Deep Prospecting Prediction of Dahongshan Iron Mine Based on Wide-area Electromagnetic Method
With the continuous expansion of the scale of production,the hidden crisis of mineral re-sources in Dahongshan Iron Mine has gradually emerged,and the deep part is an important direction for the breakthrough of prospecting in this area.Under the comprehensive study of the geological conditions of Da-hongshan iron-copper mine,the wide-area electromagnetic method is used to detect the distribution of stra-ta and fault zones within 3 000 m underground by referring to the electrical distribution characteristics and magnetic induction intensity of the identified main ore bodies,combined with geological,drilling,geophysi-cal and other information.After interpretation,the non-ore-induced anomalies are excluded,and four ab-normal areas are delineated as favorable areas for prospecting.A total of 18 fault structural belts were divid-ed,including 4 known fault structures corresponding to the work area and 14 uncontrolled or concealed structures.
