My unofficial and slightly off the cuff interpretation leads me to think that no, the miner would survive. Why: The first step of combat order is move off the map, eliminate decoys, reveal units, attacker conducts minesweeping, mines detonate, form battle lines. Then, the attacker fires. This indicates to me that the scout would die before firing. Additionally, 5.4 states that noncombat units are destroyed if targeted by a firing ship so if the mines eliminate the firing ship the miner survives.
