  Existence of global weak solutions to the continuous Oort-Hulst-Safronov
(OHS) coagulation equation is investigated for coagulation kernels capturing a
singularity near zero and growing linearly at infinity. The proof mainly relies
on a relation, between classical Smoluchowski coagulation equation (SCE) and
OHS coagulation equation, which is introduced in [16] as generalized
coagulation equation. Moreover, all weak solutions formulated in a suitable
sense are demonstrated to be mass-conserving. We obtain here a similar result
for OHS coagulation equation as the one in [6] for SCE.
