直升机TEM测量影响因素分析

直升机TEM被广泛应用于矿产、水文地质勘查等领域,该测量方法在国内还处于发展阶段,且飞行难度大,总结其野外测量流程、分析野外测量影响因素,对于今后直升机TEM飞行作业具有实际意义。笔者结合雄安新区白洋淀和雄县两个测区实测资料,对直升机TEM野外测量主要环节中存在的影响因素进行了分析,并提出了相应的建议,如机型选择、直升机起降点、天气、飞行高度、速度、飞行计划及测量系统稳定性监控等,为今后直升机TEM测量飞行提供参考经验。

An analysis of the influencing factors of helicopter TEM survey

Helicopter TEM is widely used in mineral resources,hydrogeology and other fields.Summarizing the field survey process and analyzing the influencing factors of field survey have practical significance for future helicopter TEM flight operations.Based on the actual survey data from the two survey areas of Baiyangdian and Xiongxian in Xiong'an New Area,the authors analyzed the influencing factors in each link of the helicopter TEM field survey,investigated the model,and put forward suggestions in such aspects as the choice of take-off and landing points,the flight in different weathers,the flight height and speed,flight plan formulation,survey system stability monitoring and other aspects,thus providing reference experience for future helicopter TEM survey.
