  In this paper, we prove the boundedness of foliated surfaces
$(X,\mathscr{F})$ which are minimal partial du Val resolutions of canonical
models $(X_c,\mathscr{F}_c)$ of general type. For applications, we show the
boundedness of non-cusp singularities on canonical models of foliated surfaces
of general type and the effective generation on the complement of the cusp
singularities.
