一、概述散体物料的管路水力输送,近期发展较快,应用较广。在采矿工业中,主要是用于向尾矿坝输送尾砂,以及输送精矿和充填法中向井下输送充填料等。在管路输送中,浓度是一个主要参数之一。它不仅与水力坡度、管路磨损等有关,而且在胶结充填中,还严重影响充填体强度,此时我们都要设法提高浓度来满足地下采矿的要求。但在一般向尾矿坝泵送尾砂时,无强度等因素的要求。此时输送浓度愈
First, an overview of bulk materials pipeline hydraulic transport, the recent rapid development, wide application. In the mining industry, it is mainly used to transport tailings to the tailings dam, as well as to transport concentrate and fill materials to the well during filling. Concentration is one of the main parameters in pipeline transportation. It is not only related to the hydraulic gradient, pipeline wear and so on, but also in the cementation filling, but also seriously affect the strength of the filling, at this time we must try to increase the concentration to meet the requirements of underground mining. However, in the general tailings dam pumping tailings, no strength and other factors. At this point the delivery of the more concentration
