摘　　要：含煤层位与围岩存在电阻率差异,可以用高频大地电磁法(EH4)来圈定含煤层位,但是数据会受到静态效应的影响.通过在云南某矿区进行了试验研究,并采用了相位法对数据进行处理,克服了静态效应影响,结果与地质资料相吻合,成功地圈定含煤层位,获得了较好的效果.There exists electrical can be used to delineate the coal resistivity difference between coal strata and surrounding rock, therefore, EH4 strata. However, the data may be influenced by static effects. We have done experimental researches in an orefield of Yunnan Province, applying the phase method to process the data and eliminating the static effect. The results are in compliance with the geological materials, thus we successfully delineate the coal strata and accomplish better effects.
