Lead-zinc mine filling material and preparation method thereof
The invention discloses a lead-zinc mine filling material and a preparation method thereof. Solid components of the lead-zinc mine filling material comprise lead-zinc mine graded tailings, a gelatinizing agent and a water reducing agent, wherein the gelatinizing agent comprises the following components: casting tailings, mineral powder, cement and an exciting agent. The lead-zinc mine filling material is prepared from the casting tailings and the mineral powder, the performance of the lead-zinc mine filling material can achieve the effect of a pure cement cementing material, and the lead-zincmine filling material is good in liquidity, easy to convey, small in abrasion to a pipeline and beneficial to protection of the pipeline. By preparing the lead-zinc mine filling material, accumulatedcasting tailings can be utilized on a large scale, land is saved, and the environment is protected.
本发明公开了一种铅锌矿山充填材料及其制备方法。这种铅锌矿山充填材料的固体组分包括铅锌矿分级尾砂、胶凝剂和减水剂；其中，胶凝剂包括如下组分：铸余尾渣、矿粉、水泥和激发剂。本发明采用铸余尾渣和矿粉制成一种铅锌矿山充填材料，其性能可以达到纯水泥胶凝材料的效果，而且这种铅锌矿山充填材料流动性好，易于输送，对管道的磨损小，有利于对管道的保护。制备本发明的铅锌矿山充填材料可以大规模利用堆积的铸余尾渣，节约用地，保护环境。
