Abstract
The approaches to the creation of databases that accumulate various information about the deposits of solid minerals are considered. The structure of the database of rocks of the Elginskoe coal deposit and the procedure for filling with information of its constituent sections are proposed. It is shown that the database use provides the highest level of information and analytical support of the geotechnological problems focused on the safe mining and completeness of reserves extraction from the subsoil. A number of coalfield models have been built using specialized software based on the database. The stability analysis of overburden massif of the coalfield has been carried out and geomechanical conditions of open-pit sides have been evaluated.
