This article considers the need of developing the method for evaluating the condition of excavation roof using the method of geoinformation analysis. The article also describes the existing research and roof control methods and analyzes their advantages and disadvantages. On the basis of this analysis the authors of the article establish the requirements for the method developed. The authors suggest using the geoinformation technologies for modeling, analyzing and evaluating excavation roof condition. We compile a list of tasks which are to be accomplished to develop the method. The paper presents the list of information objects, the database and the properties of these objects. The approach to database implementation is chosen. The database structure is presented. The article also describes the technology of geospatial data analysis, various sections data required for the development evaluation method. The analysis and selection of software for 3D modeling are made up, and 3D models of excavation sites are built.

This article considers the prerequisites to the development of technologies and a method of computer analysis of the influence of the coal mining process on the state of the earth’s surface in the district of the breakage face. The paper presents an algorithm for the implementation of preparatory works for analysis of the influence of coal mining on the state of the earth’s surface in the district of the block in the form of activity diagram, as well as the tools that are necessary for this analysis are considered. The technologies of 3D modeling of massif by means of FreeCAD are considered, and the analysis of solids formation methods, characterizing rock formation, is carried out. For more accurate calculations and analysis, the finite element model of massif must be built with detail, that is, to break down solids into smaller elements. The article represents a technology, the application of which will be implemented in cooperation with rock geographic information systems, which be capable of a detail analysis and assessment of the impact of coal mining on the surface within the second working.
