| 摘 要： | 分析了邢台东庞煤矿2220高架综采工作面坑透中出现的"透视阴影异常"现象,认为同一工作面内随地层倾角增大坑透场随之衰减,由此造成的"透视阴影异常"与隐伏构造无关。

| Abstract: | The phenomenon of "penetration shadow anomaly" which is appeared during the radiowave penetration at the No.2220 full mechanized face in Dongpang mine,Xingtai,is analyzed.It is believed that the field intensity of radiowave penetration is attenuated with the increase of the dip angle of strata at the same face,and the resulted "penetration shadow anomaly" is unrelated with the concealed structures. |

| Keywords: | radio wave penetration method dip angle of strata field intensity attenuation |
