THE FORECAST OF COAL CONTAINING ROCKS SUSTAINABILITY ON THE BASIS OF GEOPHYSICAL DATA
The developed methodology of rocks stability forecasting on the basis of coal containing rocks lithological composition and their physic-mechanical properties obtained with the involvement of geological-geophysical information, allows to produce a reliable forecast of coal containing rocks sustainability. The article reveals the main factors affecting the determination of reliable indicators of the strength properties and lithological composition of the South-Yakut coal basin rocks. The analysis of the geological-geophysical methods testing results in the study of lithology in sections of the wells has shown an opportunity to use this approach in the exploration of coal deposits. The correlations between the geophysical parameters and the main physical and mechanical properties of coal deposits of the South – Yakut basin were presented. The article presents the data showing the possibility of using the obtained correlations (equations) for the prediction of physical-mechanical properties of rocks according to the data of geophysical research and wells exploration. The possibility of application of the developed forecasting technique of mining rocks stability for making predictive maps of stability in the coal deposits exploration is demonstrated.
