Through analysis of the factors causing the problems and the necessity of renovation, it is proposed to replace the 7011^#scraper conveyor with a belt conveyor. Practice shows that the renovation has made it possible to ensure safety operation and create a favorable economic result due to noticeable reduction of fault rate, maintenance work, power consumtion, cost and frequency of replacement of parts of equipment.
