摘　　要：三维高密度电阻率法应用领域十分广泛,该文以良庄煤矿41102工作面为例,介绍了该方法在矿井工作面底板富水性探测中的应用。根据高密度电阻率法基本原理,对41102工作面进行数据采集、数据处理、数据解释等过程,建立该工作面底板以下地层3维数据体,直观反映了这些地层的富水性情况。采用切片技术,对易发生突水的徐灰、奥灰划分富水区域,以此对工作面防治水工作做出指导。Three-dimensional high density resistivity technique is widely applied. Taking 41102 working face of Liangzhuang coal mine as example, this paper introduces its application in water content detection of mine working face floor. Based on the basic principle of high density resistivity method, the data of No.41102 working face are collected, processed and analyzed. As a result, 3 dimensional data system of stratum under the working face is set up to intuitively reflect water-bearing characteristic of the stratum. Adopting the slice technology, water abundance areas in Xujiazhuang and Ordovician limestone which are subject to water inrush are parted. The partition of water abundance provides guidance to the prevention and control of water inrush in working face.
