ARTICLE ANNOTATION

quote
In the article " Almaliq KMK" JSC Thermal Power Center (IEM) using the ash and non-combustible part of the coal used in heating steam boilers, the advantages and possibilities of filling the mined space and its technical implementation are calculated. The calculation and analysis of economic indicators shows the inconsistency of these modifications to the goal Under the conditions of the Kovuldi mine, the cost of the solidifying filler for 1m3 was developed, and based on the developed mining plan, it was required that the share of additional crustaceans in this amount does not exceed 22%. Based on this condition, the economic calculation of the proposed option is determined. Economic indicators satisfy the requirements of their share in the total cost amount. The specifications, on the other hand, do not meet the requirements of the 25,000 m3 fillings envisaged in the mine works plan, which means that it is not possible to provide the amount of additional coagulation enhancers needed to complete the annual plan. The less the share of additional capacity-enhancing agents in the total cost amount, and the less the supply satisfies at least the annual need, this is considered to be of additional economic purpose.
