the valley splitting still exists for the case of large junction angle. All these results are sensitive to the change of Dirac mass and incident energy. In view of these facts, one can ascertain that the heterojunctions based on massive 8-Pmmn borophene are promising candidates for realizing the valley polarization induced by the valley splitting of the propagation electrons.
