Abstract:With the increasing human demand for mineral resources, many domestic and foreign mines have gradually entered deep mining. High stresses in deep areas often cause instability of the stope, which affects the economic and technical indicators of mining. The existing mining parameters are no longer applicable to deep ore bodies. A reasonable mine structure parameter is theoretically calculated for a mine to increase the mine's production capacity, reduce the ore loss rate and lean rate, and reduce the ore mining cost.Production practice shows that the economic benefits of the new scheme are significantly increased, the mining cost is reduced by 16 yuan per ton, and the ore loss rate and depletion rate are decreased by 2.5% and 1.9% respectively. The mining of other similar mines provides a reference.
