大同地区侏罗纪和石炭纪原煤煤泥特性研究

The Research of Coal Slime Feature of Jurassic and Carboniferous in Datong Area

大同地区侏罗纪煤炭资源已基本枯竭,目前新建矿井及老矿延伸后,开采的基本上为石炭纪原煤,其灰分较侏罗纪原煤成倍增加,煤质变差。文章就大同地区石炭纪、侏罗纪煤泥特性进行比对分析研究,提出合理的矿井延伸接替原煤洗选煤泥系统处理工艺及参数。

Jurassic coal resources have been largely dried up in Datong area. At present, after the extension new mines and old mine, basically carboniferous coal is mining, and its ash multiply, the coal quality becomes poor. This paper analyzes slime feature of carboniferous coal and Jurassic coal in Datong area, and puts forward the reasonable processing technology and parameter of coal slime system for mine extention to replace raw coal washing.
