摘要: 为了解决断层带散体煤复合顶煤巷支护技术难题,以枣园煤业有限公司断层带散体煤复合顶巷道为研究对象,通过分析巷道围岩变形失稳机理,以散体煤复合顶巷道内外承载结构控制原理及“一优化三强化”支护原理为指导,提出了“四高”锚杆强化支护技术、预应力长锚索加固破碎顶板技术和高帮锚索梁加固技术为主的巷道围岩控制技术。矿压观测数据表明,断层带散体煤复合顶煤巷支护原理科学,支护技术先进,巷道围岩变形量得到了有效控制。

Abstract: Composite in order to solve the fault medium coal caving roadway supporting technology problems in Zaoyuan coal co., LTD., fault zones repose of composite roof coal roadway as the research object, by analyzing the deformation of roadway surrounding rock instability mechanism, in repose of composite roof coal roadway internal and external bearing structure control theory and "three strengthening a optimization" supporting principle as the instruction, proposed the "four high" anchor strengthening supporting technology, long prestressed anchor cable reinforcement technology and the high broken roof help anchor beam reinforcement technology of roadway surrounding rock control technology. Mine pressure observation data show that the fault zone composite medium coal caving roadway supporting principle of science, and supporting technology is advanced, the surrounding rock deformation of roadway has been effectively controlled.
