The uniaxial compressive strength of compounded phosphorus gypsum after 28 d of curing
period was tested to be more than 1Mpa.Phosphorus gypsum can be used as materials for the backfill of stope.By comparison and
numerical simulation,cut and fill mining method with middle—deep drilling holes and ore transportation by blasting force was
selected as the optimum mining method in Kaiyang Phosphorus Mine.
