As one of the main industrial solid wastes, there are a large number free alkaloids, chemically bound fluoride, and heavy metal ions in Bayer process red mud (BRM), which difficult to remove easily pollute groundwater as result open storage. In order realize large-scale application BRM backfilling aggregate for underground mining simultaneously avoid polluting groundwater, material characteristics were analyzed through physical, mechanical, chemical composition tests. The optimum cement–sand...
The mining of layered soft bauxite under coal seams (BCS) will cause serious underground goaf disasters and surface Bayer process red mud (BRM) pollution. In order to realize the safe efficient BCS, feasibility recycling BRM as a backfilling aggregate was explored. A series tests were conducted prevent pollution diversion from storage goafs, numerical simulation analysis carried out based on FLAC3D protect overlying seam. results show that: action encapsulation, solidification inhibiting...
