Abstract:

Aiming at the problem that the traditional manual weaving for making underground mine production plan is complicated and the charts are difficult to display,based on the theory and method of multi-objective programming,a multi-objective programming model is established taking net present value,grade and metal quantity for goal,a feasible production plan is solved quickly and accurately,which avoids the limitation of ordinary linear programming,3D visualization technology is used to clearly show the spatial distribution of underground engineering and their logical relationship.A set of feasible production planning process is provided, which simplifies the work of production technology.It is proved by an example of one iron mine that the method can effectively optimize the production plan of the mine and provide the basis for mine operation and decision-making.

Key words: underground mine, multi-objective programming, 3D visualization, production plan, medium and long term, topological network, mathematical programming
