摘要:

充填料浆的流变性是影响管道输送能力和充填能力的重要因素。以试验为主,在分析尾矿物理化学性质的基础上,对充填料浆的塌落度、扩展度,以及影响流变性的料浆浓度、充填倍线、充填管径等因素开展试验研究,以确定矿山实际生产的料浆浓度。研究结果表明:水泥的添加对料浆塌落度有明显的影响,将料浆流动性突变的临界料浆浓度由72 %增加至74 %;料浆浓度对流变性影响显著,推荐充填料浆浓度范围为70 %~72 %;在实际生产中,要根据矿山实际确定充填管道管径和充填料浆流速。该试验研究明确了充填料浆的流变特性,对矿山实现安全高效充填采矿意义重大,同时,也为类似矿山提供参考借鉴。

Abstract:

The rheological behavior of filling slurry is an important factor affecting pipeline transport capacity and filling capacity.On the basis of the analysis of the physical and chemical properties of tailings,this paper carried out experimental study on the slump degree,the expansion degree of the filling slurry,and factors that influence rheological behavior including the slurry concentration,the filling doubling line and the pipe diameter,to determine the slurry concentration in the actual production of the mine.The results show that the cement addition has obvious influence on slurry slump,increasing the critical slurry concentration for mobility from 72 % to 74 %; slurry concentration has significant influence on rheological properties,and the recommended concentration ranges from 70 % to 72 %; in production,the diameter of filling pipe and the velocity of filling slurry should be determined according to the actual situation of the mine.The experimental study has made clear the rheological properties of filling slurry,which is of great significance for the mine to achieve safe and efficient filling mining,and also provides reference for other similar mines.
