There's some fairly impressive terrain around Shiraz.
Indeed, but if you look at the airport location, it sits on a dry lakebed with zero obstacles for 15-20 kilometres in either runway direction, plenty of room for low altitude maneouvreing.
In any case, several airlines operate 73' s into/out of Shiraz, so the field must meet one engine out takeoff performance requirements (to my knowledge without any limitations), performance on a missed approach can only be better.
