Abstract: In order to be able to produce the saleable coal products that can find a ready market, improvement work is made by the plant through joint effort with the stress simultaneously laid on the following 5 aspects: improvement of raw coal pretreatment process, improvement of management of coal cleaning, storage and handling operations, improvement of the efficiency of cooperation between different departments, practice of the check-up policy, and intensification of equipment maintenance. Through the improvements the plant is finally made possible to produce the grade-5 clean coal product—a low-ash low-sulfur steelmaking coal. This enables the plant to have a greater variety of products, make the most of its brand advantage and become possible to realize order production.
