摘要
针对漳村煤矿480 m水平回风大巷服务年限长、煤岩体破碎的特点,依据强力一次支护理论,采用强力锚杆锚索组合支护系统,并进行了井下试验。实践表明,强力锚杆锚索组合支护系统能够有效控制巷道的变形,支护效果明显。
According to characteristics of 480 m level return airflow roadway service life is long, the coal and rock is crushing in Zhangtun Coal Mine, it＇s based on a strong theoretical support, adopt a powerful bolt anchor combined support system, and carried out under-ground tests. The practice shows that a strong anchor rope support system can effectively control the deformation of roadway, the supporting effect is obvious.
