一、我国石炭纪炼焦煤资源的分布我国具有大规模开采价值的含煤系沉积于晚石炭世时期,俗称太原统煤系,该煤系的储量占全国探明储量的27％以上,其中大部分为炼焦煤牌号,主要分布于华北、华东广大地区,以及部分西北、中南和东北地区。煤系总厚为0～719m,一般在70～100m左右,以山西省为中心,向南、北方向发展时,煤系逐渐变薄,向东、西方向延伸,则煤系逐渐增厚。该煤系除大同矿区以北的局部为陆相沉积的低硫煤以外,其余绝大部分地区为海陆相交互沉积的高硫煤。通常在太原统煤系之上多沉积有晚古生代的早二迭世山西统陆相沉积煤系。如我国山西的西山、古交、汾西、潞安,
First, the distribution of China’s carboniferous coking coal resources China has a large-scale mining value of coal-bearing sedimentation in the Late Carboniferous period, commonly known as the Taiyuan coal system, the coal reserves account for more than 27% of the national proven reserves, of which large Part of the coking coal grades, mainly distributed in North China, East China vast area, as well as some northwest, south-central and northeast regions. The total thickness of coal measures is 0 ~ 719m, generally about 70 ~ 100m. When Shanxi Province is the center and the south and north directions are developed, the coal measures gradually become thinner and extend eastward and westward. In addition to Datong coal mine in northern part of the continental deposition of low sulfur coal, the vast majority of the rest area for the sea and land deposition of high-sulfur coal. Usually over the Taiyuan coal measure deposition more Late Paleozoic Early Permian Shanxi continental sedimentary coal series. As China’s Shanxi Xishan, Gujiao, Fenxi, Lu’an,
