By studying structure characteristics and sedimentary filling sequences, this paper discusses the Jurassic tectonic and sedimentary evolution process the study area, provides the basis for exploration and exploitation of coal resources in Muli Coal field. The result shows that:there are two groups of faults in the research area, which are NW-NWW thrust fault and NE-SW right lateral strike slip fault. NWW-NW fault formed in the late of Yanshan period isdeveloped. NE-SW right lateral strike slip fault is later and it is the outcome of Himalaya. Fold morphology is linear folds and thick folds, which is the results of Himalaya. Fault-fold constitutes a one-way thrust type compound syncline, one-way thrust type compound anticline, hedge type compound syncline. Delta facies, meandering river facies and lake facies are the main sedimentary facies in Jurassic of Muli Coal field.The coalfield went through of rift sedimentary period (Jurassic), the period of uplift and denudation stage (cretaceous and the Oligocene), wide basin sedimentary period (Miocene), and the period of Fold-thrust
