The invention provides a high-temperature-resistant emulsion explosive, and specifically provides a high-temperature-resistant emulsion explosive used at a geothermal high-temperature environment anda package, and double insurance is provided for high-temperature blasting operation. The explosive can be normally detonated for 10 cycles in a high-low temperature cold-hot cycle test (-40 DEG C to 80 DEG C), so that the safety and detonation stability of the emulsion explosive in a high-temperature operation environment are greatly improved; the high-temperature-resistant emulsion explosive provided by the invention is simple in formula; and a provided aerogel film sleeve is a continuous porous material composed of nano-scale silicon dioxide (SiO2) particles, has excellent properties such ashigh porosity, low density and low thermal conductivity, and can be used as a thermal insulation device to perform flame retardancy and thermal insulation on the geothermal high-temperature environment, thereby ensuring the s
