Due to the surface resources of an iron ore mine in Anhui Province are exhausted, to carry out the work in the open pit, the choice of mining methods and mining program to determine the key to off-production to achieve production, this paper addresses the issue, according to the actual geological situation of the mine, and reference to the many factors affecting the choice of mining methods, the initial and preferred choice of mining methods, so as to design a reasonable mining program, the study showed that the tentative use of the upward horizontal stratified approach to the road to fill method as a mining method, this mining method selection for the mine to achieve safe and efficient production of theoretical basis, has practical significance. After the study, it is shown that the upward horizontal stratified approach filling method is tentatively adopted as the mining method, and the selection of this mining method provides a theoretical basis for the mine to achieve safe and efficient production and has significance for practical application.
