我国在砂矿床水力机械化开采方面,集累有丰富的实践经验。而明沟水运矿石是水力开采的重要生产环节,其特点是:生产可靠,运输能力大,设备简单,维修量小,动力消耗少,生产成本低,是最经济的运输方式之一。因此,研究发展水力运矿技术有重要的实践意义。本文仅就明沟水力运矿的试验研究方法,做一初步探讨。(一)基本特性的确定明沟运矿不同于明渠泥砂输送的研究,它是研究运输块度、形状、比重都不相同的固体松散物料,
China has accumulated rich practical experience in the mechanization and mining of sand deposits. The clear ditch water transport ore mining is an important production link, which is characterized by: reliable production, transport capacity, simple equipment, small maintenance, less power consumption, low production costs, is one of the most economical mode of transport. Therefore, research and development of hydraulic transport technology has important practical significance. In this paper, only on the experimental research method of the Ming ditch hydraulic transport, to do a preliminary discussion. (A) to determine the basic characteristics Minggouyun different from open channel silt transport research, it is to study the lumps, shape, the proportion of solid loose materials are not the same,
