| 摘 要： | 太原西山煤田赤峪勘查区地层总体为向南南东缓倾的单斜，在此基础上发育有轴向北东的不对称向斜（东社向斜），局部发育短轴背、向斜和一系列与主体向斜轴向大致平行的正断层，并向南西收敛。区内主要含煤地层为石炭系太原组和二叠系山西组，主要可采煤层为2、3、4、8＋9号煤层。根据煤岩煤质分析结果，2号煤层为低中灰一中灰、特低硫—低硫煤，3号和4号煤层为低中灰一中灰分、低硫一中硫分煤，8号和8＋9号煤层属低中灰、中高硫煤，9号煤层属中灰、中硫煤。总体来看赤峪地区可采煤层为低灰-中高灰，特低硫-中高硫、发热量较高、强一特强粘结性的优质焦煤。全区煤层均为发热量较高、强粘结性的焦煤。

| Abstract: | As a whole, the structure in Chiyu exploration area, Xishan coalfield, Taiyuan is a SSE gently dipping monocline. On this ba- sis developed an asymmetrical syncline （Dongshe syncline） with axial trend NE, locally developed brachyanticline, brachysycline and a series of normal faults approximately parallel to principal syncline axial trend, and converging toward southwest. Main coal-bearing strata in the area are Carboniferous Taiyuan Formation and Permian Shanxi Formation; main mineable coal seams have Nos.2, 3, 4 and 8＋9. Based on coal quality analytic results, coal No.2 is a low medium --medium ash, extra low--low sulfur coal; coal Nos.3 and 4 are low medium--medium ash, low--medium sulfur coal; coal Nos.8 and 8＋9 are low medium ash, medium high sulfur coal; coal No.9 is medium ash, medium sulfur coal. As a whole, mineable coal seams in Chiyu area are low--medium high ash, extra low--medium high sulfur, rather high calorific value, strong~-extra strong caking property high quality coking coal. |
