The present invention relates to mine goaf filling agent compositions with a low strength and a high flowability by utilizing mine wastes of debris, mine tailing as an aggregate and eco-friendly solidification materials as a bonding agent, and more specifically to filling material compositions having a form of concrete with flowability by utilizing debris of rock and gravel forms and mine tailings as particles in the order of sand among wastes remaining after dressing valuable resources from abandoned mines in the past as an aggregate, and mixing with eco-friendly solidification materials without using cement as a bonding agent. The low-strength, highly flowable mine goaf filling agent compositions according to the present invention comprise; 80-120 parts by weight of the mine tailing with a particle size below 5mm; and 15-45parts by weight of the solidification material; and 1-5 parts by weight of the fluidization material; and 1-5 parts by weight of the thickener for 100 parts by weight of the mine debris with a particle size in the range of 5mm-40mm.;COPYRIGHT KIPO 2014
