Narrative:
On final approach to dtw with flaps 15 degrees, we extended the landing gear. There were no gear indications (red or green). We executed a go around and coordinated with tower and approach control to an area where we could investigate our problem further. After referencing our aircraft manual emergency section and talking to maintenance control through our dispatch we checked the lng gear warning circuit breaker. It was popped and would not reset. We had, according to maintenance control, lost our automatic ground spoilers as well as gear indications. We performed a visual inspection of the main and nose gear as directed by our aircraft manual. All were safe. I declared an emergency with dtw approach and tower, with emergency equipment. The approach and landing were normal (ground spoilers were manually deployed). After I cleared the runway I terminated the emergency.
