摘　　要：为了直观展现采煤工作面煤层地质分布和煤岩体空间赋存状况,增强地质数据的表现力和利用率,提出一种Web端煤层三维建模方案。该方案以某煤矿16402采煤工作面部分采样数据为基础,结合规则格网法和自适应差分进化Kriging空间插值算法构建煤层表面的数字高程模型;之后借助Three.js技术和Catmull-Rom样条曲线实现浏览器端采煤工作面煤层三维可视化模型,并实现煤质指标的动态展示。研究表明,所建模型真实地反映了工作面煤层的形态、产状和矿石品位,为生产方案对比决策提供了可靠依据。To visualize the geological distribution of coal seam and the occurrence of coal and rock mass in coal mining faces,and enhance the expressiveness and utilization of geological data,a three-dimensional modeling scheme of Web-based terminal was proposed.Using 16402 sampling data,a digital elevation model of coal seam surface was constructed by combining regular grid method and adaptive differential evolution Kriging spatial interpolation algorithm.After that,a three-dimensional model of coal seam in browser-side mining face was realized by using the Three.js Technology and Catmull-Rom spline,and the dynamic display of coal quality index was realized.It was shown that the new model truly reflected the shape,occurrence,and ore grade of coal seam in the working face,and provided a reliable basis for the comparative decision-making of production schemes.
