青海省祁连县大拉洞-柏杨沟矿区煤岩层对比研究

Comparative Study on Coal Strata and Rock Strata in Daladong-Baiyanggou Mining Area in Qilian County of Qinghai Province

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.
