Изобретение относитс к анализу материалов электромагнитными методами и может быть использовано дл определени содержани магнитного железа в стенках горных выработок на железорудных месторождени х.The invention relates to the analysis of materials by electromagnetic methods and can be used to determine the content of magnetic iron in the walls of mine workings in iron ore deposits.
Цель изобрете;ни - повьшение точности и достоверности анализа за сче устранени вли ни неровностей по- верхности горной вьфаботки.The purpose of the invention is to reduce the accuracy and reliability of the analysis by eliminating the influence of the irregularities of the surface of the mining process.
Способ осуществл ют следующим образом .The method is carried out as follows.
Намагничивают исследуемую среду входным преобразователем электромаг- нитными пол ми различной частоты в диапазоне 0,,0 кГц, в пределах которого регистрируема ЭДС обусловлена в основном магнитной восприимчивостью среды. Значени двух фиксиро- ванньк частот из указанного диапазона выбирают эмпирически применительн к конкретной конструкции датчика. Регистрируют разность ЭДС дл разных The test medium is magnetized by the input transducer by electromagnetic fields of different frequencies in the range 0, 0 kHz, within which the recorded EMF is mainly due to the magnetic susceptibility of the medium. The values of two fixed frequencies from the specified range are chosen empirically for a particular sensor design. Register the difference in emf for different
частот. Эта ра ность ЭДС пропорциональна содержанию магнитного железа в слое, определ емому различной глубиной принокновени полей разной частоты .frequencies. This emf difference is proportional to the content of magnetic iron in the layer, which is determined by different depth of the field of different frequencies.
