METHOD FOR MANUFACTURING FUNCTIONAL SOIL MATERIAL USING THE SLUDGE OF A COAL MINE

摘要

PURPOSE: A method for manufacturing a functional soil material is provided to prepare a covering soil material by mixing coal mine sludge powder with a solidifying agent and to prepare landfill liner material by mixing the coal mine sludge powder, fly ash and bentonite. CONSTITUTION: A method for manufacturing a functional soil material using coal mine sludge powder comprises the steps of: a sludge pulverizaton step(S10) for pulverizing coal mine sludge obtained from coal mine; and (S20) a mixing step for mixing the coal mine sludge powder obtained through the sludge pulverizaton step with a solidifying material.
