摘　　要：为解决金川Ⅲ矿区矿体埋藏浅,充填倍线高,细砂管道自流输送困难等问题.根据西二采场的充填倍线,并考虑到弯管、岔道负压区局部阻力,确定了加压输送能力和出口泵压力.在此基础上,确定了液压系统额定工作压力和配套充填管径,选择了配套泥浆泵和电动机.然后,在地表开展了料浆浓度泵送充填试验.结果表明,加压泵性能完全满足料浆输送要求.最后在井下开展泵送充填工业试验,结果表明,泵压输送充填浆体在进路中流动良好,料浆接顶满足充填采矿要求,充填体3d、7d和28d强度均达到设计要求.该充填系统已在金川西二采区实现了工业化应用.The resources development for the lean ore at Ⅲ mining area in Jinchuan Mine is the strategic decision in order to achieve the sustainable development for Jinchuan Group Ltd. It is difficult that the slurry fme sand pipeline transport is used gravity, because the depth of ore bodies buried is shallower and filling times line is higher. The filling system by pumping pressure was designed and industrial test was implemented. Based on the filling times line, the pressure transmission capacity and export pump pressure were determined considering the local resistance of bent pipe and turn negative pressure zone. On this basis the nominal working pressure of the hydraulic system and supporting the filling pipe diameter were given and the form a complete set of mud pump and motor were selected. Then the pumping filling test in the surface was carded out. The results indicate that the performance of the pressure pump meet the requirements of slurry transportation. In the end, the pumping filling industrial test in underground was implemented. The resultes show that the liquidity of the slurry in access is better, slurry by top meet design requirements and the strength of filling body of 3d, 7d, 28d all reaches design requirements. The filling system had been used at the second west mining area in Longshou Jinchuan Nickel Mine.
