How do I extract coefficients from an "equation?"

This is my equation:

      eqn15 =(2519*Ncz + 2736)*z + (86860*Nck)*kh == (20*Nkz*(4439*Nck + 48))*z + (20*Nkk*(4439*Nck + 48))*kh

I want to extract the coefficients off the two of the symbolic variable kh and z (all letters in the equation are symbolic) to create two separate equations of the form: (86860*Nck)=(20*Nkk*(4439*Nck + 48)), but I have not found any method for doing this. Is there a simple way to do this?

and before that you would probably want to use children() to separate the two parts of the "=="
