Comparative Study on Coal Strata and Rock Strata in DaladongBaiyanggou Mining Area in Qilian County of Qinghai Province

摘要:

通过研究太原组的沉积特征及聚煤变化规律，采用了标志层、煤岩层组合特征、层间距、测井曲线形态等方法，对矿区内煤层、岩层进行了综合对比。确定了该区主要煤层的赋存层位、形态、分布及变化特征，对周边地区找煤工作具有一定的指导作用。

Abstract:

Through study on sedimentary characteristics and variation law of coalbearing layers in Taiyuan group, using markerbed, coal and rock assemblages, layer spacing and logging curve and other methods, a comprehensive comparison is made on coal and rock in the mining area. Coalbearing strata, morphology, distribution and change characteristics of Taiyuan group have been determined. It has a certain instructive effect on coal prospecting in the surrounding area.
