Abstract: Opening-up (or opening) of working benches at opencast mining is carried out first of all for the purpose of creation of conditions for the output of extracted mineral resources. However, mining operations are usually accompanied by removal of significant volumes of waste rock. These volumes are also moved to the storage site by means of a corresponding opening-up.
This is why opening-up of working benches plays an important role in the open pit operations and has a significant impact on the technical and economic performance of the enterprise.
The choice of rational variants of opening-up is carried out by consideration of this or that party of the given problem: volumes of mining works and kinds of opening workings out (trenches, shafts, adits), depth of laying of external trenches, quantity of mine workings, locations of external and internal trenches, forms of a route of internal trenches, stationarity of opening workings, transition from opening by trenches to underground workings out, application of the special equipment or creation of constructions for moving of cargoes.
These and other issues of working benches opening-up in the course of open pit mining are in the focus of attention of many researchers.
This article summarizes the existing classifications of methods of opening and proves that it is necessary not to extend the classification of methods, but to divide them into methods and schemes. Examples of schemes for opening real quarry fields are given.

Key words: opening surface mining development system method of opening scheme of opening quarry field opening system opening workings
