| 简介 |
The present invention relates to a method for manufacturing the low-strength, highly flowable mine goaf filling agent composition utilizing an eco-friendly solidification material as a bonding agent while utilizing mine wastes of debris, mine tailing as an aggregate and system therefor, and more specifically to a method for manufacturing the filling agent composition of a flowable concrete form and a system therefor by utilizing debris of rock and gravel forms and mine tailing 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 manufacturing method for low-strength, highly flowable mine goaf filling agent according to the present invention includes; 1) a stage of preparing mine wastes with a particle size in the range of tailing 5mm~40mm and mine tailing with a particle size smaller than 5mm by crushing debris; and 2) a stage of preparing a solidification material; and 3) a stage of mixing 80~120 parts by weight of the mine tailing, 15~45 parts by weight of the solidification material. 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.[Reference numerals] (11, 31) Debris storage; (12) Fixed quantity supplier; (13) Crusher; (14) Vibrating screen; (21) Filler storage; (22) Complex mixer; (23) Aggregate meter; (24) Fission meter; (25) Liquid meter; (32) Mine tailing storage; (33) Solidification agent storage; (34) Water-reducing agent storage; (35) Thickener storage; (AA) More than 40mm; (BB) 5-40mm; (CC) Below 5mmCOPYRIGHT KIPO 2014 |
