【摘要】：全尾砂非胶结充填是矿山经济高效的充填方式,如何实现采场快速有效地脱水是非胶结充填中最难解决的问题。研究压风强化脱水机理,根据相似原理建立采场压风强化脱水实验模型。通过实验探索压风强化脱水工艺参数,并得出压风强化脱水管参数,为矿山全尾砂非胶结充填压风强化脱水工艺提供理论指导。利用流体力学数值模拟软件FLUENT建立压风强化脱水数值分析模型,通过压风强化脱水数值模拟分析,揭示全尾砂非胶结充填压风强化脱水过程中气、水运移规律及强化脱水效果的影响因素,进一步验证全尾砂非胶结充填压风强化脱水的可行性。
[Abstract]:Non-cemented filling with complete tailings is an economical and efficient filling method in mines. How to dewatering stope quickly and effectively is the most difficult problem in non-cemented filling. This paper studies the mechanism of pressurized wind enhanced dehydration and establishes an experimental model of stope pressure wind enhanced dehydration according to the similarity principle. The parameters of pressurized wind strengthened dehydration process are explored through experiments, and the parameters of pressurized wind strengthened dehydration pipe are obtained, which provides theoretical guidance for the whole tailings non-cemented filling pressurized wind strengthened dehydration process. The numerical analysis model of pressurized wind intensified dehydration was established by using fluid dynamics numerical simulation software fluent. Through the numerical simulation analysis of pressurized wind enhanced dehydration, it was revealed that the gas in the process of full tailings filling was filled with compressed wind during the dehydration process. The law of water migration and the factors influencing the effect of intensified dehydration further verify the feasibility of full tailings non-cemented filling with pressurized wind intensified dehydration.
