上海庙矿区鹰骏1号井田煤岩特征与沉积环境关系研究

Relationship Between Petrographic Characteristics and Sedimentary Environment of Yingjun No.1 Mine Field in Shanghaimiao Mining Area

成煤沼泽的沉积环境是煤岩在沉积和成岩过程中所处自然地理条件、气候状况、生物发育状况、沉积介质的物理的化学性质和地球化学条件。沉积环境对含煤地层和煤层的形成具有重要的影响和控制作用,不同的沉积环境可形成不同类型的煤田。对煤岩特征及其沉积环境的研究,可查明煤岩的形成、发展和分布规律,指导寻找矿产资源。通过分析研究上海庙矿区鹰骏1号井田煤层煤岩特征,以反演该区域成煤沼泽的沉积环境,主要包括沼泽范围、覆水深度、氧化还原环境、气候情况等。

The sedimentary environment of the coal-forming swamp includes natural geographic conditions,climatic conditions,biological development conditions,physical and chemical properties and geochemical con⁃ditions of the sedimentary media during the process of sedimentation and diagenesis of coal.The sedimentary environment plays an important role in controlling the formation of coal-bearing strata and coal seams.Differ⁃ent sedimentary environments can form different types of coal fields.The study of petrographic characteristics and sedimentary environment can ascertain the formation,development and distribution law of coal and guide the search for mineral resources.By analyzing and studying the petrographic characteristics of coal seams of Yingjun No.1 Mine Field in Shanghaimiao mining area,the sedimentary environment of coal form⁃ing swamp in this area is inversed,mainly including the scope of swamp,overburden depth,redox environ⁃ment,climate,etc.
