尾矿库溃坝淹没范围的定量计算方法研究
Research on Quantitative Calculating Method for Tailing Ponds Submerged Area in Metal and Nonmetal Mines
【摘要】 为降低人造高势能饱和体-尾矿库在金属非金属矿山安全生产中的危险,提高尾矿库工程溃决的预报预测水平,以溃坝洪水与泥浆的动力学过程作为研究重点,以溃坝洪水运动为主线,综合运用水文学、水动力学等运动理论和有限差分数值计算方法,建立描述尾矿库溃决泥浆运动的数值模型,研究得到尾矿库溃坝淹没范围的定量评估方法。最后进行实际工程预测,计算表明该模型和计算方法可为尾矿库溃坝风险等级的划分提供依据。
【Abstract】 In order to reduce the artificial stone flow of tailing ponds with high potential energy in safe production of metal and nonmetal mines,and to improve the disaster forecast level,this paper,taking the failing and mud hydrodynamic procedure as the research focus and the flooding of failing as the main thread,comprehensively employs hydrology,hydrodynamic theory and finite difference method to build a numerical model of mud hydrodynamic procedure,and then proposes a quantitative assessment method for tailing ponds submerged area.Typical project example demonstrates that the model and the calculation method are applicable,and that the calculating method can also provide basis for the risk grading of tailing ponds.
