摘要
采空区的探测对于保障矿区作业安全有重要作用。以SQUID磁梯度仪为基础,使用计算机实现模拟测试场地的仿真测试,并对模拟场地区域的地下磁异常进行磁梯度探测,使用反演算法获得磁异常源的方位、几何轮廓和距离,同时较好地排除了该场地其他磁异常源的干扰,以此验证了SQUID磁梯度仪用于地下磁信息探测的可行性。对SQUID磁梯度仪应用于矿区采空区的探测有指导意义。
The detection of goafs plays an important role in safeguarding the safety of mining operations.Based on the SQUID magnetic gradiometer,the simulation test of the simulation test site was performed using a computer,and magnetic gradients were detected in the underground magnetic anomaly of the simulation site.The inversion algorithm was used to obtain the azimuth,geometric profile and distance of the magnetic anomaly source.At the same time,the interference from other sources of magnetic anomalies on the site was well ruled out.The feasibility of the SQUID magnetic gradiometer for the detection of subsurface magnetic information was verified.The SQUID magnetic gradiometer has guiding significance for the detection of mining goafs.
