摘　　要：针对金城金矿东季矿区应用下向分层进路充填采矿法时，因海砂胶结充填料输送难、矿区需建多个充填站，而高水速凝胶结充填体后期强度低，不适用于下向充填采矿法等问题，开展了尾砂胶结充填新工艺的研究。In the application of downward drift slicing and backfilling in Dongji mining area of Xincheng Gold Mine,due to the nocessity of erecting several filling stations in mining area resulted from hard haulage of beach sand and also owing to the low strength of polyhydrite content of accelerating consolidated filling body in later stage,it is unsuitable for applying downward back fill method,thus the studies on consolidated fill with tailing are launched.
