Study on the structural parameters of the upward horizontal layered filling method in deep gold mine

The quality and stress of the surrounding rock of the ore body have a significant impact on the selection of underground structural design parameters.To further understand the impact of different burial depths on the structural parameters of the mining site, this article analyzes the mechanical properties of Fushan Gold Mine under different burial depths through mechanical tests.On this basis, theoretical research and numerical simulation are conducted on the structural parameters of the upward horizontal layered mining in the Fushan Gold Mine area using empirical calculation and numerical simulation methods.The stress and deformation structures of three mining structural parameter schemes are analyzed and compared, and the optimal parameters of the mining structure under different burial depths are proposed.
