The invention provides a mine stratum water disaster detection and monitoring method, device and equipment and a storage medium, and the method comprises the steps: obtaining an electromagnetic field signal detected by an electromagnetic receiver which is located on a preset receiving working surface and used for receiving an electromagnetic field signal emitted by an electromagnetic emission source, the electromagnetic emission source is located on a preset emission working surface; based on a Gaussian Newton iteration method, inversion processing is carried out on the obtained electromagnetic field signals to obtain resistivity distribution of stratums to be detected, and the stratums to be detected are stratums corresponding to the transmitting working face and the receiving working face; and determining the water disaster distribution of the to-be-detected stratum based on the conversion relation between the resistivity and the water saturation and the resistivity distribution of the to-be-detected stratu
