摘要
概括了我国沿空留巷技术发展历程和研究重难点,介绍了沿空留巷技术理论和实践方面的研究现状,指出了我国沿空留巷目前存在的主要问题是:中厚煤层、深井开采、综放开采等情况下沿空留巷技术在理论研究和实际应用方面没有形成体系和切实可行的方法;沿空留巷巷道支护设计可靠性不高,可靠性设计理论不健全;沿空留巷支护设计没有引入系统工程概念,支护设备及方法特别是巷旁支护不能完全适应现代煤矿沿空留巷发展需要。
This paper summarized the development history and research difficulties of gob side entry retaining technology in China, and introduced the research status of gob side entry retaining technology. Then pointed out the main problems of gob at present in our country is in the thick coal seam, deep mining and fully mechanized caving under gob technology in theory research and practical application has not formed a system and method is feasible; gob roadway design reliability, reliability design theory is not perfect; gob supporting design without introducing the concept of systems engineering, support equipment and method especially ribside support can not fully meet the needs of modern coal mine gob development needs.
