Analysis of heavy metal pollution in vicinity soil of coal gangue dump——Taking Zhongmacun Mine of Jiaozuo as an example

In order to investigate heavy metal content concerning Cr, Pb, Cu and Mn, soil samples were collected using fan shape allocation method in the vicinity of Zhongmacun Mine, Jiaozuo. The results show that coal gangue pile causes various heavy metal pollution to ambient soil, and that heavy metal pollution has a trend that the farther from the pile, the weaker the contamination is. The main factor affecting the movement of heavy metals in topsoil is the prevailing wind.
