Abstract:

Purpose. To develop the model and computation algorithm for evaluation of reserves of amber using orthogonal grid schemes of deposits.

Methodology. We have applied the methods of mathematical statistics and modeling. The choice of the weight function that provides minimal variance of the mean estimator is a complex mathematical problem.

Findings. The problem of estimation of the reserves of the mineral dispersed within a deposit of rectangular form with staggered wells has been formulated and solved. The algorithm of conformal mapping has been developed.

Originality. To estimate the amber reserves we have applied one of the mathematical modeling methods, namely the finite difference method and numerical conformal mapping. This is related to the problem of numerical conformal mapping of a simply connected plane polygon into the parametric rectangle.

Practical value. The method of constructing grids using numerical conformal mappings can be applied to the reserves evaluation problems in case of mineral deposits of curvilinear form, which often occur in practice.
