青海省祁连县大拉洞柏杨沟矿区煤岩层对比研究

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。%Through study on sedimentary characteristics and variation law of coal bearing layers in Taiyuan group,using marker bed,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.Coal bearing strata, morphology,distribution and change characteristics of Taiyuan group have been determined.It has a cer-tain instructive effect on coal prospecting in the surrounding area.
