1983年元月,国务院发布指示,要求各地区、各部门积极发展煤炭洗选加工,合理使用煤炭,逐步由主要燃用原煤改为主要燃用商品煤;要求全国统配煤矿从1983年开始,逐步做到按用户需要供应商品煤。 根据这个指示精神,本文作者认为:河北省煤炭系统在合理使用煤炭方面正在进一步改善,预计会获得更好些的经济效果,但目前对筛选的作用尚重视不够,还没有下大功夫去挖潜。本文谈的主要是筛分分级问题。
January 1983, the State Council issued a directive requiring all regions and departments to actively develop coal washing and dressing processing, rational use of coal, and gradually change from the main burning of coal to the main burning of commercial coal; require the country’s coal mines from 1983 onwards, Gradually to do according to user needs supply of coal products. According to the spirit of this directive, the author of the paper believes that the coal system in Hebei Province is making further improvements in the rational use of coal and it is expected that better economic results will be obtained. However, the role of screening is not sufficiently emphasized yet and great efforts have yet to be taken to tap the potential. This article is mainly about the classification of screening problems.
