Abstract
In response to the complex coal forming environment and coal seam characteristics of Songlin Coal Mine in Hezhang County,stratigraphy and coal quality analysis methods are used,combined with the determination of vitrinite reflectance,ash content,volatile matter,and trace elements,to analyze the distribution,coal grade,and trace element influence of coal seams in the mining area.Through the collection and comparison of ore bed data,the physical and chemical characteristics of different coal seams are revealed,and technical measures for optimizing coal seam mining strategies are proposed.The research results indicate that the main coal seams in Songlin Coal Mine have high coal grade characteristics,and the thickness of coal seams shows a non-linear relationship with coal grade with burial depth.The deep layer coal quality is excellent but the burial depth is relatively large,which requires relatively high mining technology.The distribution characteristics of trace elements reveal the influence of coal forming environment on coal quality,providing scientific basis for coal quality evaluation and resource development.关键词
