全尾砂密度及孔隙率物理性质测定试验研究

Experiment of Physical Properties of Density and Porosity for full Tailings

尾砂含水率、密度、松散密度及孔隙率等是全尾砂基础的物理性质参数,也是矿山进行充填系统技术升级和系统改造的重要技术参数,本文中对技术人员采用烘干法,测得全尾砂试样含水率和利用容量瓶测定全尾砂的固体密度(比重),以及在温度为20℃时,全尾砂的固体密度测定的做法进行了详解,对需要开展此类科研工作的矿山企业提供了实际的借鉴意义。

Moisture content,density,loose density and porosity,as the important technical parameters for technical upgrading and system transformation,are the basic physical property parameters of full tailings.This paper adopts drying method to measure moisture content and solid density of the full tailings.Additionally,the detailed measuring method of solid density of full tailings at 20℃is introduced,which can be reference for the similar mines.
