新型AGRSS航空伽马能谱测量系统在甘肃礼县地区铀及多金属矿产勘查中的应用效果
|
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.
New Airborne Gamma Spectrometry System( AGRSS)was independently developed by Airborne Survey and Remote Sensing Center of Nuclear Industry in 2013. It has been applied to production practice in some zones including Jiangsu,Hei Long Jiang and Gansu province,which has gained a better effect and expedited the improvement and upgrade of the AGRSS system. This paper briefly introduces the performance index,calibration coefficient and collecting data quality evaluation of the AGRSS system,etc. By researching the data collected through using the helicopter airborne gamma-ray spectrometry system to carry out the high-precision gamma spectrometry survey in Lixian of Gansu province,it finds out that the distribution characteristic of the gamma energy spectrum in this region,natural radionuclides K, U, Th level presents the characteristics that rock mass is on a high level in the middle part of this zone,and its surrounding assises are on a low level. It also finds a better reliability of information of new AGRSS system in geological mapping and radioactive mineral prospecting by combining geological information and analyzing the characteristics of aeronautical gamma spectrometry of typical uranium and polymetallic deposits. It indicates that new AGRSS system has strong adaptability in the mountains which is cutting sharp terrain and high altitude,and the stability of the equipment. At the same time,it shows the obvious effects of the AGRSS system on regional geology,and the exploration of uranium and polymetallic deposits prospecting.
