Numerical Investigation on Stratum and Surface Deformation in Underground Phosphorite Mining Under Different Mining Methods
With the ending of deep-concave open-pit phosphorite extractions and gradual exhausting of shallow mineral resources, stoping of phosphorite seams has entered or will enter into underground mining. Particularly for excavating slightly inclined thin and medium-thick phosphorite orebodies, roof and su...
