After push back and release from tug; we were unable to move the aircraft with 1 engine. We called to have the ramp personnel come back out and check things out. Ops responded that they would call ramp. No one came out to aircraft. At this point; other aircraft were calling for push. We were blocking all operations. I called ground and confirmed the area behind was clear; started engine 2 and used both engines to get moving. During push back we felt the aircraft roll into a hole and then back out. During initial taxi; still using 1 engine; we rolled into this hole and became stuck.The Company might want to investigate the further. I checked my release and NOTAMs and didn't see any reference to this.
The reporter stated that his aircraft was pushed back and stopped on the taxiway common to both Concourses 'C' and 'D'; approximately abeam Gate D3. The reporter's main concern was his aircraft engine's exhaust blast at high power might cause injury or damage.
A large air carrier transport jet attempted to taxi on a single engine after pushback and engine start at MSY; but was unable to move because the aircraft's wheels were in a ramp depression.
