朔南麻家梁井田主要含煤地层为石炭系太原组和二叠系山西组,共含煤11层,其中可采煤层8层,4、9号煤层为主要可采煤层。4号煤层位于山西组下部,厚度1.35～11.09m,结构复杂,总体呈南部厚度大,中部及北部厚度变小,其厚度变化与下部K4砂岩呈负相关关系并受上部K5砂岩的冲刷影响,在29线以北存在一个北东向的薄煤带,煤厚小于4m;9号煤层位于太原组下部,厚度1.15～18.16m,在北部及东南部(35线附近)厚度皆大于10m,在西南部63线以西及37线以南地区煤层分叉,分叉区面积仅占9号煤层总面积的1/5。9号煤层含2～11层夹矸,以含3～5层夹矸的居多,且多集中分布在煤层下部,反映出9煤层聚煤环境由动荡逐渐趋于稳定的沉积环境。井田内各主要可采煤层层位稳定或比较稳定,虽然厚度有变化但规律性较强,掌握这一规律,对工程施工、煤层对比有一定的指导意义。
The main coal-bearing strata of the Majialiang minefield in Shuonan are the Carboniferous Taiyuan Formation and the Permian Shanxi Formation, with a total of 11 coal layers, of which 8 are explorable coal seams and the 4,9 coal seam is the main recoverable coal seam. The coal seam No.4 is located in the lower part of Shanxi Formation and has a thickness of 1.35 ~ 11.09m. Its structure is complex with a large thickness in its southern part and a small thickness in its central and northern parts. Its thickness has a negative correlation with K4 sandstone in the lower part and is affected by the erosion of the upper K5 sandstone. There is an NE-trending thin coal belt north of line 29, with a coal thickness of less than 4 m. Coal seam No. 9 is located in the lower part of the Taiyuan Formation and has a thickness of 1.15-18.16 m. Thickness is greater than 10 m in the north and southeast (line 35) Coal seams are bifurcated west of line 63 and south of line 37 in the southwestern part of the country, with bifurcation area occupying only 1 / 5.9 of the total area of No. 9 coal seam. Mostly distributed in the lower part of the coal seam, reflecting the coal accumulation environment of 9 coal seam gradually stabilized from turbulence. The main recoverable coal layers in the mine area are stable or relatively stable. Although the thickness changes but the regularity is strong, mastering this rule has certain guiding significance for engineering construction and coal seam comparison.
