“…), and radioactive-elements ( 226 Ra, 238 U) [1,2]. Historically, PG was disposed of on the Earth's surface, which not only wasted a lot of resources, but also caused serious pollution of the atmosphere, soil, and water near the burial locations [3][4][5][6][7].…”

“…SEM analysis with the HELIOS NamoLab 600i (FEI, Lake Oswego, OR, USA). was used to find the micromorphologic development inside the cemented backfill samples [30]. Owing to the poor conducting performance of backfill, it was necessary to cover a layer of gold coating on samples to enhance the conductive properties of the samples in order to meet the inspection requirements.…”

“…Goaf is prone to cause disasters such as overlying rock caving, surface subsidence, and goaf waterlogging, which seriously affect the safety of mine production. The preparation of phosphogypsum into filling materials for mine filling can not only maintain the stability of surrounding rocks, reduce the surface subsidence, and enhance the recovery of resources [25][26][27][28], but it can also completely solve the problem of phosphogypsum stockpiling and ensure the sustainable development of mines [29][30][31][32][33].…”
