Coal mine goaf exploration system based on spatio-temporal data fusion

The invention belongs to the technical field of geological exploration, and particularly discloses a coal mine goaf exploration system based on spatio-temporal data fusion, which comprises a data preparation module, the data preparation module is connected with a numerical inversion module, the numerical inversion module is connected with a fitness estimation module, the fitness estimation module is connected with an optimization iterative calculation module, and the optimization iterative calculation module is connected with a data processing module. And the optimization iterative calculation module is connected with a space-time fusion subsidence evaluation module. According to the method, the mining relation of historical mining of the goaf is accurately described by fusing the spatial-temporal characteristic parameters during historical mining of the coal mine goaf, so that the ground subsidence degree caused by secondary mining of the goaf under different geological conditions can be well described accor
