Abstract: The design and construction of filling retaining wall in goaf are directly related to filling quality, production capacity and cost-effectiveness.In this paper, the force of filling retaining wall in goaf of A'erhada lead-zinc mine is analyzed, and the total pressure, maximum bending moment and position of action point of filling retaining wall under different filling height are calculated.At the same time, according to the three calculation methods of compressive strength, shear strength and permeability conditions, the structural thickness of filling retaining wall is analyzed, and based on this, the construction design scheme of filling retaining wall in the goaf of this mine is put forward.The results show that when filling the goaf, the first filling height should not exceed 2.5 m in theory.It is suggested that the thickness of the retaining wall in site construction should not be less than 0.5 m.The research results can provide references for the construction design of filling retaining wall in goaf under similar engineering conditions.
