HN-1# is the first fully working coring well of the Taiyuan Formation (Ty) in the Huinan Coalfield and exploration studies are currently underway on the associated resources of the coal-bearing strata. The HN-1# well is located in the Fufeng thrust nappe structural belt in the south of the Huainan Coalfield. Three coal samples from the Ty were collected from HN-1# and inductively-coupled plasma mass spectrometry and inductively-coupled plasma atomic emission spectrometry were used to determine the Ge content of each sample. Based on proximate and ultimate analyses, microscopy data, and analyses of the ash products, some important findings were made. The Ty coal samples had a relatively high total sulfur (S_t,d) content (4.24%), thus the coal was considered to be a lower ranked coal (high volatility bituminous coal), which also had a low coal ash composition index (k, 1.87). Collodetrinite was the main submaceral of the Ty coal. Small amounts of pyrite particles were found in the coal seams of the Ty, while the contents of pyrite and algae in the top and bottom sections of the coal seam were relatively high, which meant that the swampy peat conditions which existed during the formation of the coal seams were affected by seawater; also the degree of mineralization of the coal seam was relatively high, which is consistent with reducing conditions in a coastal environment setting. Atomic force microscopy (AFM) experiments showed that the modes of occurrence of Ge in the Ty coal were mainly those for organic-bound and adsorbed Ge species. The organic carbon isotope values for the Ty coal ranged from − 24.1‰ to − 23.8‰, with an average value of − 24.0‰, which is equivalent to the value for terrestrial plants (average value − 24.0‰). The Ge content of the Ty coal was 13.57 mg/kg. The Ge content was negatively correlated with volatile matter and the ash yield.

HN-1＃是辉南煤田太原组（Ty）的第一个完全工作的取心井，目前正在对含煤地层的相关资源进行勘探研究。HN-1＃井位于淮南煤田南部阜丰逆冲推覆构造带中。从HN-1＃收集了三个Ty煤样品，并采用电感耦合等离子体质谱和电感耦合等离子体原子发射光谱法测定了每个样品的Ge含量。根据最接近和最终的分析，显微镜数据以及灰分产品的分析，得出了一些重要发现。Ty煤样品的总硫含量相对较高（S _t，d）（4.24％），因此该煤被认为是等级较低的煤（高挥发性烟煤），其煤灰成分指数也很低（k，1.87）。Collodetrinite是Ty煤的主要次要成分。在Ty煤层中发现少量的黄铁矿颗粒，而煤层顶部和底部的黄铁矿和藻类含量较高，这意味着在Ty煤层形成过程中存在着沼泽泥炭条件。煤层受到海水的影响；煤层的矿化度也相对较高，这与沿海环境条件的减少相一致。原子力显微镜（AFM）实验表明，Ty煤中Ge的形成方式主要是有机结合和吸附的Ge种类。Ty煤的有机碳同位素值在− 24.1‰至− 23.8‰之间，平均值为− 24.0‰，相当于陆地植物的价值（平均值-24.0‰）。Ty煤的Ge含量为13.57mg / kg。Ge含量与挥发性物质和灰分产量负相关。
