The invention provides a geophysical detection method and system based on muon momentum, and the method comprises the steps: placing a detector A in an object-free region, and placing a to-be-detected object and a detector B in a to-be-detected region; the muon multiple coulomb scattering angle theta MS of the to-be-detected area recorded by the detector B is obtained, and the muon multiple coulomb scattering angle theta MS0 of the object-free area recorded by the detector A is obtained; the muon momentum P of the to-be-detected area is calculated through the theta MS, and the muon momentum P0 of the object-free area is calculated through the theta MS0; obtaining a muon energy value Ec of the to-be-detected area through P calculation, and obtaining a muon energy value E0 of the object-free area through P0 calculation; an actual energy loss value Et is obtained through calculation of Ec and E0, the material opacity delta of the object to be detected is obtained through calculation of Et, and the material densi
