The invention relates to a coal seam three-dimensional model construction method based on layer-crossing drilling construction data, and belongs to the field of coal mine geology. The method comprises the following steps: acquiring coal mine crossing drilling construction data; according to drilling construction data, a spatial position algorithm is applied, and spatial coordinates of a coal seeing point and a coal outlet point of each drill hole are calculated; performing three-dimensional interpolation, resampling, point thinning and three-dimensional interpolation again on the space coordinate data of all the coal seeing points and the coal discharging points to obtain curved surface diagrams of a coal seam top plate and a coal seam bottom plate; and sewing the periphery of the coal seam roof and floor curved surface drawing to form a three-dimensional model of the coal seam. According to the method, the coal seam high-precision three-dimensional model can be generated by using the coal seam crossing drill
