山西静乐舍科勘查区主要含煤地层为上石炭统太原组和下二叠统山西组，通过对区内地质成果分析，本区太原组沉积环境由河控三角洲到潟湖、潮坪交替出现，期间发育两次碳酸盐台地，岩性主要以灰岩、泥岩、中粗砂岩和粉、细砂岩为主，含主要可采煤层9煤层；山西组主要为三角洲平原分流河道相、泛滥盆地相和泥炭沼泽相，以砂岩、粉砂岩、砂质泥岩为主，含主要可采煤层4-1、4煤层；4-1号煤层属大部可采的较稳定煤层，4和9号煤层属全区可采的较稳定煤层；本区主要煤类均为焦煤，资源量丰富，煤质较好，具有较高的开发价值。

Main coal-bearing strata in the Sheke exploration area, Jingle, Shanxi belong to Upper Carboniferous Taiyuan Formation and Lower Permian Shanxi Formation. Through exploration area geological data analysis, considered that the sedimentary environment of Taiyuan Formation has been experienced from fluvial-dominated delta to alternating lagoon and tidal flat, meanwhile, two times of car?bonate platform developed;lithology is mainly limestone, mudstone, medium-coarse sandstone, siltstone and fine sandstone contained main mineable coal seam No.9. Shanxi Formation was in mainly delta plain distributary channel facies, flood basin facies and peat bog facies;lithology is mainly sandstone, siltstone and sandy mudstone contained main mineable coal seams Nos.4-1, 4. Coal No.4-1 is mostly mineable and rather stable;coal Nos.4 and 9 are all regional mineable and rather stable;main coal rank is coking coal. Coal re?sources in the area are abundant with rather good coal quality, and higher exploitation values.
