Application of Transient Magnetic Prospecting Method in Detecting Water-rich Abnormal Areas of Coal Seams in Loess Tableland Area
GAO Xiao-wei;China Coal Research Institute,Xi ' an Branch;
On the basis of describing the geological situation of hongliulin mine and combining with logging data,this paper analyzes the physical parameters of various strata in the mine area. Through examples, the key technologies of transient electromagnetic detection data processing-terrain correction and interference wave correction are pointed out. The basic principles of transient electromagnetic method data interpretation are expounded. Facts have proved that it is feasible to use transient magnetic exploration technology to find water-rich abnormal areas of coal seam in loess tableland area.
