摘要
基于岩层与煤层中存在的自然γ射线具有显著差异的特性 ,提出了用自然γ射线方法解决综采放顶煤开采放煤过程煤矸识别问题 ;分析了煤矿煤岩中自然γ射线分布特征及该方法的适用性 ;
Based on the physical phenomenon that the amount of the gamma ray radiation in rock is different from the amount of the gamma ray radiation in coal,the paper puts forward the method for coal rock detection in top coal caving.The distributing characteristic of natural gamma ray in different type rock and the applicability for coal rock detection by natural gamma ray are analyzed.The paper also discusses dynamic problem for coal rock detection and influence of top coal falling process to coal rock detection.This is worthy of solving coal rock detection in top coal caving.
