摘要
金属资源短缺已成为限制我国经济高速发展的重要因素,发展井中物探工作已成为深部找矿的重要方法之一。井中三分量磁测系统在过去取得了很好的找矿效果,但因为受其精度(200~400nT)的限制,只能应用于寻找磁性较强的矿床。为了扩大井中三分量磁测系统的应用范围,我们研制出新的高精度三分量磁测系统,其精度可达到25nT,可以用来寻找中、弱磁性的有色金属矿床,为社会经济的发展贡献有限力量。
The shortage of metal resources has become an important factor which restricts the rapid economic development of China, and developing borehole geophysics has become one of the important ways for the deep geophysical prospecting work. Borehole three - component magnetic measurement system had made great successful results for prospecting in the past. Because of its precision (200 -400nT) restriction, the system was used only to find a strong magnetic deposit. In order to expand its application area, we de- veloped a new high -precision three -component magnetic measurement system, with the precision up to 25nT, which can be used to find the weak magnetism of non - ferrous metal deposits. This system will make some contribution to the socio - economic development.
