The irregular shape of mineral particles directly affects the angle of repose, bulk density and flow-properties, and the interaction behaviour between the particles and a contact surface. This paper presents a dataset of spatial data and shape parameters collected from 37 gangue particles and 135 anthracite coal particles, which come from the Shangzhuang Coal Mine. The particle surface models were obtained by a Wiiboox white light raster 3D scanner and Reeyee software. To obtain the scanning surface, each particle was scanned 8 times in different axial rotation directions. The final scanning model was obtained by stacking two scanning surfaces, and the shape parameters, such as length ratio, flatness ratio, and Zingg index, were obtained. This dataset is particularly useful for researchers and engineers who want to investigate the shape of coal and gangue particles or who want to test or benchmark measurement methods concerning the three-dimensional morphology of particles.
矿物颗粒的不规则形状会直接影响休止角、堆密度和流动特性，以及颗粒与接触面之间的相互作用行为。本文提供了一个数据集，其中包含了从尚庄煤矿采集的 37 个矸石颗粒和 135 个无烟煤颗粒的空间数据和形状参数。颗粒表面模型是通过 Wiiboox 白光光栅 3D 扫描仪和 Reeyee 软件获得的。为了获取扫描表面，每个颗粒在不同的轴向旋转方向上扫描了 8 次。最终的扫描模型是通过堆叠两个扫描表面获得的，然后可以得到长度比、扁平度比和 Zingg 指数等形状参数。这个数据集对于希望研究煤和矸石颗粒形状的研究人员和工程师，或者希望测试或基准化有关颗粒三维形态的测量方法的人员非常有用。
