摘　　要：通过对以往砂矿开采设计及生产实验资料的分析,论述了主要水运参数、断面形状、材料选择的原理及适用性,并进行经济分析。总结砂矿开采冲矿沟自流水力运输的基本水力参数,以改善自流运输条件,杜绝冲矿沟淤积堵塞事故,保证生产均衡。On basis of analysis on past placer mining design and production experiment data,the main hydrotransport parameters,sectional form,theory and applicability of material selection were discussed and the economic analysis was carried through. The basic hydraulic parameters of ore ditch artesian hydro-transport of placer mining were summarized so as to improve the artesian transportation conditions,avoid the accident of ore ditch sedimentation jam and guarantee production smoothly.
