高应力巷道锚杆支护系统抗撕裂钢带

Research on Anti - tear Steel Band for Bolting System in Roadway of High Stress

针对高应力采区巷道锚杆支护系统中小刚度钢带易被撕裂的特点,对钢带的作用机理进行了分析,指出煤矿巷道常用4种钢带存在的问题,并提出一种新型大刚度抗撕裂M型钢带。

Aim at the specialty that steel band of small rigidity is easy to be teared for bolting system in the roadway of high stress, this paper analyzes affect mechanism of steel band, and points out existent problems for four kinds of steel band used usually in roadway, lastly presents a new kind of anti - tear M- steel band.
