One of the common methods of surface mining is the use of the open pit method. Usually, for designing the ultimate pit limit in open-pit method requires seven stages. The design steps include preparing the initial block model, estimating the grade block model, calculating the cutoff grade, calculating the economic block model, selecting the optimum algorithm, choosing the technical limitation of extraction, and selecting the suitable software. Several different algorithms, such as floating cone and its corrected models, Korobov and its corrected models, dynamic programming, Lerch and Grossman and other algorithms were provided. The condition of using these algorithms in the 3D space for open pit mining is the use of suitable software. However, the software that defines most of the optimal algorithms and enriches science seekers theoretically so that they can easily compare the design results of various optimal limits in open pit mines has not been introduced completely and clearly. Based on this, the authors of this article have prepared software to include most of the algorithms related to the selection of the ultimate limit of open-pit mines, and this scientific gap is filled. Therefore, in this paper, a new software was created based on Visual C++ language and it was called Pit Designer software. In this new software, 10 different ultimate limit design algorithms are defined along with 7 conflation algorithms. Also, This new software has been validated using two analytical and comparative methods. An analytical method was used to validate the two-dimensional block model and a comparative method was used to validate the three-dimensional model using Pitwin32 software. The outcomes of validation indicate that the final results obtained from the Pit Designer software are completely similar to the results obtained from analytical and comparative methods.
