【摘要】：新型AGRSS航空伽马能谱测量系统于2013年由核工业航测遥感中心自主研发,经历江苏六合、黑龙江嘉荫、甘肃礼县等测区十余万测线千米的生产实践应用,取得了较好的测量效果,推动了AGRSS系统的改进升级.本文简要介绍AGRSS系统的参数指标、系统刻度与应用状态等,通过研究直升机搭载AGRSS系统在甘肃礼县测区所采集的航空放射性测量数据信息,基本查明了该地区放射性核素区域分布特征,天然放射性核素K、U、Th水平显现"中部岩体出露区偏高、周边地层中低水平"的特点;并结合地质资料,分析典型铀矿床、金矿床的航空伽马能谱特征,结果认为新型AGRSS系统采集数据信息在矿产勘查中是有效可靠的;说明AGRSS系统对高海拔且地形切割剧烈山区的适应性较强,仪器性能稳定;同时表明AGRSS系统在地质填图、铀及多金属矿产勘查中应用效果显著.
[Abstract]:In 2013, the new AGRSS airborne gamma-ray energy spectrum measurement system was independently developed by the Nuclear Industry aerial Survey and remote Sensing Center. It has experienced the production and application of more than 100,000 km of surveying lines in Liuhe, Heilongjiang, Jiayin, Gansu Province, etc., and has achieved good results. This paper briefly introduces the parameter index, system scale and application state of AGRSS system, and studies the airborne radioactivity measurement data collected by helicopter carrying AGRSS system in Lixian area of Gansu Province. The regional distribution characteristics of radionuclides in this area have been basically ascertained, and the characteristics of natural radionuclide Ku U Th level showing that "the outburst area of the central rock mass is on the high side and the surrounding strata are low", and the typical uranium deposits have been analyzed in combination with geological data. The results show that the new AGRSS system is effective and reliable in mineral exploration, which indicates that the AGRSS system has a strong adaptability to high altitude and severe terrain cutting mountainous area, and the instrument performance is stable. At the same time, the application of AGRSS system in geological mapping, uranium and polymetallic mineral exploration is remarkable.
