摘要
为解决矿山隐蔽采空区安全隐患问题,笔者采用地质雷达法、高密度电阻率法、瞬变电磁法、地震法、可控源音频大地电磁法和音频大地电磁法等探测手段,对内蒙古自治区苏尼特右旗巴彦敖包萤石矿进行了采空区探测方法优选研究。综合该萤石矿床的地质-物性特征与物探结果,采用地质雷达和高密度电阻率法联合探测的技术组合可以有效探测其中隐蔽采空区的分布,并成功查明了研究区90 m深度范围内隐蔽采空区的空间分布情况,钻孔验证和3D激光扫描也充分证明该探测方法组合准确可行。
To address the safety hazards associated with hidden goafs in mines,the authors utilize an array of detection techniques,including geological radar,high-density resistivity,transient electromagnetism,seismic methods,controllable source audio magnetotellurics,and audio magnetotellurics.Focusing on the Bayan Aobao area in the Sunite Right Banner of the Inner Mongolia Autonomous Region,this research specifically targets the optimization of goaf detection methods for fluorite deposits.By integrating the geological and physical characteristics of the deposit with the results of geophysical exploration,it was determined that a combined approach of geological radar and high-density resistivity methods is highly effective in detecting the distribution of hidden goafs.This combination successfully identified the spatial distribution of hidden goafs up to a depth of 90 m in the study area.The accuracy and feasibility of this detection methodology were further corroborated by drilling verification and 3D laser scanning.
