布尔台井田侏罗系中统延安组为盘区的含煤地层,是大型内陆湖泊三角洲沉积,沉积旋回结构,沉积岩性组合特征明显、清晰,在成煤理论指导下,综合运用层间距法、标志层法、沉积旋回对比、底板顺层追索法、测井曲线对比法对布尔台井田五盘区煤层进行划分及对比,可靠程度高,为后续煤层、煤质的评价,煤炭资源量的估算提供了可靠的资料基础。
佈爾檯井田侏囉繫中統延安組為盤區的含煤地層,是大型內陸湖泊三角洲沉積,沉積鏇迴結構,沉積巖性組閤特徵明顯、清晰,在成煤理論指導下,綜閤運用層間距法、標誌層法、沉積鏇迴對比、底闆順層追索法、測井麯線對比法對佈爾檯井田五盤區煤層進行劃分及對比,可靠程度高,為後續煤層、煤質的評價,煤炭資源量的估算提供瞭可靠的資料基礎。

In Buertai coal mine , the Yan’ an Formation of Jurassic System is the coal-bearing strata, and is a large inland lake delta sedimentary structure that the characteristics of sedimentary cycle and structure are obvious and clear .Based on the coal formation theory , using the methods of layer spacing method , key bed method , sedimentary cycle correlation , trac-ing method and logging curve correlation method , the coal seams in fifth region of Buertai coal mine were researched .The result can provides reliable basis for the evaluation of coal seam and coal quality and the estimation of coal resources .
