中文摘要：

采用电磁辐射技术及装备对薄煤层开采工作面进行电磁辐射监测,深入分析了薄煤层开采工作面电磁辐射显现特征.研究结果表明：采用沿空留巷巷道布置方式,受上区段采空区影响,工作面上巷电磁辐射强度及波动性都高于下巷;工作面来压前电磁辐射增强,来压后减弱,回采过程中电磁辐射呈现明显周期性;薄煤层冲击地压发生于电磁辐射短时间升高的峰后阶段,区别于厚煤层发生于电磁辐射增大到较高值一段时间,然后下降至低值并持续一段时间后.应用电磁辐射对薄煤层开采工作面进行应力分析及冲击地压预测时应充分考虑其特点,以提高分析预测准确性.

英文摘要：

The EMR technology and equipment is applied to monitor the thin coal seam workface and the EMR character is deeply analyzed.The result shows that if the gob-side entry retaining mode is adopted,the intensity and fluctuation of EMR in the upper lane are higher than lower lane owing to the influence of upper section adjacent goaf.EMR increase before weighting and decrease after weighting.During the process of mining,EMR present evidence periodicity.Rock burst happen after a short time of the peak of EMR in thin coal seam,which is different from thick coal seam.In thick coal seam,EMR increase before rock burst,after a period of time it decrease and stand in low value,then rock burst happened.When EMR technology is applied to analyze the thin coal seam workface stress and predicted rock burst,in order to raise veracity,the characters must be considered.
