This paper presents a dataset of spatial data, angles of repose and bulk densities collected from 108 bulk material heaps. The investigated materials were lignite, wood chips, limestone, blast furnace coke, fresh and dried corn grains, milk powder as well as bituminous coal. Sample sizes range from 16 liters to approximately 220 liters, and each measurement was repeated four times to allow for variance assessment. This dataset is particularly useful for researchers and engineers, who want to investigate the shape of bulk solid heaps, or who want to test or benchmark measurement methods concerning heaps of granular matter, such as the angle of repose.
本文提供了一个包含 108 个散装物料堆采集的空间数据、安息角和堆密度的数据集。研究的材料包括褐煤、木屑、石灰石、高炉焦炭、新鲜和干燥的玉米粒、奶粉以及烟煤。样本量从 16 升到大约 220 升不等，每个测量值重复四次，以评估方差。该数据集对于希望研究散装固体堆形状的研究人员和工程师特别有用，或者希望测试或基准测试与颗粒物质堆有关的测量方法，例如安息角。
