摘要
根据达西定律 ,建立了风化矿体渗流的数值模型 ,并采用有限元方法求解。 1 8个矿体渗流计算模型分别考虑了不同注入形式、注入压力、矿岩渗透性、贮水系数对浸出的影响。通过计算分析 ,确定了原地浸出的钻孔布置参数、布液强度、作业制度及可能的渗漏情况。
According to Darcy law, the numerical model for leaching solution seepage in an efflorescent orebody is established. This model is solved by finite element method. The effects of different injection ways, injection pressure, permeability of ore and rock, water storage factors on leaching are considered in 18 models of calculating penetrating flow of leaching liquid through the orebody. Based on the calculation and analysis, drillhole pattern parameters, injection intensity, operation system and possible leakage are determined for in situ leaching.
