摘要
介绍了我国目前煤炭资源状况,回顾了我国选煤业的发展现状,分析了煤炭洗选的作用及煤炭洗选对煤炭清洁利用的影响。指出重介选煤是我国选煤技术优先发展领域,模块化选煤厂是我国选煤厂设计和建设的新模式,并指出煤炭的洗选加工是提高煤炭利用率、节约运力、增加煤炭企业经济效益、减少污染物排放减轻大气污染的最经济、有效的途径,是煤炭清洁利用的基础与主导组成部分,是发展洁净煤技术的重点,是煤炭企业的必经之路,对环境保护和实现我国煤炭工业的可持续发展有着重要的战略意义。
The present situation of coal resources and the present development status of coal industry in China have been reviewed.And the effect of coal preparation and the influence of coal preparation technology on clean utilization was analyzed.Meanwhile,it points out that heavy medium coal preparation is prior development domain of our country’s coal preparation technology and modularity of coal preparation plant is the new model of coal preparation plant design and construct,coal washing and processing is the most economical and efficient way to improve coal utilization ratio,save transport capacity,increase economic benefit of coal enterprise,reduce pollutant emission and air pollution,the basic and dominant component of coal clean utilization,the emphasis of developing clean coal techniques,the only way of coal enterprise.What’s more,it is strategic significance for environmental protection and sustainable development of coal industry in China.
