Abstract
The determination and optimization of stope structure parameters is of great value in reducing the ore loss and dilution in the mining process, improving the production capacity of the stope, increasing the workload of mining and mining, reducing the investment cost of the mine and improving the mining efficiency. Based on this, this paper first analyses the parameter changes of stope structure parameters without sill pillars in metal mines, and then studies the optimization of structural parameters of stopes without sill pillars in metal mines based on orthogonal test method.
