The production is put into operation on 11/9/1998 and on 14/9/1999 respectively. The second-stage unit is 2 domestic 600MW subcritical units, and is put into production in 6 months of 2007, 19 days and 12 months of 2007, 5 days respectively. The three-stage unit is a 2 domestic 600MW supercritical unit, is put into production respectively in 12 months of 2010 and 13 days of 2011, has a total coal conveying belt length of 38.2 km and a total of 111 belt conveyors, has a farthest distance from a pit to a raw coal hopper of 8.39 km, and is one of the most complex, higher-automation and longest-conveying-distance coal conveying systems in China at present.
The following problems exist when the outdoor belt conveyor of the coal conveying system of the Yimin power plant operates in a low-temperature environment in winter due to the severe cold region:

(2) Because the adhesive tape glues a large amount of accumulated coal along the coal conveying system, a large amount of personnel are required to enter the site to clean the accumulated coal in order to ensure the safe operation of the coal conveying system, and the risk of great personal injury exists;
(3) Because a large amount of coal dust is accumulated along the coal conveying system, the risk of a large fire disaster exists;
(4) In winter, because the adhesive tape sticks coal, a crushing system needs to be forced to stop and clear coal every 11 months to 4 months of the next year at 7 to 9 points every day, and the coal supply of a unit and the work of coal external transportation and loading are seriously influenced;
the above problems seriously affect the safe production of the coal conveying system.
At present, most of antifreezing sticky agents used in high and cold areas in China are single agents with calcium chloride as a main component, and the agents have the defects of high corrosiveness, severe corrosion to a working surface adhesive layer and steel wires of a coal conveying adhesive tape, obvious strong drop of the adhesive tape after long-time use, and easy occurrence of hidden danger of adhesive tape interface fracture during equipment operation.
