摘要
可控源音频大地电磁法(CSAMT)是探测采空区的有效方法之一,为验证CSAMT对可溶性盐矿采空区溶腔的探测效果,对龙归硝酸盐矿采空区使用CSAMT进行测量。根据测线剖面特征推断采空区溶腔顶板的埋深位置,对比分析地震波反射法的剖面特征,验证了CSAMT测量的可靠性。
The controlled source audio-frequency magnetotelluric(CSAMT)is an effective method to detect goafs.To verify the detection of CSAMT on goafs of soluble salt mine,it was used in Longgui Nitrate Mine.The buried depth of roof of brine cavern was inferred by profile characteristics.The reliability of CSAMT measurement was verified by comparing and analyzing the profile characteristics of seismic reflection method.
