本文首先分析了礦井探測(cè)中遇到的信號(hào)干擾種類(lèi)，結(jié)合噪聲信號(hào)的特點(diǎn)，提出了基于
電磁感應(yīng)的礦井探測(cè)方法，給出了其原理圖和設(shè)計(jì)原則。然后詳細(xì)論述了電磁感應(yīng)探測(cè)方法的具體實(shí)現(xiàn)，給出了各主要測(cè)試參數(shù)的計(jì)算公式，明確了在探測(cè)過(guò)程中需要采集的各種信號(hào)。為了驗(yàn)證提出的電磁感應(yīng)探測(cè)方法，最后采用了MATLAB 建立了仿真測(cè)試模型，并給出了仿真測(cè)試結(jié)果。

Abstract:This paper has first analyzed the disturbance type which in the mine pit survey meets, the union noise signal characteristic, proposed based on the electromagnetic induction mine pit survey method, has produced its schematic diagram and the principle of design. Then in detail elaborated the electromagnetic induction survey method concrete realization, has produced each main test parameter formula, has been clear about each kind of signal which needs to gather in the survey process. In order to confirm the electromagnetic induction survey method which proposed, finally used MATLAB to establish the simulation test model, and has produced the simulation test result.
