伊犁盆地伊昭井田煤层煤质特征研究

伊昭井田位于伊犁盆地中西部,煤层资源储量36亿t。赋煤层位为侏罗世水西沟群西山窑组,共含煤12层,其中可采煤层6层,3号煤层和5号煤层为井田主采煤层。对各煤层特征进行了研究,总结了各煤层特征及赋存规律及各煤层煤质特征及工业利用方向。对指导伊犁盆地的煤炭勘查、开发利用及生产布局具有积极意义。

Study on Coal Characteristics of Coal Strata in Yizhao Coal Mine in Yili Basin

Yizhao coal mine is located in middle and western Yili basin, and coal reserves is 36 billions tons. Coal-bearing strata are Xishanyao formation in Jurassic Shuixigou group. It contains 12 layers of coal seam, among them, six layers are mining coal strata. No. 3 and No.5 coal layers are primary mineable coal beds. Through study on characteristics of each coal seam, characteristics and occurrence regularity of coal seams, characteristics of coal quality and the direction of industry utilization have been summarized. It has a positive significance for guiding the exploration, development and utilization and layout of production of coal resource in Yili basin.
