摘要
介绍了赵固一矿开拓大巷应用高强度锚杆支护的情况,对部分高应力集中巷道高强度锚杆失效的原因进行了分析。通过增加锚杆体强度,发挥锚杆高强支护和锚网索联合支护的作用,发挥工程监测技术作用,进行动态支护设计等措施,改善了巷道的支护效果。
The application of high--strength bolt is introduced in the development roadway of Zhaogu No. 1 Mine, and the bolt supporting failure causes is analyzed. The supporting effect can be bettered by increasing the bolt of intensity, playing the role of high--strength bolt and anchor--network--cable supporting together, playing the role of monitoring technology, making a dynamic supporting design, et.
