Online first (OF) is the advance electronic publication of accepted articles that will be posted in upcoming issues. OF articles cannot be changed (including title, authors, etc.) or withdrawn (without regard to violation of publication ethics). Such an online publication differs from a traditional one in that it does not have fixed page numbers and is not tied to a specific journal issue. However, each such publication has a digital DOI identifier or EDN number for correct citation and is indexed by databases in the usual manner. That is, the article can be fully used in the lists of references and indicated in the reporting documents.
After the formation of the printed version of the volume, the missing information is added to the articles, but the URL address of the article and DOI or EDN number are not changed.
Advantages of Online First:
Online First articles are posted in Russian and English as they are approved by the editor-in-chief and as the editorial process is completed.
When citing an Online First article, you must include the author's name, article title, journal title, year of publication, and DOI or EDN number. Example of the citation format:

The use of stage-wise schemes in the development of deep quarries is one of the ways to increase the economic efficiency of mining a deposit and determining the optimal stage parameters remains an urgent task. Such parameters are stage depth, bench height, block length, etc. However, there is a wide range of values for these parameters. Therefore, to select the optimal values and evaluate the effectiveness of design solutions, it is advisable to use the net present value, which is an international notion. As a result of the analysis of data on deposits, a large number of variable indicators can be identified that presumably affect the efficiency of mining. The article proposes to divide all parameters of the quarry mining into two types: mine engineering and economic. The importance of each of them is determined by the measure of influence on the net present value. Thus, to assess the measure of influence of mining indicators, the average values of each of them are taken, and as a result of the alternating change of one parameter under study, the measure of its influence on the discounted income received is estimated. The results of the analysis of relevant factors, their evaluation and comparative analysis are important indicators that significantly affect the design decisions made and the effectiveness of the investment project.
