Development of a new risk assessment method with geomatic engineering approaches in underground mining workplaces

Underground mine workplaces are classified as very dangerous workplaces in terms of the difficulty of working conditions and the intensity of hazards that may occur in the working environment. Therefore; It is an important issue that occupational health and safety measures in underground mine workplaces are carried out rapidly by performing risk analyzes and also that these analyzes include understandable and visual elements. Underground mining production maps; it differs from other maps and plans related to the surface in terms of numerical and alfanumerical information, symbology and dimension features. In addition, they are technical documents that show the hazardous areas and sources of danger that may occur in underground mining workplaces. In terms of mining legislation; mining production maps have to be submitted to MAPEG annually for workplace safety in digital and 3D. In this research, the necessity and importance of mining production maps were examined in terms of legislation. In the light of the developing technologies, the applicability of the 3D mining production maps has been proved by integrating them to a Mining Information System, namely MIS. A series of studies have been carried out to create proactive dynamic risk maps by utilizing the questionable and analyzable features of mining production maps integrated into MIS. It has been determined that the success of converting these maps to risk maps depends on the use of risk index points as the third dimension in the three-dimensional map. Risk assessment methods known in the legislation do not include risk scores that are appropriate for this subject. Therefore, a risk index scoring system has been developed within the scope of this thesis. Thus; the index scores determined for the different hazard groups in each production area are drawn and coloured as risk index contours on the risk map. In addition, dynamic risk maps were obtained by placing three-dimensional symbology on it. As an experimental application; for Acılık coal seam in Kozlu production areas of Turkey Hardcoal Enterprise were discussed. Risk index score systems and risk maps for dust and noise hazards has been developed for the Western Acılık panel on these coal seam.
