Abstract
This article is devoted to the actual problem of dump formation during the enrichment of coal mines in the Karaganda basin in the conditions of the Central processing plant "Vostochnaya". Based on initial data on mining and geological conditions, physical and mechanical properties of rocks, and well-known analytical studies, the calculated parameters of a stable dump are given, including its maximum height and tier parameters, taking into account the technology of dump formation. Calculations were made on the stability factor of the blade base and calculations on the stability factor on the blade body. Based on the known theoretical knowledge, research and calculation were performed on a numerical model to determine the stable parameters of the tiers and the external rock pile as a whole, and recommendations for the optimal number and height of the tiers were developed. One of the main tasks in the productions, processing and enrichment of coal is to ensure the stability of rock dumps during the operations of the enterprise. As a rule, this is the search for the most optimal solutions for the location of storage of rock waste of enrichment, usually in the form of dumps in the designated areas.
