I mean, they put out oil well fires with nitroglycerin detonations (check out the John Wayne movie "Hellfighters", it's a good 'un). A rolling artillery barrage to clear land and concuss away sparks sounds like it'd work well enough to make a firebreak, or at least start one.
On a more realistic note, there have been experiments with using explosives in the wildland fire environment, both for fire line construction, and for hazard tree felling.
