Research on the development of rock-coal interface monitor in top-coal caving mining
SPIE Proceedings, 2005The strong radioactivity such as shale stone is more than 10 times higher than that of coal and even the medium radioactivity such as pelitic sandstone is 5 times higher than that of coal. Therefore, the natural gamma rays in the coal-rock mixture mainly comes from the refuse and it is feasible to make sure the rate of the refuse in coal-rock mixture ...
