综合测井资料在福泉大湾磷矿富水性特征分析中的应用

Application of comprehensive logging data in the analysis of characteristics of Fuquan Dawan phosphate mine

水文地质条件是矿山勘探过程中一项极其重要的工作,水文地质工作的好坏决定了后期矿山开采的经济性和安全性,准确地对地层富水性进行划分,则是水文地质勘查中重要的一环。在贵州白岩背斜地区以往的磷矿勘查中,人们通常笼统的将整个灯影组作为含水层,从而使得计算的涌水量远大于实际,给矿山的防水治水带来了极大的浪费。本文通过综合地球物理测井方法对大湾矿区地层的富水性进行研究,并定量的划分出勘查区内地层富水性,从而为水文地质勘查提供准确的物探依据。

Hydrogeological conditions are an extremely important work in the process of mining exploration.The quality of hydrogeological work determines the economy and safety of mining in the later stage.It is an important part of hydrogeological exploration to accurately divide the water abundance of strata.In the past phosphate exploration in Baiyan anticline area of Guizhou Province,people generally regard the whole Dengying Formation as the aquifer,resulting in the calculated water inflow far greater than the actual amount,which caused great waste to the mine waterproofing and control.In this article,through comprehensive geophysical logging methods,the authors studied the water abundance of the strata in the Dawan mining area,and quantitatively divided the water abundance of the strata in the exploration area,thereby providing accurate geophysical basis for hydrogeological exploration.
