Analysis Of Geological Anomalies Correlation With The Characteristics Of Curve Of Radio Wave Penetration In Huainan Coal Mine

With the improvement of mechanization of coal mining technology, geological tectonic occurrence within the working condition requirements plus more and more important. Radio wave penetration technology is widely adopted in mines for geophysical prospecting. However, there is no reliable correspondence or corresponding mode and the lack of theoretical analysis between the value of the radio wave penetration changes and geological anomalies. So the characteristics of the curve of radio wave perspective for different geological anomaly have important significant value and application value.Papers on radio analysis and summary of the results of radio wave penetration of Huainan mine area, study the change law of field intensity value and attenuation coefficient of geologic anomaly in different coal seam. Based on the basic theory of radio wave penetration, is put forward using the "field strength increment" in data processing to reduce the interference of background field, improve the accuracy of anomaly interpretation, and validation by underground experiments.Thesis choose typical coal seam working face of huainan mining area, studied the relationship between the fault and thin coal district and other different geological anomalies of the radio wave curve, and some response law of different towards, divide fault and coal seam thinning belt at the curve of radio wave perspective is obtained, can provide guidance for the pit through interpretation of radio waves. Fault in radio wave curve characteristics mainly appeared inflection point, the curve steepening, into and away from the different occurrence of fault when the curve change speed is different; Coal seam thinning belt in the curve characteristics of radio waves are mainly appeared inflection point, curve is a straight line or arc shape, relative to the fault curve is relatively flat.
