摘　　要：虎林煤盆地位于黑龙江省东部赋煤带内,属于断陷型沉积盆地,基本构造特征为受敦-密深断裂带控制和影响,是在其后期发展形成的煤盆地,构造相对简单。虎林盆地主体为北东向展布,是以中、新生代沉积为主的沉积盆地,主要含煤地层为古近系虎林组和新近系富锦组。虎林盆地煤层多为复杂结构,煤层由薄煤层-厚煤层都有发育,在富煤中心形成的煤层较厚,向外侧扩展变薄至尖灭。The Hulin coal basin is situated in the eastern Heilongjiang coal hosting zone, a fauh depression typed sedimentary basin. Basic structural features have controlled and impacted by the Dunhua-Mishan deep-fracture zone, so that a coal basin developed subsequently with relatively simple structures. Principal part of the basin extended northeasterly, thus a mainly Mesozoic and Cenozoic deposits sedimentary basin. Main coal-bearing strata have Paleogene Hulin and Neogene Fujin formations. Coal seams in Hulin Formation mostly have complex structures, with thicknesses from thin to thick. Generally, coal seams in the center of coal-rich zone are thicker, then gradually thinning outward up to pinch out.
