超低航磁找矿方法与技术研究

为了快速、有效地找寻隐伏矿及深部矿,笔者研发了超低航磁找矿系统。该方法以动力三角翼飞行器(体育器材)为载体,依靠其飞高低、飞速慢、磁性弱优势,配备较为先进装备,经过精心调试与补偿,该系统具有较高精度,通过重复线飞行,计算均方差为±4 nT,优于地磁测量精度。根据找矿的特点,研究了空地异常关系,给出了不漏矿找矿比例尺的确定方法,引入大数据定律确定调平高度,以台劳级数进行高度、磁场双调平。5年来,在国外7国,国内3省进行了找矿示范应用,取得了较好效果。该系统精度高,成本低,效果好,有很强的独立自主性。

Innovation of the ultra-low aeromagnetic prospecting method and technology research

In order to discover the deep concealed metal deposits quickly and effectively, the ultra-low aeromagnetic prospecting system is innovated by authors. The system is based on the dynamic delta wing aircraft (sports equipment) as the carrier, relied on its technical advantages of flying at low elevation, slow speed and weak magnetic interfere, and equipped with advanced equipments, well-adjusted and compensed. The system has the high precision by flying through repeated line, the calculated mean square error of plus is -4 nT, which is better than that of the traditional geomagnetic measurement . According to the characteristics of the prospected metal deposits, the relationship between the abnormal space was conducted, and the mineral prospecting scale was determined for the purpose of not loosing the prospecting targets. Also the laws of big data was introduced for balancing leveling height. The height and the magnetic field in Tyler series were double levelled. This method has been applied in the prospecting of metal deposits in severn foreign countries and three provinces home in the past five years, and sounding prospecting effects have been obtained.The system has high precision, low cost and good effect, therefore, it is easily operated and approved as a new, quick and effective prospecting technology.
