Gangue filling material and application
The invention provides a gangue filling material and application. The gangue filling material comprises gangue slurry and gangue paste, the gangue slurry is prepared from the following components in parts by weight: 50 to 80 parts of gangue A, 10 to 20 parts of aluminum oxide powder, 10 to 20 parts of silicon powder and 0.6 to 40 parts of water reducing agent; the gangue paste comprises 50 to 95 parts of gangue B, 4 to 20 parts of cement, 1 to 50 parts of fly ash and 0.5 to 40 parts of an auxiliary agent; in the gangue filling material, the weight ratio of gangue slurry to gangue paste is (1.0-1.2): 1; the particle size of the gangue A is smaller than that of the gangue B. The gangue filling material provided by the invention has good fluidity, the strength after setting and hardening meets the requirements, the requirements of filling mining and goaf filling construction can be met, meanwhile, the preparation is simple, the materials are easy to obtain, and the cost is lower.
本发明提供了一种矸石充填材料及应用。该矸石充填材料包括矸石浆料和矸石膏体;按重量份计,矸石浆料包括:50~80份的矸石A、10~20份的氧化铝粉末、10~20份的硅粉以及0.6~40份的减水剂;矸石膏体包括:50~95份的矸石B、4~20份的水泥、1~50份的粉煤灰以及0.5~40份的助剂;矸石充填材料中,矸石浆料和矸石膏体的重量之比为(1.0~1.2):1;矸石A的粒径小于矸石B的粒径。本发明所提供的上述矸石充填材料具有较好的流动性,凝结硬化后的强度符合要求,能够满足充填开采及采空区充填施工需求,同时制备简单,材料易得,成本更低。
