摘要
针对鹤煤六矿2118工作面切眼跨度大、施工工艺复杂、顶板控制难度大的情况,研究工作面切眼的施工工艺和支护技术。结果表明在综放工作面大跨度切眼施工时,根据地质特点、施工设备选择合理的施工方法和合适的支护方式,可以满足生产和安全的需要,提高矿井效率。
In view of the large cutting span, complex construction technology, the difficulty of roof control on 2118 working face of Hemei the sixth mine, the cutting technology and support technique of working face were studied. The result showed that selecting suitable construction method and support pattern in the cutting of fully mechanized caving face with large span according to geological characteristics and construction equipment can meet the demand of production and safety, and improve mining efficiency.
