综合探测技术在小煤窑采空区探查中的应用
Application of Comprehensive Detection Technologies in Exploration of Goafs in Small Coal Mines
摘要
Abstract
To ascertain the distribution range and water-rich characteristics of goafs around coal mines,and to guide disaster prevention and safety production in the mine,a comprehensive multi-parameter geophysical exploration was carried out using the Transient Electromagnetic Method(TEM)and microtremor prospecting,based on an analysis of the topographic and geological features of the mining area and pre-existing survey data.The exploration results show that:TEM can effectively identify the spatial distribution range of goafs and their water-rich characteristics;Microtremor prospecting can more accurately delineate the boundary positions of goafs;A total of 10 goafs were delineated across the area,and borehole verification showed an accuracy rate of over 80%.The study demonstrates that the coupled electro-seismic response model formed by TEM and microtremor prospecting significantly improves the reliability of interpretations,providing a practical basis for selecting detection methods for goafs in small coal mines.关键词
