Rather than a mix I think you want a three stage explosive. First stage is a small burst of fire dust at the core, detonates and expands rapidly to trigger the thicker layer of wind dust which provides physical force. Last up is a shell of earth dust which goes off and generates chunks of rock which are propelled by the expanding pressure wave from the wind.
