The rationale for the development of a method for assessing the roof conditions of mine workings in the conduct of actual mining using the method of geoinformation analysis

Abstract

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.
