The method comprises the following specific steps: arranging GNSS continuous observation points at key positions in a mining influence range; unifying the elevation system of the measurement area based on the position information of the GNSS continuous observation points; and by taking the plane position and elevation of the key position measuring point as a reference, carrying out comprehensive observation and daily observation through a local short-distance lead and a level line to obtain a surface movement deformation value and a surface subsidence prediction parameter of the mining subsidence area, so that the measurement of the surface subsidence of the mining area is realized. The repeated connection measurement process is omitted, so that the observation efficiency and precision are improved.
