摘要
山脚树矿在煤巷中应用锚杆支护技术 ,顶锚杆使用D2 0× 2 2 0 0mm的建筑螺纹钢锚杆 ,帮锚杆采用D16× 16 0 0mm的建筑螺纹钢锚杆 ,帮、顶均采用端头锚固 ,全断面挂金属网 ,“W”钢带护帮 ,取得了初步成功。介绍了应用该技术的具体情况 ,同时提出了为提高掘进进度所需要解决的几个问题。
This paper relates to application of coal road rock bolting in Shanjiaoshu coal mine.The top anchor bolt is of building thread steel anchor bolt of D20×2 200 mm,and the end anchor bolt is of building thread steel anchor bolt of D16×1 600 mm,both of the top and end anchor bolt being of face end anchored and hanging metal net through the whole cross-section as well as“W” steel helping belt,and achieving preliminary success.This paper introduces this technique in detail and proposes the solutions to several problems solved to improve the advance rate.
