掘进工作面空顶区围岩稳定性分析

Analysis of Aurrounding Rock Stability and Key Infl uencing Factors in Goaf Area of Driving Face

目前,国内煤巷掘进装备、锚杆支护技术已经基本成型,煤巷掘进技术的开发和应用取得了较大的进展,煤巷支护设计技术、巷道围岩地质力学与性能测试技术、掘进装备配套设备、支护材料、施工设备等技术迅速发展。本文采用有限元软件FLAC3D对影响工作面顶部围岩结构稳定的原因进行了研究,以确保矿井快速施工,改善工作面空顶区顶板围岩结构的稳定性。

At present,domestic coal roadway excavation equipment and anchor rod support technology have been basically formed,and significant progress has been made in the development and application of coal roadway excavation technology.The design technology of coal roadway support,geological mechanics and performance testing technology of roadway surrounding rock,supporting equipment for excavation equipment,support materials,construction equipment,and other technologies are rapidly developing.The finite element software FLAC3D was used to study the reasons that affect the stability of the surrounding rock structure at the top of the working face,in order to ensure rapid construction of the mine and improve the stability of the roof surrounding rock structure in the goaf area of the working face.
