Abstract
The purpose of this work is to find the analytical equation of the isoline value of minerals in the open mining of complex ore deposits. As the initial data, we used the data of the cross section of a complex deposit, where three types of minerals (main and two associated) are developed. In the Cartesian rectangular coordinate system are given coordinates of points that allow to build an approximation of the desired equation. The example of application of the method of least squares for construction of the specified dependence is considered. This algorithm is implemented in a computer program based on Microsoft Excel. Numerical results were obtained and graphs were plotted.
