可控源音频大地电磁法在陷落柱富水性勘查的研究
Study on Controlled Source Audio—frequency Magnetotelluric(CSAMT)Method in the Exploration of Water—richness of Collapse Columns
摘要
Abstract
Multiple collapse columns have developed in a coal mining area in Qinshui area in Shanxi prov-ince.But the water content inside the columns has not been clearly defined,which poses a great risk to the safety production of the mine.In order to effectively cope with this severe situation,it has been decided to use controllable source audio magnetotelluric method to conduct in-depth exploration of the water rich properties of collapsed columns.This method aims to accurately determine the development range of col-lapse columns and comprehensively analyze their geological morphology and hydrogeological characteris-tics.By analyzing the controllable source audio magnetotelluric response characteristics of the collapse col-umn,analyzing the structures of the collapse column with different resistivity combinations,and establis-hing a segmented structured model of the collapse column,it can help relevant personnel intuitively and accurately understand the internal structure and water supply situation of the collapse column,and provide scientific and reasonable water prevention and control measures for subsequent development.关键词
