近距离煤层重复采动下巷道围岩变形机理及稳定性控制

煤炭是我国基础能源,也是国民经济发展的重要保障;其在能源安全保障上具有“压舱石”的基础性和主体性作用,在未来相当长时期内仍将是我国主体能源。长期以来,近距离煤层联合开采中伴随着各种问题,国内外学者和施工技术人员为了解决相关问题,采用不同方法进行了深入研究,取得了一系列研究成果。因此,本项目以龟兹矿业近距离煤层开采技术研究与应用,研发近距离煤层安全高效开采、采掘科学接替、区段煤柱留设和回采巷道合理布置及稳定性控制等关键技术,实现近距离煤层联合开采,提高煤炭资源开采效率,项目切实可行且意义重大。

Analysis of soft rock roadway deformation mechanism in Zhangshuanglou Mine

On basis of ground stress surveying and analysis of physical nature and mechanics character of rock, the deformation mechanism of west main roadway in Zhangshuanglou Mine is studied. It is put forward that engineering mechanics nature, infiltration of water and concentrated stress on pillar are the main factors to affect stability of the west main roadway. The overall thinking used to restore the roadway is raised.
