12%A new algorithm for the optimal stope design problem is proposed. It is based on a previous methodology developed by Bai et al. (Comput Geosci 52:361–371, 2013a) where a cylindrical coordinate system is used to define geomechanical restrictions and to find the optimal stope around an initial raise. The new algorithm extends …

The vertical inline pump is a single-stage single-suction centrifugal pump with a curved inlet pipe before the impeller, which is widely used in where the constraint is installation space. In this paper, with the objective functions of efficiencies at 0.5Qd, 1.0Qd, and 1.5Qd, a multi-objective optimization on inlet pipe and impeller was proposed to broaden the efficient …

Pit Optimization – How I View It. One of the first steps in open pit mine design is the pit optimization analysis. Pit optimization is used to define the most profitable pit shell (or nested pit shells) for a given set of economic parameters. The economic parameters include the metal prices, process recoveries, and operating costs.
As the width of the entry wall decreased, the integrated vertical stress, induced by two adjacent mining panels, coupled with each other and experienced an increase on the entry wall, which inevitably weakened the stability of the entry. Therefore, mining with coal pillars always involves a tradeoff between economy and safety.

Gradient descent for machine learning. Optimization is the most essential ingredient in the recipe of machine learning algorithms. It start s with defining some kind of loss function/cost function and ends with minimizing the it using one or the other optimization routine. The choice of optimization algorithm can make a difference between getting a good accuracy …
In 1978, H.M. Wells published the paper "Optimization of mining engineering design in mineral valuation", which proposed maximizing the present value ratio (PVR) in order to find the optimal production rate. PVR is the ratio of PVOUT (the present value of positive cash flows) to PVIN (the present value of negative cash flows).

Phase 2: Simultaneous Optimization. To truly receive the most value from a project, simultaneous optimization of mining sequence, cut-off grade, stockpiles and blending is performed. Whittle's SIMO module performs the optimization of all items in one step, producing a higher NPV solution than a sequential optimization of the same parameters.
