Zusammenfassung:	PURPOSE: A method for stabilizing soil using coal mine sludge is provide to stabilize heavy metal-polluted soil by suppressing elution and flowability of heavy metal within polluted soil using coal mine sludge and to prevent secondary contamination of polluted soil. CONSTITUTION: A method for stabilizing soil using coal mine sludge comprises the steps of: (S10) a level setting step for setting the level of polluted soil; (S20) a powder spraying step for spraying the coal mine sludge powder on the set polluted soil; (S30) a powder mixing step for mixing the sprayed coal mine sludge powder with the polluted soil; (S40) a tampering step for tampering a mixture layer of the coal mine sludge powder and polluted soil; (S50) a loamy soil spraying step for spraying loamy soils on the tampered mixed layer; and (S60) a finishing step for uniformly spreading the sprayed loamy soil.
