A method for extracting bitumen from a subterranean oil sand deposit comprising: a) removing an overburden from a subterranean deposit; b) blasting the subterranean deposit to fragment the subterranean deposit thereby forming a blasted deposit, the blasted deposit being operable to permit a flood volume of fluid to admix with the blasted deposit, to ablate and then release the heavy oil off an inert material so that the heavy oil floats on the flood volume of fluid forming a froth composed of the flood volume and the released bitumen up through and then above the blasted deposit; c) flooding the blasted deposit using the fluid , thereby forming a flooded deposit; d) recovering the heavy oil with the flood volume of fluid in the flooded deposit; and e)removing the fluid from the flooded deposit, thereby forming a treated deposit, the treated deposit being compacted by removing a fluid from the flooded deposit so that the treated deposit is not sufficiently permeable to accept a second flood volume of flu id from an adjacent blasted deposit, is provided.
