单漏斗放矿柔性隔离层界面形态演化规律

Evolution law of interface morphology of flexible isolation layer under ore drawing from single funnel

采用Origin软件对隔离层界面形态演化观测数据进行拟合,并对高斯模型参数进行理论分析和统计分析,构建隔离层界面剖面整体动态函数表达式;将实测隔离层界面形态曲线与动态函数式进行比较,在力学分析基础上,推导底部类似抛物线形状的函数表达式,解出函数分界点坐标。两项函数式共同构成完整的隔离层界面形态数学模型。研究成果为柔性隔离层作用下散体介质流理论体系的系统构建打下坚实基础。

The observation data of interfacial morphological evolution of the isolation layer were fitted by Origin software, and the parameters of Gauss model were analyzed theoretically and statistically, and the dynamic function expression of the whole interfacial profile of isolation layer was established. Then, actual measured curves of isolation layer and dynamic function expression were compared, and the function expression of bottom shape which is similarly a parabola was derived, and the function boundary point coordinates were solved on the basis of mechanical analysis. The mathematical model of interfacial morphology of whole isolation layer was constituted by these two function expressions. Research results could be regarded as a solid foundation for the construction of the loose medium flow field theoretical system with flexible isolation layer.
