SOTEM在厚覆盖煤矿采空区探测中的应用实例
Application cases of the short-offset transient electromagnetic method in detecting goafs with thick overburden in a coal mine
摘要
Abstract
Within a coal mine in Peixian County,Xuzhou City,brick-red Paleogene and Neogene strata were deposited in the faulted basin during the Cenozoic,with extensive Quaternary strata overlying various strata.The Quaternary,Jurassic,and Cretaceous strata exhibit thick overburden,up to over 500 m.This study explored the coal mine using the short-offset transient electromagnetic(SOTEM)method.Based on geoelectric conditions,reasonable observation parameters were designed to obtain the subterranean elec-tric structure within a burial depth of 1500 m.Goafs were detected at a burial depth of 900 m,with their delineated boundaries aligning with the mining situation of the coal mine.The results of this study serve as a reference for detecting goafs with thick overburden in North China-type coalfields.关键词
