Effect of different machinery and rolling times on the physical property of reclamation soil in coal area
This experiment sets up the simulation experimental area based on the national natural science fund,in which we simulate the main types of reclamation in coal mine area.After two years natural aging,collecting the surface soil samples (0~20 cm) used for experimental analysis,in order to explore the change rule of soil bulk density,porosity,temperature,conductivity and moisture content under different construction machinery and rolling times,so we could find the optimal processing conditions.This topic of the text has a significant role for land reclamation in coal mining area,and will provide reference during construction work to a certain extent.The result shows that change rules of soil environment factors are different when using different construction machineries,and soil physical properties are closest to the normal soil when adopting the combination of crawler dozer × 5 rolling times,which expresses that the process result is the best under this condition.
