Zusammenfassung:	The invention discloses a loess fly ash-based coal mine filling material, and a filling method thereof. The loess fly ash-based coal mine filling material comprises water, a main material, an auxiliary material, and an additive; the main material is composed of loess and fly ash; the auxiliary material is composed of cement, quicklime, and gypsum; mass ratio of loess to fly ash ranges from 1:1.5 to 1:3; the mass of auxiliary material accounts for 30 to 33% of the mass of the loess fly ash-based coal mine filling material; and the mass of the additive accounts for 5 to 7% of that of the loess fly ash-based coal mine filling material. According to the loess fly ash-based coal mine filling material, loess is used for replacing a part of fly ash in traditional filling materials, so that cost is reduced as far as possible with ensured filling material performance.
