摘要
】介绍了中、低能γ射线在煤和矸石中的透射原理，建立了以煤和矸石的质量吸收系数比率Ｋ为判别依据的煤矸在线识别模型，并对其在应用中存在的若干问题进行了讨论。
The paper introduces the principle of the transmission of low and high energy γ-rays in coals and gangues, and presents an on-line identification model for coals and gangues based on the mass attenuation radio K of dual energy γ-rays. Some problems in the application of the model are also discussed in the paper.
