InSAR Mapping Technology in Manganese Ore Survey

为准确高效地监测锰矿矿区的地表沉降情况,研究基于改良干涉合成孔径雷达技术及概率积分法构建联合地表沉降监测方案。对该联合方案进行实证研究,发现该方案的绝对误差为32.1 cm,相对误差为15.8%,运算时间为44.6 s,低于其他对比方案。且联合法的最大地表沉降为-259.5 cm,与实际水准监测结果相吻合。综上结果可知,研究提出的联合法可解决传统干涉合成孔径雷达技术无法监测大梯度地表沉降的问题,且其检测准确度性能及运算时间性能也优于其他对比方案,具有实际应用价值,可为锰矿矿区的地表沉降情况提供有效的支持。

In order to accurately and efficiently monitor the surface settlement of manganese ore mining area,we think that the improved surface settlement monitoring model on interference synthetic aperture radar technology and the joint surface settlement monitoring scheme are constructed.The empirical study of this joint method shows that the absolute error of this scheme is 32.1 cm,the relative error is 15.8%,and the operation time is 44.6 s,which is lower than the other comparison schemes.The maximum surface settlement of the joint method is -259.5 cm,which is consistent with the actual leveling monitoring results.Overall results,the joint method can solve the conventional interference synthetic aperture radar technology cannot monitor the problem of large gradient surface settlement.Its detection accuracy performance and computing time performance is better than other comparison scheme,which has the practical application value.It can provide manganese mine surface settlement of more effective support.
