[ 1 ] - Physical Model Test and Numerical Simulation Study of Deformation Mechanism of Wall Rock on Open Pit to Underground Mining (RESEARCH NOTE)

This paper is based on the open pit to underground mining practice of Daye Iron Mine. The influence mechanism between high-steep slope and non-pillar sublevel caving method is studied by using physical model test. Firstly, engineering geological properties of the choosing typical research section is analysed and generalized. Secondly, the system of open pit to underground mining is developing a...
