Practical effect of audio frequency electric perspective in an iron ore laneway
音频电透视仪在铁矿巷道中的试验效果

Because of complicated causes of formation, the shape of metal ore is mostly irregular. Vague distribution of ore body between laneways often result heavy over expenses of exploitation. Following the method commonly used in the detecting of geological structure and water gush in coal mines, we carried out a test exploration of audio-frequency electric perspective in No. 8 laneway of Zhaogezhuang iron-ore mine. Getting rid of the disturbance from the railway in the laneway that troubles DC electric exploration method deadly, the audio-frequency electric perspective gets a good geological exploration result about the distribution of ore body. The practical exploitation check shows that the exploration result is well in accordance with the actual distribution of ore body between laneways. The test offers a good method for the exploration of metal ores in laneways.
