Based on research of the distribution of coal-bearing basin,coal-bearing strata,tectonic regularities,sedimentary environment and coal-accumulation features,divides tectonic type in the region,namely the total structural types in south rim of Songliao Basin is structures resulting from linear shearing,with the Tianshan-Yinshan latitudinal tectonic belt and Shuangliao-Tieling-Dagushan meridional tectonic belt.Different orders and different levels tectonic controlled occurrence and distribution of minerals,formed three different coalfield sedimentary type with different features,EW-SN structures is the tectonic framework of this area.the way their mode and direction of motion,and its derivative branch tectonic are important factors in distribution of basin-controlling coal accumulation and deposition types.Distribution and sedimentary type of controlling coal-accumulation basin,determines the development degree of coal-accumulation.
