摘要
可保盆地位于小江断裂带西支主干断裂(嵩明—华宁断裂)东侧,盆内断裂及褶皱构造发育,以南北向及北北东向为主。含煤地层为新近系中新统,4个含煤段共含煤30余层,其中可采27层,煤层总厚度110.87m。受西侧盆缘断裂F41及基底控制,厚煤带围绕宋家地背斜倾伏方向呈带状分布,在垂向上煤层明显向东超覆迁移。
The Kebao Basin is situated on the east side of the western offshoot major fault （Songming-Huaning fault） of the Xiaojiang faulted zone. Fault and fold structures are well developed in the basin with mainly NS and NNE strikes. Coal-bearing strata is belonged to the Miocene Series, Neogene System, including 4 coal-bearing sectors, totally 30 more coal seams, in which 27 mineable, coal seam total thickness 110.87m. Controlled by basin boundary fault F41 and basement, the thick coal zone encircling the Songjiadi anticline plunging direction, takes on zonal distribution, and coal seams are obviously overlapping migrated toward east vertically.
