Mixing these materials will result in an increase in the amount of coarse particles in the minesoil, allowing more infiltration and percolation of rainfall, decreasing surface runoff, and hence reducing erosion and sedimentation. Also, since more rainfall enters the minesoil and moves deeper, there is more moisture available for plant growth.

Abstract In the Tanshan area, in the Liupanshui Basin, abundant oil shale resources are associated with coals. We analyzed the cores, geochemistry of rare earth elements (REE), and trace element of oil shale with inductively coupled plasma mass spectrometry technology to define the paleo-sedimentary environment, material source, and geologic significance of oil shale in this area. The results ...
