ABSTRACT
As a result of coal mining, the surface subsidence and ground fissures were occured, and a lot of land resources were occupied by the waste dump which formed from coal gangue. In mine area land reclamation work, the layered covering, layered rolling engineering technique method has been used when covering soil on the subsidence land and waste dump. This method caused the density of soil after reclamation significantly higher than original soil. It was not conducive to the growth of plants and reduced the effects of land reclamation.
