Method for evaluating water filling state of goaf

The invention relates to a goaf water filling state evaluation method, belongs to the technical field of mining safety evaluation, and discloses a goaf water filling state evaluation method based on numerical simulation and an incremental subset SVR technology. According to the method, the water filling degree is defined as an important index of the water filling degree of the goaf, a stope numerical model containing the water-filled goaf is established in the forms of remote sensing interpretation, geological exploration and geophysical prospecting, indoor testing and field monitoring, and a prior database composed of the water filling degree, the water inflow and hydrological parameters is established through numerical simulation. Dynamic and efficient goaf water filling state evaluation is achieved through the incremental subset SVR technology, and reference is provided for safety production of mine enterprises. The goaf water filling degree evaluation method has the advantages that the problem of goaf wat
