Fine grain tailing dam section consolidation degree generalization zoning method
A generalization zoning method for the section consolidation degree of a fine grain tailing dam is used for zoning the section of the fine grain tailing dam, a tailing pond is divided into a plurality of tailing layers according to the consolidation time of tailings, the same tailing layer is divided into a plurality of small areas according to the drainage distance, and the consolidation time and the drainage distance of the adjacent tailing layers are sequentially compared; and according to the consolidation time and the drainage distance, areas with similar consolidation degrees are determined, the small areas with similar consolidation degrees are divided into the same large area, and finally the tailings pond is divided into a plurality of large areas. Compared with the prior art, the method has the beneficial effects that the problem that fine-grain tailings are difficult to partition in a traditional mode is solved, the stability of the tailing dam depends on the shear strength of all parts of the section of the dam body, and the shear strength of the tailings depends on the consolidation degree of the tailings; according to the zoning method, the sections of the fine-grain tailings are zoned according to the consolidation degree of the tailings, and then stability analysis and safety evaluation of the fine-grain tailings pond are achieved.
一种细粒尾矿坝剖面固结度概化分区方法，用于对细粒尾矿坝剖面进行分区，将尾矿库按照尾矿的固结时间分为多个尾矿层，同一尾矿层按照排水距离分为多个小区域，依次对比相邻尾矿层的固结时间及排水距离，根据固结时间及排水距离确定固结度相近的区域，将固结度相近的小区域划分为同一个大区域，最终将尾矿库划分为多个大区域。与现有技术相比，该发明的有益之处在于：上述分区方法解决了细粒尾矿难以以传统方式进行分区的难题，尾矿坝的稳定性取决于坝体剖面各部位的抗剪强度，而尾矿的其抗剪强度取决于其固结程度，上述分区方法根据尾矿固结度对细粒尾矿剖面进行分区，进而实现对细粒尾矿库的稳定性分析和安全评价。
