根据同一煤田内同一煤层的形成条件基本稳定,煤中灰分所吸附的放射性物质与煤灰分含量有关,利用煤层的自然伽玛值和煤层灰分进行回归分析,求出了回归方程,并计算出了煤中的灰分。
According to the formation of the same coal seam in the same coalfield, the formation conditions are basically stable. The radioactive materials adsorbed by the coal ash are related to the coal ash content. The regression equation is calculated by using the natural gamma ray of the coal seam and the ash content of coal seam, Ash in coal.
