AI Technical Summary
Technical Problem
Existing methods for disposing of coal ash face limitations in storage capacity, necessitating costly expansion of ash disposal sites to prevent scattering, which increases land acquisition and construction costs.
Method used
A method involving the production of embankment material from clinker ash, fly ash, and cement, followed by sequential construction and hardening of embankments and coal ash slurry layers, with controlled moisture content and application of scattering suppressants, to raise and stabilize coal ash without scattering.
Benefits of technology
Enables the stacking of larger amounts of coal ash while minimizing location and cost, ensuring structural integrity and preventing scattering, even over extensive areas.

Abstract
To provide a method for raising coal ash that can raise a larger volume of coal ash while reducing the location and cost of raising the coal ash, and while preventing the scattering of coal ash. [Solution] The method comprises an embankment material generation step (step S10) for generating embankment material, a first embankment construction step (step S11) for forming a first embankment with the embankment material, a first embankment hardening step (step S12) for hardening the first embankment, a coal ash slurry generation step (step S13), a first layer raising step (step S14) for raising the coal ash slurry A, a coal ash slurry hardening step (step S15) for hardening the coal ash slurry A, a second embankment construction step (step S16) for forming a second embankment, a second embankment hardening step (step S17) for hardening the second embankment, and a second layer raising step (step S18) for raising the coal ash slurry A within the second embankment, wherein the cement content of the coal ash slurry A is 50 kg / m³ 3 That's all.
