摘要:综放综采工作面沿空留巷中切顶卸压是煤矿深度开挖工程中的关键技术,以我国某煤矿首个综采放顶煤工作面为例,对该综放综采工作面的围岩结构进行分析,总结了该区域工作面煤层赋予特性,对该工作面煤层开展切顶卸压沿空留巷的技术应用情况进行阐述,通过与一般运输巷沿空留巷围岩控制技术进行对比,总结了该技术的应用效果优势。
Abstract: 'Top-cutting pressure relief in goaf lane of fully mechanized caving face is a key technology in deep excavatiot engineering of coal mine.Taking the fist fully mechanized top coal caving working face in a coal mine as an example, the surrounding rock structure of this working face is analyzed, the characteristics of coal seam in this working face are summarized, and the application of the technology ofgoaf-sidle retaining oadway in this working face is described. By comparing with the control technology of goaf-side retaining roadway ingeneral transportation roadway, the advantages of the application effect of this technology are summarized.
