Understanding Geometric Constraints

Mine planners must consider geometric constraints in open pit mine planning. This ensures the mine operates efficiently, safely, and within regulations. These constraints can significantly influence the design and planning of an open pit mine. By addressing them early in the planning process, mine planners can develop more accurate and realistic mine plans. This comprehensive approach helps in maximizing the economic returns of the mining project while minimizing potential risks and geometric challenges.

Integrating Geometric Constraints

En un proyecto minero, El planificador de la mina debe dimensionar con precisión cada operación unitaria para determinar el conjunto de equipos más adecuado para las condiciones existentes.. MiningMath integrates operational parameters as constraints within the objective function, rather than applying them post-pit optimization. This methodology ensures solutions that adhere to operational criteria while maximizing NPV. Como resultado, it leads to more effective data utilization and uncovering opportunities that might be overlooked with stepwise methodologies and arbitrary assumptions (leer más aquí).

Modeling Geometric Constraints with MiningMath

MiningMath allows users to include geometric constraints y, como consecuencia, encontrar soluciones más cercanas a las operaciones mineras reales. Puede guiar geometrías incluyendo anchos de minería y de fondo, longitudes de minería, tasas máximas de avance vertical, y forzar/restringir áreas mineras. All these are briefly described next.

Anchos mínimos
open pit operational constraints with minimum bottom width

Ancho de fondo: this represents the minimum area at the bottom of the pit. You must maintain a sufficient bottom width to ensure the stability of the pit and provide enough space for the final excavation and haulage operations.

Ancho de minería: this refers to the distance between one pit and another. It ensures that the pits are spaced adequately to allow for safe and efficient mining operations, including the movement of equipment and personnel

Minimum Length

Mining Length: this is the smallest allowable horizontal distance from one pit to another within a given period. It helps to maintain a continuous and efficient mining process by preventing overly close pits that could hinder equipment movement and access.

Tasa de avance vertical

Tasa de avance vertical: this refers to the vertical distance mined during each period. It ensures that the mining progresses at a controlled pace, preventing excessive vertical excavation that could destabilize the pit walls and surrounding areas.

Mining area constraints

Minería forzada: define the minimum depths, geometrías, or areas that you should mine at specific timeframes.

Restringir la minería: define the minimum depths, geometrías, or areas that you should no mine at specific timeframes.

Force and Restrict mining: reach the exact shape of a pit by defining the same surface for both Force and Restrict mining at the same timeframe.

Transform Your Open Pit Mine Planning with MiningMath's Geometric Constraints

Con el método de un solo paso de MiningMath, su motor de optimización, puede descubrir oportunidades que la planificación manual o por pasos podría pasar por alto. Al final, este motor puede optimizar la utilización de recursos y puede mejorar los resultados del proyecto. Transform your mine planning process by leveraging these operational constraints in the optimization process and take your mining projects to new heights of efficiency and success.
