Abstract

The invention discloses a mine remediation simulation experiment system for biomass ash fluidized stabilized soil, and particularly relates to the technical field of mine remediation. The interference degree of the complexity of the chemical components on the solidification uniformity of the solidified soil is analyzed by measuring the chemical components of the biomass ash; and the adaptability of the fluctuation characteristics of the chemical components of the ash to the rheological property is evaluated in combination with the geological conditions of the mine restoration area. On the basis of the interference degree and the adaptability, the construction feasibility of the ash flow-state solidified soil is judged; under the condition of good construction feasibility, the migration and diffusion risk is evaluated by measuring the metal ion activation energy change rate, and the succession dynamic evaluation structure stability of the microbial community is analyzed. Through comprehensive analysis of rheological property adaptability, diffusion risk and microbial community stability, the repair reliability is evaluated, scientific guidance is provided for mine repair, and the application effect of the biomass ash fluidized solidified soil in mine repair can be effectively optimized.
