摘要
工业的发展、浅层矿的枯竭、原有地表地质仪器功能的局限等,都要求有新的、功能强大的、精度高的、能探测深层、弱磁场的磁力仪的诞生,来完成攻深找忙的重任。磁通门磁力仪就是应运而生的一种有效测量井下磁场的磁力仪。它利用了普遍存在的磁通门现象,具有体积小、重量轻、分量测试相对简单、可靠性好、坚固、抗干扰能力强、量程范围宽等特点。一般磁通门磁力仪主要由探头和测量电路两部分组成,可将静态磁场信号转化成电能测到的信号,并取出有用信号,寻找异常磁场,找到磁性矿。
Along with the development of industry, human need more mineral, but the superficial mineral was limited, can't meet the need, so we must search the deep-seated mineral. The instrument we used now can't completed this new task, so the more powerful instruments should be made. The 3-components flux-gates magnetic instrument is one of this kind of instruments, which can research the underground magnetic riel& It is small, light, firm, hoard-range, and less influenced by noise. It's major components are circuit and sensors, they sense and change the static magnetic signal to the signal that can be received by electricity. Then get the useful signal, so this instrument can find the abnormal magnetic field, which means find the mineral with magnetism. (by Liu Jia et al)
