本文是在木里煤田目前已有的地质资料及前人研究的基础上，以煤田地质学、沉积学、层序地层学以及岩相古地理学理论为指导，利用钻探岩心、露头、测井等数据进行了岩相古地理、层序地层学及聚煤规律的研究，总结了木里煤田沉积环境，建立了重新地层格架，分析了层序地层格架下的聚煤规律，并预测了有利成煤区。 木里煤田位于大通河上游盆地上游的拗陷带，受南部大通山北缘和北部托莱山对冲断裂组的制约，其构造形态为一个狭长的呈四边形展布的NWW—SEE走向的复式向斜。主要含煤地层为中侏罗统木里组和江仓组，江仓组下段为含煤地层，共含10层煤层；木里组上段为含煤段，共含10层煤层。木里煤田陆相湖盆沉积背景为主，发育辫状河三角洲等3种沉积体系、9种沉积相及多种沉积类型。本次研究建立了木里煤田含煤岩系层序地层格架及层序对比方案，总结出陆相盆地层序地层格架对煤层发育的控制规律，提出湖侵体系域可容空间的控煤作用。绘制了木里煤田的砂岩百分含量、泥岩百分含量以及砂泥比等各单因素等值线图，在此基础上基于层序地层恢复了含煤岩系的岩相古地理，分析了含煤岩系古地理环境的演化及其特征，最终提出了木里煤田聚煤模式。共预测了20余处成煤有利区，为下步找煤工作提供了地质依据。

This paper based on Muli Coalfield existing geological exploration data and previous studies, directed by coal geology, sedimentology, sequence stratigraphy, lithofacies palaeogeography theory, make use of drill core, outcrops and logging data to study the lithofacies paleogeography,sequence stratigraphy and coal accumulation law, summarized Muli Coalfield depositional environment, established a re-stratigraphic framework to analyze the regularities of coal accumulation sequence stratigraphic framework, and predict the vantage zone to form coal. Muli Coalfield located in Datong Basin upstream with depression restricted by Datong Mountain south of the northern margin and Tuolai Mountain hedge fracture group, the structural form of a narrow quadrilateral distribution of NWW-SEE trending syncline. The main coal-bearing strata of the Jurassic Muli group and Jiangcanggroup,Jiangcang group of lower coal-bearing strata, with a total of 10 layers of coal;The upper Muli group on coal segment , with a total of 10 layers of coal. Muli Coalfield in the continental sedimentary basin dominated background, braided river delta and other three kinds of sedimentary system, six kinds of sedimentary facies and a variety of deposit types. This study established the Muli coalfield coal-bearing strata sequence stratigraphic framework and sequence comparison program, summed up the continental shelf basin sequence stratigraphic control law for coal development, proposed lake transgression system domain accommodation space control coal effect. Draw a percentage of sandstone Muli Coalfield, shale and sand mud percentages than other single factor contour map, on the basis of the recovery phase of the coal-bearing strata of ancient geographical features based on sequence stratigraphy of rocks, summary the paleogeographic evolution and characteristics of coal-bearing strata, and proposed the Muli coalfield coal accumulation mode. And predicted more than 20 a favorable coal district, provides the basis for the next step to look for coal.
