This invention discloses a low-temperature carbon dioxide high-expansion foam dust suppression system and method for ore pass unloading. The dust suppression system includes a first high-expansion foam generator and a second high-expansion foam generator at the ore pass unloading port and ore bin, respectively. A foaming dust suppressant is mixed with inert carbon dioxide gas and a sulfide ore inhibitor to create foam with both dust suppression and ore spontaneous combustion inhibition properties.

Therefore, this invention's low-temperature carbon dioxide high-expansion foam dust suppression system achieves synergistic prevention and control of dust and ore spontaneous combustion within the ore pass.
