Abstract: The strength value for the cemented filling body in a copper mine in Fujian is designed. After comparing the design strength values under different methods, we obtain the strength design scheme for filling body of deep X1 ore body filling mining: the bottom of the long top is 1.93 MPa, the middle is 1.53 MPa, the bottom of the square top is 2.67 MPa, and the middle is 2.12 MPa.
