近距离煤层大断面开切眼支护设计与掘进技术探讨

Discussion on design and driving technology of large section opening hole support in close coal seam

为更好的解决近距离煤层大断面开切眼支护问题,选择磁窑沟矿11102切眼工作面作为研究对象,对该切眼工作面的施工工艺及支护参数进行系统研究,进行了锚杆强度及支护参数的确定。并进行了切眼巷道的支护设计,为磁窑沟矿极近距煤层的掘进,提供理论联合实际的依据,以保证煤矿的安全生产。

In order to better solve the problem of large cross-section open-cut support in close coal seam,11102 opencut face in Ciyaogou Mine was selected as the research object.The construction technology and support parameters of the cutting face are systematically studied,which provides a theoretical and practical basis for the excavation of very close seam in Ciyaogou Mine,in order to ensure the safe production of the coal mine.
