Ship Destroyed!

I lost a exhumer class mining barge today. This is THE ship I use for corp mining. I was looking for better ore and I couldn't find any. So I tried going to a low sec area, which also didn't have any. As I was trying to leave, I see a battleship in the rear view sensors. I knew from the start that this ship was trouble. However, there was nothing I could have done to prevent it. So the enemy battleship attacked me and I lost my ship.
