Help with mine explosion

[Rocknar]

Hi i am creating a new playable race, where i use haunted gold mine, but not for mining. My building has negative hp regen so it will be destroyed after time. BUT i need to destroy the golden mine in that moment too. I created a trigger but without result
It should work like this:
When haunted mine dies it explodes because of goblin mine ability and then golden mine in range should explode because of trigger.
Sry for bad quality of screenshot i am working and i have no connection here.

I found out that problem is that gold mine doesn't exist when haunted gold mine is up. I need to delay this trigger somehow Also goblon mine ability is problem too
