针对图拉尔根铜镍矿全尾砂、戈壁砂、全尾砂-戈壁砂混合料开展了一系列的试验研究,包括:基本物理化学性质测定,塌落度试验,环管试验,配合比试验,沉降泌水性能测定等试验研究,以寻求技术上合理、经济上划算的充填骨料。结果表面,全尾砂作为充填骨料适用于大部分充填体强度要求不高的矿山,其工艺简单,成本较低,综合效益较好。 A series of experimental studies have been carried out on the Tulaergan Cu-Ni tailings, Gobi sand and Tailing sand-Gobi sand mixture, including: basic physical and chemical properties, slump test, loop test, mixing ratio Test, sedimentation, bleeding performance test and other experimental studies to seek technically reasonable and cost-effective filling aggregate. As a result, the whole tailings, as the filling aggregate, is suitable for the mines with less requirements on the strength of the filling bodies. The process is simple, the cost is low, and the comprehensive benefits are good.
