Abstract

Summary. Purpose. Evaluation of the integral index variation values (II) obtained by stability assessment methodology, assessment of the safety factor values of sustainability, for Inhulets career conditions. At the moment there are different approaches to the assessment of the stability of pit walls, but the most common method of using a safety factor. That is the basis for calculating the integral index, and includes more advanced evaluation boards career stability. The purpose of this article is to evaluate the integral index variation values (II) obtained by the methods of the stability assessment and parallel evaluation of sustainability safety factor values, for Inhulets career conditions. Results. As a result provdeniya assess variability has been found that the use of methods of information dimensionless quantities can be used for implementation of information factors that are different in nature and have an impact on the condition of stability of the rock mass, as well as with the results of using this method to obtain the integral index, which will provide the most accurate assessment of the solid state like currently and in the future. Methodology details dimensionless quantities can be used for implementation of information factors that are different in nature and have an impact on the condition of stability of the rock mass. Made a summary assessment of variations in the integral index and safety factor. Based on the fact that a combination of features is considered homogeneous when values of the coefficient of variation of less than 40% can be said that this deposit has a relatively homogeneous structure and can be perceived as a single entity, divided into a set of mutually influencing zones. Scientific novelty. For the first time offered the integral index, allowing regionalize board iron quarries on the complex factors that determine the slope stability of the rock mass. Practical significance. The evaluation of the variation of the integral index and the safety factor for career Inhulets conditions.
