永陇矿区丈八井田煤层赋存特征

摘要

通过对永陇矿区丈八井田地质构造、地层、含煤地层、可采煤层的特征分析，揭示井田地质构造较简单，主要可采的2＃、3＃煤层均为结构简单、较稳定的大部可采煤层。含煤建造受到特定古地理环境影响，煤层厚度变化有一定规律，可为下一步煤炭资源开发提供一定指导意义。%The paper analyzed the characteristics of geological structures , strata, coal-bearing strata, workable coal seams in in Zhangba minefield of Yonglong mining area .The results show that the geological structures are relatively simple , the workable №2 and№3 coal seams are simple and stable , and the variation of coal seams thickness has a certain law because the coal-bearing formation is influenced by specific geographical environment .The research can provide some guidance for the further development of coal resources .
