基于瞬变电磁法的采空区含水体分布探测
Detection of goaf water-contained distribution based on transient electromagnetic method
摘要
Abstract
Aimed at identifying goaf water-contained hierarchical structure,distribution range and water-bearing situation,this paper draws on the difference of rock,coal,goaf and aquifer resistivity in different occurrence,as is evident in a mine of Jidong Country in Heilongjiang Province and introduces the efforts to achieve ground detection using transient electromagnetic instrument,analyze the change of goaf water-contained secondary filed,catch low resistance abnormal body and thus inverse imaging.The results reveal the occurrence of well-developed fissures and faults in local detection zone,the presence of water-contained goaf in No.1 and No.3 anomalies,and the presence of water-contained fissure and in No.2 anomaly area.The transient electromagnetic method detection produces results consistent with those from field drilling and promises a reliable technology in mine water control,mine flooding accident emergency rescue and coal resources integration.关键词
