为了能应用地球物理测井参数来确定地浸矿山开采的含矿含水层的渗透系数,根据地浸矿山砂泥岩剖面中岩石的渗透系数主要与岩石的含泥量有关,以及地球物理测井参数自然电位的大小和电阻率高低已主要取决于岩石的泥质含量,利用室内岩石渗透系数与含泥量分析数据、地球物理测井自然电位和电阻率曲线原始资料,确定了渗透系数与自然电位和电阻率之间存在的相关关系,从而运用它们之间的相关曲线计算出钻孔含矿含水层中开采层位的渗透系数和钻孔抽液能力比流量。
In order to use geophysical well logging parameters to determine the permeability coefficient of the ore-bearing aquifer in dip leaching mining, the permeability coefficient of rock in the leached sandstone-shale profile is mainly related to the clay content of the rock, and the geophysical log parameters The size of the potential and the resistivity level have been mainly determined by the shale content of the rock. Based on the data of the rock permeability and clay content, the original data of the natural potential and resistivity of the geophysical logging, the relationship between the permeability coefficient and the natural potential and The relationship between the resistivity of the correlation between them using the correlation curve between the calculated borehole aquifer aquifer strata permeability and drilling fluid pumping capacity than the flow rate.
