| 摘 要： | 吊舱式直升机频率域电磁、磁综合系统(以下简称“吊舱系统”)采用新型的宽带技术,数字化程度较高,系统较为灵活,尤其适合于地形较为复杂地区的矿产和水工环勘查工作。但由于吊舱系统在复杂山区飞行难度大,且没有实际工作经验,因此通过选择3个测区的吊舱系统试生产工作,在测量方法技术,数据处理方法和成果解释方面,以及基础地质研究、矿产勘查、地下煤火勘查方面均取得了显著成果。解决了航空电磁方法探测地下煤火区的电性结构特征问题,以及航空电磁方法直接寻找良导矿体的关键问题,弥补了航磁间接寻找多金属矿的不足,并取得了明显的勘查效果。

| Abstract: | Towed bird helicopter-borne frequency domain electromagnetic and magnetic synthetic system (hereafter towed bird system) with new broadband technology, high digitized degree and flexible system is very suitable for mineral, hydrological, engineering, environmental exploration in complex terrain, but it′s hard to work in complicated mountainous regions, and we didn′t have practical experience. Basing on trial-produce in three survey regions, we acquired outstanding achievements in survey method and technique, data processing, data interpretation, basic geological research, mineral exploration, and underground coal fire exploration. It worked out the problem of feature of electrical property in coal fire area, and the key problem of searching conductive ore body directly with aero electromagnetic method. It remedied the weaknesses in searching polymetallic ore body with aero-magnetic method indirectly, and had brought very good prospecting effects. |
