In order to visualize the geological distribution of coal seam and the occurrence of coal and rock mass in coal mining face, and enhance the expressiveness and utilization of geological data,a three-dimensional modeling scheme of Web-end coal seam is proposed. Based on the sampling data of 16402 coal mining face in a coal mine, the digital elevation model of coal seam surface was constructed by combining regular grid method and adaptive differential evolution Kriging spatial interpolation algorithm(UMDE-Kriging).After that, the three-dimensional model of coal seam in browser-side mining face was realized by using Three.js Technology and Catmull-Rom spline curve, and the dynamic display of coal quality index was realized.It is showed that the model constructed truly reflects the shape, occurrence and ore grade of coal seam in the working face, which provides a reliable basis for the comparative decision-making of production schemes.
