The invention relates to the technical field of explosion, in particular to a carbon dioxide heating powder composition, at least comprising organic acid, metal powder, an oxidant, an ammonium compound and plant ash. The carbon dioxide heating powder composition has the advantages of high explosion speed, zero noise, zero dust and the like; the requirement for quick construction can be met, and explosion efficiency can be improved; the carbon dioxide heating powder composition is non-inflammable, non-explosive and nontoxic and is very safe to transport, store and use, and the defects of detonators and explosives are overcome; there is no toxic and high-temperature matters produced and zero gas explosion caused in the explosion process; small blasting vibration is caused, and the composition is simple to make and low in cost; a blasting method is simple to use and has no special requirement on construction operations, zero flame and low temperature are caused in blasting, and therefore, the advantages of the composition are achieved.
