摘要
甘肃宁县中部勘查区位于鄂尔多斯盆地南部,含煤地层主要为侏罗系延安组,可采煤层有3层(煤2,煤5,煤8),煤类简单。根据勘查样品测试成果和沉积环境分析,论述了煤岩地层特征,并对工业和元素分析的结果进行了讨论。本区煤是在水介质逐渐咸化的成煤环境条件下聚集形成,变质程度低,属低—中灰、特低—中高硫、高热值弱粘煤,结渣性中等,是很好的动力用煤。
The Ningzhong exploration area is located in the southern of Odors Basin and the coal-bearing stratum is Yan＇an Formation of Middle Jurassic.Based on the test results of exploration samples and the analysis of sedimentary environment,the paper analyzed the characteristics of coal-bearing strata and discussed the characteristics of coal quality and its use.
