description The embodiments of the present invention provide a mine water inflow calculation method and device. The calculation method includes the following steps that: when a coal seam roof rock layer is cavedand fractured, the sum of the water release amount of a binary structure body and the amount of water infiltrating into a mine from the boundary flow cross-section of a groundwater water-bearing system is calculated during the gravitational water release period of the current caving and fracturing, and is adopted as mine water inflow, wherein the water release amount of the binary structure body is obtained according to the average flow rate of the elastic water release amount of the binary structure body during the gravitational water release period of the current caving and fracturing and the sum of the gravitational water release amount of each water-bearing layer; after the gravitational water release period of the current caving and fracturing, the amount of water infiltrating into the mine from the boundary
